laravel版本：7.24.0

我在命令提示符下运行以下命令。composer require laravel/socialite但它失败了，输出为：

我试过转储自动加载和清除配置，但任何事情都对我没有帮助
由于未真正安装socialite程序包，因此发生错误。我检查了vender/laravel目录，但没有安装socialite。composer尝试下载socialite程序包，但失败。但是composer忽略了socialite包的失败，所以在composer命令完成后，他们找不到Class 'LaravelSocialiteSocialiteServiceProvider'。我不知道为什么要下载socialite包，但我认为主要是网络问题(速度慢或ip位置受阻等(。因此，我通过将socialite包复制到vendor目录来解决问题。
