Question

pip已安装在我的系统上，但每当我尝试安装任何软件包时，它都会抛出异常。安装每个包都有同样的例外。我无法在网上找到这个。请帮忙。

Answer 1

urllib使用的pip模块将自动从您的操作系统加载代理配置。

在这种情况下，这会失败，因为您在代理绕过字段中似乎有一些格式错误的代理配置。验证您的代理配置是否正确。在Mac上，在“系统偏好设置”下执行此操作＆gt;网络

Answer 2

绕过代理设置主机部分。我删除了它们，现在工作正常。 ----这对我也有用

Answer 3

如果@Martijn Pieters的回答没有为您解决，请务必选中“绕过代理设置主机”部分。

尝试删除该字段中的地址，点击应用更改，然后重试。
