我正试图在工作中通过代理使用pip。

这篇文章中的一个答案建议使用CNTLM。我安装和配置它根据这另一个帖子,但运行cntlm.exe -c cntlm.ini -I -M http://google.com给出错误连接到代理失败,退出。

我还尝试了pip install——proxy=user:pass@localhost:3128(默认的CNTLM端口),但会引发无法获取索引基础URL http://pypi.python.org/simple/。很明显代理出问题了。

有人知道如何更明确地检查CNTLM是否设置正确,或者是否有另一种方法完全绕过这个问题吗?我知道你也可以像这里描述的那样设置http_proxy环境变量,但我不确定要放入什么凭证。来自cntlm.ini的那些?

打开Windows命令提示符。

设置代理环境变量。

set http_proxy=http://user:password@proxy_ip:port
set https_proxy=https://user:password@proxy_ip:port

在相同的Windows命令提示符中使用代理安装Python包。

pip install --proxy="user:password@proxy_ip:port" package_name

其他回答

这对我来说很有效(在Windows上通过CMD):

pip install --proxy proxyserver:port requests

我可以通过运行:

pip install --proxy=http://user:pass@your.proxy.com:3128 package==version

我在公司代理中使用Python 3.7.3。

安装PIP:

ex:PORT = 9090
ex:PROXY_SERVER = stackoverflow
USERNAME:your user id
PASSWORD: your password

sudo pip2 install PACKAGENAME——proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/ for Python2.7

sudo pip3 install PACKAGENAME——proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/ for Python3.5

例子:

sudo pip2 install pandas --proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/

对于apt-get安装

sudo http_proxy=http://USERNAME:PASSWORD@PROXY_SERVER:PORT/ apt-get install PACKAGENAME

例子:

sudo http_proxy=http://USERNAME:YOURPASSWORD@PROXY_SERVER:PORT/ apt-get install tensorrt

sudo http_proxy=http://USERNAME:YOURPASSWORD@PROXY_SERVER:PORT/ apt-get update

我得到了错误:

chris@green:~$ sudo http_proxy=http://localhost:3128 pip install django==1.8.8 
Downloading/unpacking django==1.8.8
  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement django==1.8.8
No distributions at all found for django==1.8.8
Storing complete log in /home/chris/.pip/pip.log

(代理服务器的端口是ssh端口转发到localhost:3128)。

我必须同时设置http和https代理使其工作:

chris@green:~$ sudo http_proxy=http://localhost:3128 https_proxy=http://localhost:3128 pip install django==1.8.8
Downloading/unpacking django==1.8.8

http://pypi.python.org/simple/重定向到https://pypi.python.org/simple,但pip的错误没有告诉你。

$ pip --proxy http://proxy-host:proxy-port install packagename

这对我来说很管用
