Internal error when importing PackageVersions\Versions

Bug report

PHPStan triggers an internal error when importing PackageVersions\Versions.

This happens since PHPStan 0.12.89.

Code snippet that reproduces the problem

The website won't let me share it because it errors but this example is enough to trigger it:

<?php

use PackageVersions\Versions;

PHP Fatal error: Cannot declare class _HumbugBox15516bb2b566\Composer\InstalledVersions, because the name is already in use in phar:///app/vendor/phpstan/phpstan/phpstan.phar/vendor/composer/InstalledVersions.php on line 23

Expected output

No error

Did PHPStan help you today? Did it make you happy in any way?

You already know that I love PHPStan ❤️

This bug report is missing a link to reproduction on phpstan.org.

It will most likely be closed after manual review.

Strangely I can't reproduce it locally but I know what caused it, just reverted the commit: phpstan/phpstan-src@b902c38

The file InstalledVersions.php isn't supposed to be prefixed with PHP-Scoper. I thought it's already whitelisted in new versions of Box but looks like it isn't.

Please test phpstan/phpstan with this command: composer require --dev phpstan/phpstan:dev-master --prefer-dist and let me know if it really works :)

And thank you for your kind words! ❤️

Hey @ondrejmirtes :)

Thank you for this library and your reactivity.

I went into the same problem few days ago (while bumping dependencies of a project I work on).
It was only happening in GitlabCI.

I tried to use the dev-master version, as you suggested, and it solved the problem !

So once again, thank you ❤️

Awesome, please switch again to a stable version once 0.12.90 is out :) (in a matter of days)

Worked for us too 🙂
