点子无法在防火墙后面工作 [英] Pip not working behind firewall

问题描述

我正在尝试从公司防火墙后面使用pip，并且没有任何运气.

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可以工作，但是不可以.

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

我尝试过了...

sudo -E pip install virtualenv

这些代理...

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

...并获得了很长的堆栈跟踪，并以此结束

... 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.似乎需要代理变量以方案开头.所以我再次尝试了以下代理...

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://)

...，我收到以下错误消息

... and I get the following error

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

这是我完全没有代理时遇到的相同错误，尽管设置代理后速度更快.

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 ...

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似乎还可以，除非我尝试使用pip进行尝试.

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并没有帮助.结果相同.

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参数使其在公司防火墙后与我一起工作.

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:

pip install matplotlib

失败的文字是这样的:

无法获取URL https://pypi.python.org/simple/matplotlib/:在那里 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

所以我尝试了这个可行的方法:

So then I tried this which worked:

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