在虚拟环境中使用代理进行pip安装 [英] pip install using proxy in a virtual environment
问题描述
我在公司笔记本电脑中使用Ubuntu VM进行工作，该笔记本计算机使用代理服务器连接到Internet.
经过一些研究，我发现了如何使用pip install和代理一起安装模块.例如，使用此命令，我可以安装我的virtualenv模块:
I work on a Ubuntu VM in my company's laptop which uses proxy server for connecting to internet.
After some research I found out how to install modules using pip install with proxy. For example, using this command I can install my virtualenv module:
sudo pip install --proxy=http://user:pass@<proxy_address>:<portnumber> virtualenv
但是，在创建虚拟环境文件夹后，将其激活，然后使用以下pip命令安装模块:
However, after creating a virtual environment folder, activate it and then install a module using this pip command:
pip install --proxy=http://user:pass@<proxy_address>:<portnumber> pyperclip
我收到此错误:
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', OSError('Tunnel connection failed: 407 Proxy Authentication Required',))': /simple/pyperclip/
如果我使用sudo，则pip可以下载并安装模块，但使用系统全局软件包而不是在我的虚拟环境中.在我看来，Ubuntu及其代理设置中存在权限问题.
If I use sudo, pip can download and install the module, but in system global package instead of in my virtual environment. It seems for me a permission issues in my Ubuntu and its proxy setting.
如何解决此问题，以便可以在我的virtualenv中本地安装模块?
How can I tackle this issue, so that I can install a module locally in my virtualenv?
谢谢
推荐答案
同时，我知道解决方案. pip需要使用大写字母的环境变量HTTP_PROXY和HTTPS_PROXY而不是http_proxy.
因此，在您的'〜/.bashrc'
Meanwhile, I know the solution. pip needs the environment variable HTTP_PROXY and HTTPS_PROXY in capital letters, instead of http_proxy.
So append below text pattern at the end of your your '~/.bashrc'
HTTP_PROXY=http://username:pass@proxyaddress:port
export HTTP_PROXY
HTTPS_PROXY=http://username:pass@proxyaddress:port
export HTTPS_PROXY
然后运行source ~/.bashrc
现在，您可以使用pip在具有代理登录名的Ubuntu VM中安装所有python软件包.
Then, run source ~/.bashrc
Now you can install all python packages using pip in your Ubuntu VM with proxy login.
