PHP Warning: Class 'Tightenco\Collect\Support\Debug\Dumper' not found in alias.php on line 18

[joshmurrayeu]

I am attempting to start up Valet on my new MacBook Pro using High Sierra 10.13.6.

I have followed the instructions... brew update, brew install php@7.2, etc however, when I run valet install, I am greeted with this stack trace.

Any help would be appreciated.

Thanks

[paulredmond]

I'm getting the same issue, it seems related to laravel/framework#25087.

Also relevant tighten/collect#124

[mattstauffer]

I broke it! Sorry! I will fix it as soon as I get my kids to bed ❤️

[mattstauffer]

I've fixed this problem, but I can't figure out a way to make the fix go out until Laravel 5.7.2 comes out (because I can't tag Collect 5.7.2 with the fix, because then it would be out of sync with the Laravel components).

[paulredmond]

It’s a warning so I’m not seeing anything critical myself with it 😁

[mattstauffer]

Yep, I was thinking the same thing; ignore the warning and it will go away as soon as we tag the next release. :) Thanks!

[mattstauffer]

Reopening so people can find it until it’s fixed.

[satyago]

@mattstauffer Thank you for the quick fix and keeping this record !
Took me a while to find it but now I'm relieved 👍🥇

[joshmurrayeu]

Hi again

I just wanted to let everyone know that this seems to be fixed now. I went to my global composer.json located in my home directory and I removed everything from there with: composer remove vendor/package. Once I had went through all of the removals, I proceeded with a quick composer dump-autoload and lastly a composer clear-cache.

I then required valet again with composer global require laravel/valet and executed valet install.

Works. Thanks @mattstauffer

Josh

[mattstauffer]

Composer global update should fix it for anyone else who runs into this. Or ‘composer global update Laravel/valet’ I think.

[pankaj-ag]

I just ran composer global update and then valet install and getting the following error.

The most often cause of that is using an old PHP version. Valet requires at least PHP 5.6. I suspect yours is older.
What does this output? php -v

[pankaj-ag]

@drbyte
Current php version is php 5.6.37.

[drbyte]

What's in your ~/.composer/composer.json file?

[drbyte]

I think you're using PHP7 versions of packages, but don't have PHP 7 installed.
Therefore for you forcing your global composer config to require PHP 5.6 versions of packages will be necessary until you move to a newer PHP version.

composer global config platform.php 5.6.36
composer global update

[pankaj-ag]

thanks @drbyte
I will try and let you know if this fix the issue.

thanks again for the help.

[Lloople]

I'm having this error.

I tried with composer global update laravel/valet and also the steps suggested by @joshmurrayeu. Any news? 🤔

Valet version is v2.1.1

[joshmurrayeu]

Hi @Lloople

Did you follow all of the steps I noted down or just some of them? I have tried this on multiple machines and it seems to work in every case. Please try once again (remove all of the packages, dump the autoload, clear the cache, require the package once again).

Before you remove all of your packages, I would recommend making a backup of your global composer.json file (you should always do periodic backups of these files anyway).

Please get back and let us know how you get on.

Thanks
Josh

[Lloople]

Hi @joshmurrayeu,

Yes I followed all the steps, and I did it again in case I missed something last time.

It continues to happen, but only in a non-laravel project which have installed tightenco/collect.

Weird thing is that the erro comes from project/vendor/tightenco/collect/src/Collect/Support/helpers.php, so maybe I should open an issue in that package 🤔

[mattstauffer]

@Lloople you have an outdated version of Collect. Your problem has nothing to do with Valet. You need to update collect in that project.

[Lloople]

@mattstauffer this is what composer.lock says on that project

"name": "tightenco/collect",
"version": "v5.7.6",

I think it's the last version (Installed it yesterday)

EDIT: But you gave an idea with that comment. The issue was that this project already required symfony/var-dumper, but an old version: "symfony/var-dumper": "^3.3@dev". I removed that line and run composer update and everything works now. Maybe tightenco/collect should be less flexible on var-dumper version? 🤔

[mattstauffer]

@Lloople if you want to discuss any further let’s move over to collect. But it is relaxed; you may have just needed to update twice (we upped and then re-lowered that exact version constraint if I remember correctly)

[pankaj-ag]

@drbyte your solution worked for me. Thanks.

[adahox]

composer global update worked smooth to me.
