How to use `pip` and setup.py to automatically install dependencies that may be private repositories hosted on github

问题

I don't think this is a dupicate, because I tried all links I could find for the past 2 hours and none of the solutions worked. I want the user to be able to clone a repository, cd into the directory, and run $ pip install . (or at least pip install --process-dependency-links .) to install the package, its pypi dependencies AND its (latest) private github dependencies assuming the user has read permissions for them. (also the devs should be able to run $ pip install -e .)

my setup.py:

setup (
    ...
    install_requires=['
        ...
        private-pkg
        ...
    ],
    dependency_links=[
        'git+ssh://git@github.com/private-org/private-pkg.git@master#egg=private-pkg'],
    )

I also tried different variations for dependency_links:

https://github.com/private-org/private-pkg/tarball/master#egg=private-pkg
git+https://git@github.com/private-org/private-pkg.git@master#egg=private-pkg

I also tried adding a trailing -1.0.0 (for version) and it doesn't work but in any case, I'd like the user to be able to install the lastest version

Note that I can do:

pip install "git+https://github.com/private-org/private-pkg" and it works fine, but I can't get pip install . to work no matter what.

All these fail with the same error:

Could not find a version that satisfies the requirement private-pkg (from my-pkg==1.0.0) (form versions: ) No matching distribution found for private-pkg (from my-pkg==1.0.0)

Running it with pip install -vvv . shows that pip never looks for the git link, but running it with pip install --process-dependency-links -vvv . tries to fetch it but fails for various reasons ("Cannot look at git URL", or "Could not fetch URL"). Note that --process-dependency-links is marked as deprecated.

回答1:

pip expects to have a link to index page (such as PyPI) in dependency_links. Any link to VCS is going to be skipped. This behavior was changed in commit 26facdd.

I recommend to define all external dependencies in requirements.txt file and then run pip install -r requirements.txt. Example of requirements.txt:

foo>=1.0
-e git+ssh://git@github.com/private-org/private-pkg.git@master#egg=private-pkg

See also How to state in requirements.txt a direct github source

There is an article about setup.py vs requirements.txt, which describes this misfeature.
