Installer cannot verify php version - PHP 5.5.16-1+deb.sury.org~precise+1

[mszterlingfsite]

I'm on ubuntu and my php version is

PHP 5.5.16-1+deb.sury.org~precise+1 (cli) (built: Aug 25 2014 10:23:41) 
Copyright (c) 1997-2014 The PHP Group

    with Zend OPcache v7.0.4-dev, Copyright (c) 1999-2014, by Zend Technologies

While using web installer - there is a ajax call to /setup/index.php/environment/php-version
and that is returning error 500

vendor/composer/composer/src/Composer/Package/Version/VersionParser.php:370

Could not parse version constraint 5.5.16-1+deb.sury.orgprecise+1: Invalid version string "5.5.16-1+deb.sury.orgprecise+1"

Just to add comment - installed should be able to deal with error 500 returned by those ajax requests so message can be passed to the user.

I'm on ubntu too and have same issue. My php version is
"PHP 5.5.9-1ubuntu4.6".

For temporary solving issue I reverted changes to "MAGETWO-33385: Run static code tests in setup folder" commit.

Thanks for reporting, we have created internal ticket MAGETWO-34667 for the problem.

If I can suggest - same as Seldaek - change the way it is done in Magento\Setup\Controller\Environment
Example how they parse php version in Composer is
https://github.com/composer/composer/blob/master/src/Composer/Repository/PlatformRepository.php#L38-44

        try {
            $prettyVersion = PHP_VERSION;
            $version = $versionParser->normalize($prettyVersion);
        } catch (\UnexpectedValueException $e) {
            $prettyVersion = preg_replace('#^([^~+-]+).*$#', '$1', PHP_VERSION);
            $version = $versionParser->normalize($prettyVersion);
        }

Same happening to me.

UnexpectedValueException

File:
 /var/www/html/magento2/vendor/composer/composer/src/Composer/Package/Version/VersionParser.php:370

Message:
 Could not parse version constraint 5.5.12-2ubuntu4.2: Invalid version string "5.5.12-2ubuntu4.2"

What's weird is that I've managed to remove disabled="disabled" from button and for once it got me on second screen in setup wizard....and I've finalized the installation.

I agree with the @mszterlingfsite:
preg_replace('#^([^~+-]+).*$#', '$1', PHP_VERSION)
