Question

我已经在自定义位置安装了python。

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。

C:\python3.7>python -m pip install requests
Collecting requests
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x0424C6F0>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed')': /simple/requests/

  Could not find a version that satisfies the requirement requests (from versions: )

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，这真令人沮丧。

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。

尝试了受信任的主机，但没有成功

使用和不使用代理轻松安装

尝试从git获取

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。

如@hoefling在注释中建议的，尝试其他命令，但失败：（

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。

Answer 1

由于您的网络防火墙阻止了您的访问，因此您将需要隧穿pip请求，此链接可以帮助Connect to VPN by Powershell，此后您应该能够隧穿Pip请求，因此有多个VPN提供商可以您可以使用允许直通连接的方式，我的建议是NordVPN和DotVPN。

如果您对通过VPN建立连接有其他疑问，可以在https://docs.microsoft.com/en-us/powershell/module/vpnclient/add-vpnconnection?view=win10-ps处查看。

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。卷毛还有一种替代方法，称为bitsadmin，可用于验证您是否有权访问vpn，或仅使用老式的ping。

P.S。这两个VPN都有免费层，这就是我的建议。

如果仍然无法正常工作，请对该错误进行注释。
