How to use pip on windows behind an authenticating proxy

Question

My computer is running windows behind a proxy on a windows server  using active directory   and I can t figure out how to get through it with pip  in python3    I have tried using --proxy  but it still just timeouts   I have also tried setting a long timeout  60s   but that made no difference   My proxy settings are correct  and I compared them with those that I m using successfully in TortoiseHG to make sure   Are there any other tricks that anyone knows of that I can try  or is there some limitation in pip with regards to windows proxies   Update  My failed attempts involved searching pypi   I ve just tried actually installing something and it worked   Searching still fails though   Does this indicate a bug in pip or do they work differently

For me  the issue was being inside a conda environment  Most likely it used the pip command from the conda environment   quot where pip quot  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  quot pip install  quot  there  helped

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   http   ntlmaps sourceforge net

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  quot pip quot  2  Create a file named  quot pip ini quot  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  quot pip install quot  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  quot pip ini quot  file mentioned above

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

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   lt domain gt   lt username gt   lt password gt   lt host gt   lt port gt   pip install  lt packagename gt    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

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
