Credentials in pip.conf for private PyPI

Question

I have a private PyPI repository. Is there any way to store credentials in pip.conf similar to .pypirc?

What I mean. Currently in .py

Answer 1

Given issue 4789 is still open, you can utilize the following approach in your requirements.txt:

--extra-index-url=https://${PYPI_USERNAME}:${PYPI_PASSWORD}@my.privatepypi.com
private-package==1.2.3
...

If you try to run pip install requirements.txt with those environment variables set, you will find that pip still asks for credentials. This is because pip does not interpolate the expression ${PYPI_USERNAME} as one would expect, but rather url encodes it. Your username and password in this example is expressed as https://%24%7BPYPI_USERNAME%7D:%24%7BPYPI_PASSWORD%7D@my.privatepypi.com

The work around here, and I admit there should be a better approach, but we can run pip as a script:

python3 -m pip install -r requirements.txt

From man:

 -m module-name
    Searches sys.path for the named module and runs the corresponding .py file as a script.
