I work at a company where we cannot publish some (or all) Python modules to pyPI.
95% of the time before last week I would use:
pip/pip3 install [module name]
to install modules that I needed.
If that doesn't work and you have access to the git repo, another command that might be successful is installing directly from the repo. Here's an example:
pip3 install git+https://github.com/[username]/repo
And if you've downloaded the repo using git clone and there's a setup.py, which should be standard for a properly maintained module - you can run:
pip3 install -e .
Remember, sometimes you need to work around less-standard, less user-friendly modules so thankfully there are other pip options that can hopefully serve your needs.
