问题描述
我用以下命令更新了作曲家:
I updated the composer with this command:
composer self-update
它已更新至版本2.0.4.然后，当我尝试使用以下方式启动Laravel项目时:
It was updated to version 2.0.4. Then when I tried to launch my Laravel project using:
php artisan serve
我收到此错误:
In PackageManifest.php line 131:
Undefined index: name
我尝试使用以下方法恢复作曲家的旧版本:
I tried getting back to the old version of the composer with this:
composer self-update --rollback
该作曲者已降级至1.9.3版，但此错误无济于事.然后，我使用此命令再次更新了作曲家:
The composer was downgraded to version 1.9.3, but it didn't help with the error.Then I used this command to update the composer again:
composer self-update --stable
并且仍然出现相同的错误.
And still got the same error.
这是PackageManifest.php文件的第131行:
This is the line 131 of the PackageManifest.php file:
return [$this->format($package['name']) => $package['extra']['laravel'] ?? []];
