如何在身份验证代理后面的窗口上使用 pip

我的计算机在 Windows 服务器的代理后面运行 windows (使用活动目录) ，我不知道如何使用 pip(在 python3中)完成它。我试过使用 --proxy，但它仍然只是超时。我也试过设置一个长时间的超时(60秒) ，但是没有什么区别。我的代理设置是正确的，我将它们与我在 TortoiseHG 中成功使用的代理设置进行了比较，以确保。

是否有任何其他的技巧，任何人都知道，我可以尝试，或者有一些限制在 pip的窗口代理？

更新: 我失败的尝试包括搜索 Pypi。我刚刚试着安装了一些东西，它起作用了。不过搜寻仍然失败。这是否意味着 pip中存在 bug，或者它们的工作方式不同？

I had a similar issue, and found that my company uses NTLM proxy authentication. If you see this error in your pip.log, this is probably the issue:

Could not fetch URL http://pypi.python.org/simple/pyreadline: HTTP Error 407: Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )

NTLMaps can be used to interface with the NTLM proxy server by becoming an intermediate proxy.

Download NTLMAPs, update the included server.cfg, run the main.py file, then point pip's proxy setting to 127.0.0.1:.

I also needed to change these default values in the server.cfg file to:

LM_PART:1
NT_PART:1


# Highly experimental option. See research.txt for details.
# LM - 06820000
# NT - 05820000
# LM + NT -
NTLM_FLAGS: 07820000

I have tried 2 options which both work on my company's NTLM authenticated proxy. Option 1 is to use --proxy http://user:pass@proxyAddress:proxyPort

If you are still having trouble I would suggest installing a proxy authentication service (I use CNTLM) and pointing pip at it ie something like --proxy http://localhost:3128

It took me a couple hours to figure this out but I finally got it to work using CNTLM and afterwards got it to work with just a pip config file. Here is how I got it work with the pip config file...

Solution:

1. In Windows navigate to your user profile directory (Ex. C:\Users\Sync) and create a folder named "pip"

2. Create a file named "pip.ini" in this directory (Ex. C:\Users\Sync\pip\pip.ini) and enter the following into it:

    [global]
trusted-host = pypi.python.org
pypi.org
files.pythonhosted.org
proxy = http://[domain name]%5C[username]:[password]@[proxy address]:[proxy port]

Replace [domain name], [username], [password], [proxy address] and [proxy port] with your own information.

Note, if your [domain name], [username] or [password] has special characters, you have to percent-encode | encode them.

3. At this point I was able to run "pip install" without any issues.

Hopefully this works for others too!

P.S.: This may pose a security concern because of having your password stored in plain text. If this is an issue, consider setting up CNTLM using this article (allows using hashed password instead of plain text). Afterwards set proxy = 127.0.0.1:3128in the "pip.ini" file mentioned above.

I ran into the same issue on windows 7. I managed to get it working by creating a "pip" folder with a "pip.ini" file inside it. I put this folder inside "C:\Users\{my.username}\AppData\Roaming", because according to the Python documentation:

On Windows the configuration file is %APPDATA%\pip\pip.ini

In the pip.ini file I have only:

[global]
proxy = [proxy address]:[proxy port]

So no username:password. And it is working just fine.

This is how I set it up:

  1. Open the command prompt(CMD) as administrator.

  2. Export the proxy settings :

    set http_proxy=http://username:password@proxyAddress:port

    set https_proxy=https://username:password@proxyAddress:port

  3. Install the package you want to install:

    pip install PackageName

For example:

You may also run into problems with certificates from your proxy. There are plenty of answers here on how to retrieve your proxy's certificate.

On a Windows host, to allow pip to clear your proxy, you may want to set an environment variable such as:

PIP_CERT=C:\path\to\certificate\file\in\pem\form\myproxycert.pem

You can also use the --cert argument to PIP with the same result.

I had the same issue on a remote windows environment. I tried many solutions found here or on other similars posts but nothing worked. Finally, the solution was quite simple. I had to set NO_PROXY with cmd :

set NO_PROXY="<domain>\<username>:<password>@<host>:<port>"
pip install <packagename>

You have to use double quotes and set NO_PROXY to upper case. You can also add NO_PROXY as an environment variable instead of setting it each time you use the console.

I hope this will help if any other solution posted here works.

install cntlm: Cntlm: Fast NTLM Authentication Proxy in C

Config cntlm.ini:

Username ob66759

Domain NAM

Password secret

Proxy proxy1.net:8080

Proxy proxy2.net:8080

NoProxy localhost, 127.0.0.*, 10.*, 192.168.*

Listen 3128

Allow 127.0.0.1

#your IP

Allow 10.106.18.138

start it:

cntlm -v -c cntlm.ini

Now in cmd.exe:

pip install --upgrade pip --proxy 127.0.0.1:3128

same issue on windows10 and above solutions are not working for me.

use a emulator console tool like cygwin and then do it the default linux way:

export http_proxy=<proxy>
export https_proxy=<proxy>
pip install <package>

and things are working fine.

Try to encode backslash between domain and user

pip --proxy https://domain%5Cuser:password@proxy:port install -r requirements.txt

For me, the issue was being inside a conda environment. Most likely it used the pip command from the conda environment ("where pip" pointed to the conda environment). Setting proxy-settings via --proxy or set http_proxy did not help.

Instead, simply opening a new CMD and doing "pip install " there, helped.
