无法通过代理使用PIP进行安装

本文介绍了无法通过代理使用PIP进行安装的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我已经在自定义位置安装了python.

I have installed python over a custom location.

我正在尝试安装一些软件包，但是出现以下错误.我意识到，因为我在VM上，并且他们正在使用代理.

I am trying to install some packages however get the below error. I realized since I am on a VM and they are using proxy. 

C:\python3.7>python -m pip install requests
Collecting requests

  Could not find a version that satisfies the requirement requests (from versions: )
No matching distribution found for requests

因此，我将命令更改为使用代理.它清楚地显示了证书错误，因此我联系了IT支持，他们遇到了自己的问题，这简直令人沮丧.

So I change the command to use the proxy. It clearly shows a certificate error so I contacted IT support and they have their own issues which is only frustrating.

C:\python3.7>python -m pip install requests --proxy=http://proxypac.novartis.net:2010

因此，我在Internet上四处张望，试图找到绕过它的方法，然后尝试.

So I looked all over internet and tried to find to bypass this and tried.

尝试了受信任的主机，但没有成功

Tried trusted host but didn't work out

C:\python3.7>python -m pip install --index-url=http://pypi.org/simple --trusted-host pypi.org --proxy=http://proxypac.novartis.net:2010 requests

使用代理和不使用代理均可轻松安装

Easy install with and without proxy

尝试从git获取

C:\python3.7>python -m pip install git+http://github.com/requests/requests.git
Collecting git+http://github.com/requests/requests.git
  Cloning http://github.com/requests/requests.git to c:\users\gargta2\appdata\local\temp\pip-req-build-dnz33avh

甚至无法使用wheel文件.那太荒谬了.

Not even working with wheel file. That is ridiculous.

如@hoefling在注释中建议的，尝试其他命令，但失败:(

As suggested in comments by @hoefling trying another command but it fails :(

还尝试了其他方法 1.用https更改http 2.我看不到任何pip.ini文件 但似乎没有任何作用.

Also tried other methods 1. changing http with https 2. I don't see any pip.ini file but none seem to be working.

推荐答案

由于您的网络防火墙阻止了您的访问，因此您将需要通过隧道发送pip请求，此链接可以帮助，之后您应该能够通过您的Pip请求建立隧道，可以使用多个VPN提供商允许直通连接，我的建议是NordVPN和DotVPN.

Since your Networks firewall is blocking your access, you will need to tunnel your pip request, this link can help Connect to VPN by Powershell, after that you should be able to tunnel your Pip requests through, there are multiple VPN providers that you can use which allow passthrough connections, My Recommendations are NordVPN and DotVPN.

如果您对通过VPN隧道建立连接有其他疑问，可以在这里查看 https://docs.microsoft.com/zh-CN/powershell/module/vpnclient/add-vpnconnection?view=win10-ps .

If you have additional queries about tunneling your connection through VPN you can have a look here https://docs.microsoft.com/en-us/powershell/module/vpnclient/add-vpnconnection?view=win10-ps.

此外，如果您的网络防火墙阻止了对PyPi的访问，则它们最有可能阻止对VPN的访问，因此，我建议测试一下您尝试通过的VPN是否未被IP阻止. curl的另一种替代方法称为 bitsadmin ，您可以用来验证是否您可以访问vpn，或者只使用老式的ping.

Also if your networks firewall is blocking accessing to PyPi, they are most likely to block access to VPN, so I would recommend testing if the VPN you are trying to tunnel through is not blocked by your IP. There is an alternative to curl known as bitsadmin that you can use to verify if you have access to the vpn, or just use old fashioned ping.

P.S.这两个VPN都有免费层，这就是我的建议.

P.S. Both the VPN's have free tier and that is what I recommend.

如果仍然无法正常工作，请对该错误进行注释.
