我得到這個錯誤:Symfony的作曲家更新
C:\wamp64\www\Symfony>php composer.phar self-update
Updating to version ded485d.
[Symfony\Component\Console\Exception\RuntimeException] Too many arguments, expected arguments "command" "version". self-update [-r|--rollback] [--clean-backups] [--no-progress] [--update-keys] [--stable] [--preview] [--snapshot] [--] []
問題應該清楚,用英語問問! –
