Python - cant find pip.ini or pip.conf in Windows

Question

I got Python 2.7.8 installed on my Win7 machine, which comes with pip already pre-installed.
I'm successfully able to install new packages from pip and now I need to add custom repository url to the install list of pip

To do so I need to modify pip.ini which is in %APPDATA%\pip\pip.ini according to the Official Manual
However there are no pip folder anywhere (not in Roaming, not in Local, not in LocalLow) nor there exists PyPa folder in: C:\ProgramData\PyPA\pip\pip.conf

Could you tell me where do i search for pip.ini? how to add foreign repo to the install list?

Answer 1

Instead of checking a list of well-known locations, you can ask pip to list the valid locations:

pip config -v list 

---

Fun fact

On the same machine, with the same pip version, the valid locations can vary based on the actual Python version.

Environment: Win 7 x64, the HOME environment variable is set to D:\Home

Python 3.7.3:

> pip config -v list For variant 'global', will try loading 'C:\ProgramData\pip\pip.ini' For variant 'user', will try loading 'D:\Home\pip\pip.ini' For variant 'user', will try loading 'C:\Users\foobar\AppData\Roaming\pip\pip.ini' For variant 'site', will try loading 'C:\Python37\pip.ini' 

Python 3.8.0:

> pip config -v list For variant 'global', will try loading 'C:\ProgramData\pip\pip.ini' For variant 'user', will try loading 'C:\Users\foobar\pip\pip.ini' For variant 'user', will try loading 'C:\Users\foobar\AppData\Roaming\pip\pip.ini' For variant 'site', will try loading 'C:\Python38\pip.ini' 

Answer 2

Finally got it sorted.

Apparently for Windows users pip.ini config file is not created, however can be added manually!

just create new %APPDATA%\pip\pip.ini and content of custom repository:

[install] find-links = https://<login>:<password>@your.repo.com/custom/url
