pip安装请求错误

Question

尝试安装请求，收到以下错误消息。我还尝试手动下载它们并根据本地文件运行相同的代码，但我遇到了同样的问题。我不认为它在请求方面，因为如果我尝试通过pip下载任何内容，我会得到相同的错误消息。

Answer 1

sudo -H pip install requests --proxy="my_proxy_name:port"

试试这个

Answer 2

简单的方法是提供代理信息。

 pip install --proxy=user:pass@server:port requests

第二种方法是使用导出代理设置

set http_proxy=http://username:password@proxyAddress:port
set https_proxy=https://username:password@proxyAddress:port
pip install requests

Answer 3

这种情况发生在我身上，我启动了一个Vagrant虚拟机，即当互联网出现故障时通过vagrant up。我想，在它恢复之后，网络设置从未更新过。

我所要做的就是暂停VM并重新启动它。问题消失了。

也许这有助于某人。
