Composer\Config::setAuthConfigSource()

[soullivaneuh]

Since using latest version (6b6d1ab), I have the following error while running ./bin/satis build:

PHP Fatal error:  Call to undefined method Composer\Config::setAuthConfigSource() in /[...]/vendor/composer/satis/src/Composer/Satis/Command/BuildCommand.php on line 587

And indeed, Composer\Config::setAuthConfigSource method doesn't exist.

I'm having the same issue.

Quick workaround is:

git checkout HEAD^1

Fixed now, once you get latest and run a composer install
