In Brew.php line 187: Unable to determine linked PHP.

[orangeShadow]

I try methods: composer global update, install php 72, brew upgrade, but error repeat and repeat ? what can i do, to run service ? valet version 2.0.8

[donaldallen]

I've had the same problem tonight, and here's what I did to get it running:

brew unlink php && brew link php
brew services restart --all
composer global update
valet start

It would be nice if Valet had some suggestions on what to do when "Unable to determine linked PHP." comes up.

Two code references:
https://github.com/laravel/valet/blob/master/cli/Valet/Brew.php#L178-L179
In this one it's looking to ensure that the php binary is linked. So, if you've unlinked all the installed PHP versions, then you'll get that error message.

Next it moves on to verify that the linked php binary is a supported one, per this list:
https://github.com/laravel/valet/blob/master/cli/Valet/Brew.php#L53-L56

[olivernybroe]

Getting some error here, tried to follow my symlink and it looks like this ../Cellar/php/7.2.2_14/bin/php.

Looking at how it matches, it looks for a full path containing one of the supported versions.

The supported php version looks for strings named like this php72, which of course is not in the path.

[scherii]

@Uruloke Should this not be caught by the first item php?

[orangeShadow]

uruloke, Yes, I commented locally this checking, and valet was started, but it is not good decision

[olivernybroe]

@scherii You are right, it should be caught by that, didn't see it. Gotta test this out a little locally and see if I can find an great solution.

[olivernybroe]

After cloning the repo I can't reproduce the error, lol.
If OP or someone else could tell how to reproduce the error, I will gladly try to fix it.

[orangeShadow]

Try brew update php to another version and change link

[olivernybroe]

@orangeShadow Just uninstalled php72 then installed php71, linked to php71, upgraded to php72 and linked to php72, then ran valet start and everything seems to work.

[orangeShadow]

@Uruloke, Can you write your file path and name for php link

[lesaff]

Brew has promoted php7.2 to core, so it is called php now.
https://github.com/laravel/valet/blob/master/cli/Valet/Brew.php#L185 will always throw exception until the logic is revised.

To get mine working, I edited
/Users/<your_username>/.composer/vendor/laravel/valet/cli/Valet/Brew.php
from

return strpos($resolvedPath, "/$version/") !== false;

to

if ($version === 0 || strpos($resolvedPath, "/$version/") !== false) return true;

[Zegnat]

@scherii,

Should this not be caught by the first item php?

You’d think that. But for some reason it didn’t for me on the path ../Cellar/php/7.2.3_2/bin/php… But when I added an item '7.2.3_2' to the array on that line all worked fine. No clue what’s tripping it up there.

[MelMacaluso]

brew unlink php && brew link php
brew services restart --all
composer global update
valet start

That fixes it for me, somehow.

[delino12]

ln -s /usr/local/Cellar/php71/7.1.16_1/bin /usr/local/bin/php

[kroko]

wild guess that most people here having the issue only care if it's 7.1+ and thus are fighting an unnecessary fight. if possible just trash all php things from the system with uninstall, doctor, cleanup and just install newest php (currently 7.2) and formula name will be php not php@version, it has been fixed in brew core formula names for some time and install php@version is used only if you explicitly want older php.

valet install

In Brew.php line 182:
Unable to determine linked PHP.

brew unlink php && brew link php

Error: No such keg: /usr/local/Cellar/php

brew install php worked in my case to resolve the issue

valet install

Valet installed successfully!

[aurawindsurfing]

Also here is a nice comprehensive guide to upgrading brew and php. Nicely put together:

[mikoop79]

this worked for me...

brew unlink php

brew link --overwrite php

valet install

[eddy80310]

If you follow donaldallen's comment and it still doesn't fix it you can check if it's symlinked correctly.

$ which php
/usr/local/opt/php@7.1/bin/php

Then create a symlink to where this is looking for it: https://github.com/laravel/valet/blob/master/cli/Valet/Brew.php#L181

ln -s /usr/local/opt/php@7.1/bin/php /usr/local/bin/php

That was the fix on mine.

[orangeShadow]

Hi, I found problem !!!!

return $this->supportedPhpVersions()->first(function ($version) use ($resolvedPath) {
            $resolvedPathNormalized= preg_replace('/([@|\.])/', '', $resolvedPath);
            $versionNormalized = preg_replace('/([@|\.])/', '', $version);
            return strpos($resolvedPathNormalized, "/$versionNormalized/") !== false;
        }, function () {
            throw new DomainException("Unable to determine linked PHP.");
        });

In line 187 $version is a key of constant's array, but if you set second parameter it would be a $version

return $this->supportedPhpVersions()->first(function ($key, $version) use ($resolvedPath) {
            $resolvedPathNormalized= preg_replace('/([@|\.])/', '', $resolvedPath);
            $versionNormalized = preg_replace('/([@|\.])/', '', $version);
            return strpos($resolvedPathNormalized, "/$versionNormalized/") !== false;
        }, function () {
            throw new DomainException("Unable to determine linked PHP.");
        });

[OZZlE]

The code seems to check only if php is a symlink, however I just installed MacOs High Sierra in the latest version and it comes with PHP 7.1.14 which should be fine in many cases, might even be wanted by some systems that don't fully work with PHP 7.2...

So I think the logic should take into consideration that the systems built in PHP version might be okay as well!

Brew.php:

    if (!$this->files->isLink('/usr/local/bin/php')) {
        throw new DomainException("Unable to determine linked PHP.");
    }

[drbyte]

I think this can be closed, as multiple improvements have been made to address the homebrew changes that precipitated this.

[mssdef]

fixed by:

$ ln -s /usr/local/opt/php@7.0/bin/php /usr/local/bin/php

[AK-PapaSoft]

My way to fix this was ti rewrite current php version: brew link php@7.1 --force --overwrite
That worked for me in similar case. If you have questions in the whole process - ping me as well. Probably, I can help ;)

this works for me too.

(I try to follow the docs on laravel.com to run brew install php@7.2, but it failed)

[mattstauffer]

@hezll If "Unable to determine linked PHP" is on your line 182, you're not running the latest version of Valet. Please update and try again if you have any issues. Thanks!

[andrey-bondarenko]

This helped me

in file: /Users//.composer/vendor/weprovide/valet-plus/cli/Valet/Brew.php

on line: 16
const PHP_V72_BREWNAME = 'php';

change to :

const PHP_V72_BREWNAME = 'php@7.2';

[shane-smith]

Hmm, interesting.

brew unlink php@7.1 && brew link php@7.1 --force

Unlinking /usr/local/Cellar/php@7.1/7.1.25... 0 symlinks removed
Linking /usr/local/Cellar/php@7.1/7.1.25... 25 symlinks created

The symlinks were initially missing.

Afterwards, valet install works. 💯

---

@tucq88 and @thomasbyoung - try one of the following, depending on what version of PHP you have installed on your system:

• brew unlink php@7.2 && brew link php@7.2 --force
• brew unlink php@7.1 && brew link php@7.1 --force
• brew unlink php && brew link php --force

Then re-try the valet install command.

[tucq88]

No luck for me :(

[tucq88]

Now it's on line 205 =))

[drbyte]

@tucq88 please answer the questions I posted above.

[OZZlE]

Hmm, interesting.

How is it interesting? It's an obvious bug that these people won't fix for some reason... See: #533 (comment)

[mattstauffer]

@OZZlE These people? Please direct me to the pull request where you fixed it and I'll be more than happy to review it.

[mattstauffer]

For anyone who is curious, we're taking a look and trying to figure out a good solution. "Just allow non-Homebrew PHP" may not be a good enough solution; "just allow non-symlinks" may not be a good enough solution; "I have to run a Homebrew command to get my Valet working and therefore it's Valet's fault" is a bad take.

If anyone has all of this in their brain and can fully conceptualize the best fix, please, create a new issue and/or pull request and guide us here. Otherwise, please respect the amount of work @drbyte has put into helping people here--with no benefit or payment to himself.

[shane-smith]

Perhaps a quick fix (meanwhile) is to document any workarounds as part of the install instructions. I suspect anyone installing this on a fresh machine with latest macOS will run into the problem.

This looks to be the place: https://github.com/laravel/docs/blob/5.7/valet.md#installation

I may be able to submit something myself, but likely not this week.

Sorry I was a bit cranky :) What about doing like this: if php is exists and is not a symlink; output this php with version and ask the user if they would like to keep it or update to the latest php, if they go with latest then force symlink it to that.

[mattstauffer]

I think we have a fix (written by @drbyte, no surprise) on master. Anyone who wants to take a look can; I'm letting it sit there for a few days before I release, but I'll likely release within the next day or two.

[Vinai]

Is this out already?

[mattstauffer]

@Vinai Yep: https://github.com/laravel/valet/releases/tag/v2.1.6

[aado29]

So to solve the problem, simply create the directory with sudo mkdir /usr/local/sbin and then set the correct ownership on it with sudo chown -R `whoami`:admin /usr/local/sbin.

then:

$ brew unlink php && brew link php
$ brew services restart --all
$ composer global update
$ valet start

[frank-f5w]

I found two ways to resolve this on my machines.

First is to not use a specific version of php:
$ brew install php (you'll get the latest one)
$ brew link php
$ valet restart

Second solution is for when you want to use a specific version of PHP:
$ brew install php@7.2
$ brew link php@7.2
$ valet use php@7.2 (which will restart, too)

[icarojobs]

Type of @delino12 solve my problem! Thanks dude!

[brianhogg]

Returning to this thread I already replied to after spending an hour trying to get it to work :)

brew install php doesn't install 7.3 but grabs 7.2 (after a brew update and upgrade)
brew link php@7.3 gives Warning: php@7.2 is keg-only and must be linked with --force

and no matter what valet start or valet restart gives the unable to determine linked php error. Stumped.

[drbyte]

@brianhogg Ya, the brew update should have made sure you have the latest version endpoints to install for.
My first reaction is that that maybe suggests something amuck with your homebrew install.
I'd start by running brew doctor and exploring its suggestions.

A more aggressive advanced step you could explore is to delete your /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core directory, and then run brew doctor again to have it re-install the core taps that are used for installing php with brew.

Also, what does valet --version say? Today the latest is 2.3.3.

[pmochine]

@delino12 helped me a lot! However, first you need to understand that you still have two php version on your mac.

When you use an empty .php file and write down phpinfo(); you might see that the version is not correctly installed, even though if you type down php -v in your terminal you see the newest version.

What I found out is that you need to create a new symlink for your mac.

1. Find out where your newest php is. Use for example which php or brew list php
2. Now you need to remove the local php that is installed with rm -f /usr/local/bin/php. This removes the php bin file.
3. Now we are creating a symlink to the newest php bin file just by: ln -s /usr/local/Cellar/php/7.3.10/bin /usr/local/bin/php (Warning! Please update the first path to the path you saw with which php)

Now it works for me :) I hope it helped you as well

[drbyte]

Rather than manually linking, Homebrew can do the symlinking for you:

brew unlink php@7.2
brew link php@7.3

Sometimes adding --force can be useful.

[grafxflow]

Anybody using macOS 10.15 the file to amend now is ~/.zshrc.

Example being.

# export PATH="/usr/local/opt/php@7.1/bin:$PATH"
# export PATH="/usr/local/opt/php@7.1/sbin:$PATH"
# export PATH="/usr/local/opt/php@7.2/bin:$PATH"
# export PATH="/usr/local/opt/php@7.2/sbin:$PATH"
export PATH="/usr/local/opt/php@7.3/bin:$PATH"
export PATH="/usr/local/opt/php@7.3/sbin:$PATH"

And now this works fine for me. Best to also open a new terminal to see it working.

brew unlink php@7.2 && brew link --force php@7.3  

[LeRoyJulian]

After updating to PHP 7.4 :

In Brew.php line 251:
Unable to determine linked PHP when parsing '7.4' 

[cuddimatic]

I had the same issue, and this was what I did to fix it:

Check your current php version
brew unlink php
valet use php@current version ( eg:- valet use php@7.4 )
brew services restart --all
composer global update
valet start

Hopefully, this helps🙂

[drbyte]

Im use Valet+ this code bellow help me:
brew unlink valet-php@7.2 && brew link --force valet-php@7.2

Discussion about Valet-Plus should be done in their repository.
(Otherwise the advice given might be irrelevant/incomplete/incorrect. Such as in this case, where valet-php doesn't exist in official Laravel Valet.)

[israelguido]

sorry!

[AlvinQinwen]

Valet doesn't support PHP version: php@7.4 (try something like 'php7.2' ins tead)
but some vender need php@7.4
how i to do?

[mattstauffer]

@AlvinQinwen please open a new issue if you have questions. Also, please update your copy of Valet and re-test before you do.

[ivansempijja]

I had the same issue using php 8.3, All the above solutions did not work.
what I had to do was to update valet

composer global update
composer global require laravel/valet
valet install

this should do the trick

[7morimax]

I've had the same problem tonight, and here's what I did to get it running:

brew unlink php && brew link php brew services restart --all composer global update valet start

It would be nice if Valet had some suggestions on what to do when "Unable to determine linked PHP." comes up.

Funiconó para mi, gracias!
