【问题描述】：

我想为我正在制作的 Laravel 聊天应用安装一个包。运行“composer require foo/bar”时，终端出现以下错误：

In RemoteFilesystem.php line 515:

The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Unable to find the socket transport "proxy_user_name" - did you forget to enable it when you configured PHP?

我正在使用 ***，但它仍然指的是我的代理凭据，由于 ***，我应该看不到它。

当运行“作曲家诊断”时，我得到了这个：

什么可能导致错误？

【参考方案1】：

这是由于代理配置错误。尝试更正您的代理或使用

（暂时）禁用它

unset http_proxy;
unset https_proxy;

当需要通过代理时，您可以使用 redsocks。
