Ubuntu: Custom version string messes with version comparison checks #4319

zanbaldwin · 2015-07-30T16:14:37Z

The config.platform.php setting is currently messing up the version comparison checks in Composer on Ubuntu (14.04.1, Linux 3.16.0-45, x86_64). Without the setting, everything installs correctly without errors; however the following error occurs when it is present:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for humbug/humbug dev-master -> satisfiable by humbug/humbug[dev-master].
    - humbug/humbug dev-master requires php >=5.4.0 -> your PHP version (5.5.9-1ubuntu4.11) does not satisfy that requirement.

Since this custom version string will occur on every single installation of PHP installed through Ubuntu's package manager (default repositories), this will affect many people - especially since Symfony are now using the config.platform.php setting in their new Demo application since v0.4.0.

The composer.json file I used to test this is as follows:

{
    "name": "composer/version-resolution-issue",
    "description": "",
    "minimum-stability": "dev",
    "require": {
        "humbug/humbug": "dev-master"
    },
    "config": {
        "platform": {
            "php": "5.3.9"
        }
    }
}

Since I'm referencing the master branch of humbug/humbug and liable to change, the commit at the time of testing was humbug/humbug@facf911.

The text was updated successfully, but these errors were encountered:

Well, the version comparison is not messed up. The only thing being messed up is the display of the php version in error messages (it should take it from config.platform.php when defined as this is the version used during the dependency resolution)

alcohol · 2015-07-31T07:05:48Z

Yes, the error it is actually throwing is that "5.3.9" is below the requirement of ">=5.4.0". But in the error it displays the actual PHP version, not the one defined through "config.platform.php".

alcohol · 2015-07-31T07:33:49Z

Not so easy to fix it turns out. Might be able to make the message more clear for the time being however.

Duplicate of #2697 also.

so how to fix this please ?
Your requirements could not be resolved to an installable set of packages.

Problem 1
- doctrine/migrations dev-master requires php >=5.4.0 -> your PHP version (5.3.10-1ubuntu3.20) or "config.platform.php" value does not satisfy that requirement.

alcohol · 2015-10-03T16:38:44Z

In your case you simply don't have the required php version. Upgrade your
installation of php.

I have the same error, described here
http://stackoverflow.com/questions/ask

My php version is 5.5.31. The error i am getting says :
- doctrine/migrations v1.2.2 requires php >=5.4.0 -> your PHP version (5.5.3

or "config.platform.php" value does not satisfy that requirement.

5.5.3 > 5.4.0 thus there should not be error.
What can be done.

gintares · 2016-01-22T20:29:59Z

Seems a solution can be to use flag --ignore-platform-reqs
composer update --ignore-platform-reqs

xabbuh · 2016-01-22T23:09:01Z

@gintares Are you sure you do not have a custom PHP version configured in your composer.json file?

alcohol · 2016-01-25T07:25:23Z

@xabbuh if he is using the latest Composer version, then that custom version should now be rendered in this message.

xabbuh · 2016-01-25T08:22:05Z

@alcohol So the string or "config.platform.php" valuewill even be displayed if the option wasn't used in the composer.json file?

alcohol · 2016-01-25T08:33:47Z

Huh, seems I am mistaken:

composer/src/Composer/DependencyResolver/Rule.php

Line 210 in a6beb7f

    
           $text .= ' -> your PHP version ('. phpversion() .') or value of "config.platform.php" in composer.json does not satisfy that requirement.';

I thought we worked on this a while ago.

alcohol · 2016-01-25T08:35:57Z

Yeah see #4321. Not sure which of the messages is displayed here though.

elvismdev · 2016-02-05T06:05:55Z

So there's a fix for this yet? I'm using the latest version of composer and when adding packages to a Symfony2 installation I'm getting the same errors. I use Ubuntu as well.

cs278 · 2016-02-05T10:04:45Z

@elvismdev near the end of that file, platform = 5.3.9.

alcohol · 2016-02-05T10:09:08Z

What @cs278 said. Because you specify a specific php version under platform, Composer will treat that version as the "installed" php version, and 5.3.9 is < 5.5.

elvismdev · 2016-02-05T15:02:37Z

Thanks @cs278 @alcohol it finally worked, Symfony2 installer adds this specific platform parameter. Seems like Symfony folks are having a discussion over there if it should be kept or not by default because is causing confusion with many other users.
