I have problem with downloading twitter/bootstrap package v2.2.2 from packagist by composer.
The error message is after trying to download the package:
[Composer\Downloader\TransportException] The "https://api.github.com/repos/twitter/bootstrap/zipball/v2.2.2" file co uld not be downloaded (HTTP/1.1 404 Not Found)
It's a little weird because the version really exists. I'm using composer on windows and I have never had such a problem yet.
composer diagand see what it outputs. Maybe Github was down for a moment. - Sven
