Pip 不在防火墙后面工作 [英] Pip not working behind firewall

问题描述

我试图从公司防火墙后面使用 pip，但没有任何运气.

I am trying to use pip from behind a corporate firewall, and not having any luck.

我已经设置了 http_proxy 和 https_proxy 环境变量.wget 有效，但 pip 无效.

I have set the http_proxy and https_proxy environment variables. wget works, but not pip.

我试过了……

sudo -E pip install virtualenv

使用这些代理...

export http_proxy=myproxyname.mydomain.com:8080
export https_proxy=myproxyname.mydomain.com:8080 

... 并得到了一个很长的堆栈跟踪，以这个结束

... and got a long stacktrace which ended with this

/requests/packages/urllib3/poolmanager.py", line 214, in __init__
'Not supported proxy scheme %s' % self.proxy.scheme
AssertionError: Not supported proxy scheme None

我查看了 poolmanager.py 源代码.看起来它要求代理变量以一个方案开始.所以我再次尝试使用以下代理...

I looked at the poolmanager.py source. It looks like it is requiring the proxy variables to begin with a scheme. So I tried again with the following proxies ...

export http_proxy=http://myproxyname.mydomain.com:8080
export https_proxy=https://myproxyname.mydomain.com:8080 (also tried this with http://)

...我收到以下错误

Downloading/unpacking virtualenv
  Cannot fetch index base URL https://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement virtualenv
Cleaning up...
No distributions at all found for virtualenv
Storing debug log for failure in /root/.pip/pip.log

这与我根本没有代理时得到的错误相同，尽管在设置代理后我得到的速度要快得多.

This is the same error I get when I do not have a proxy at all, though I get it much faster when the proxies are set.

当我尝试 wget 时......

When I try wget ...

wget --no-check-certificate https://pypi.python.org/simple/

它工作正常，所以我认为代理本身看起来还可以，除非我用 pip 尝试它们.

It works fine, so I think the proxies themselves seem ok, unless I try them with pip.

使用 --proxy 选项代替 envvars 没有帮助.相同的结果.

Using the --proxy option instead of envvars did not help. Same results.

有什么想法吗?

谢谢，豆

推荐答案

使用 --trusted-host 参数.

Use the --trusted-host argument.

我想出了如何使用 --trusted-host 参数让它在我的公司防火墙后面与我一起工作.

I figured out how to get it to work with me behind my corporate firewall using the --trusted-host argument.

我的第一次尝试是这样的:

My first attempt was this:

pip install matplotlib

失败的文本是这样的:

无法获取 URL https://pypi.python.org/simple/matplotlib/:有确认 ssl 证书时出现问题:[SSL:CERTIFICATE_VERIFY_FAILED] 证书验证失败 (_ssl.c:645) -跳过

Could not fetch URL https://pypi.python.org/simple/matplotlib/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645) - skipping

然后我尝试了这个工作:

So then I tried this which worked:

pip3.5 安装 matplotlib --trusted-host pypi.python.org
