This question has been asked several times around the site, but the answer frequently seems to be an omission of the install_requires arg.
Not the case here.

I'm trying to build a wheel that can be pip installed in a way that also installs a required package that's not on PyPI.

my setup.py includes: 

setup( install_requires= ['shotgun-api3'] dependency_links = [ "git+https://github.com/shotgunsoftware/[email protected]#egg=shotgun_api3" ], # ... )

From the commandline I then run python setup.py sdist bdist_wheel to generate the /dist/mypackage-0.1.0-py2-none-any.whl.

Rather than upload my package to an index, I'm trying to install my package from the filesystem; so in a clean virtualenv, I then run: pip -v install mypackage --no-index --find-links file:///F:/RyDev/myproject/dist --process-dependency-links.

And I get:

DistributionNotFound: No matching distribution found for shotgun-api3 (from mypackage)

and because I used the verbose flag, I see:

Collecting shotgun-api3 (from mypackage) 0 location(s) to search for versions of shotgun-api3: Skipping link file:///F:/RyDev/mypackage/dist/mypackage-4.0.0-py2-none-any.whl; wrong project name (not shotgun-api3) Skipping link file:///F:/RyDev/mypackage/dist/mypackage-4.0.0.tar.gz; wrong project name (not shotgun-api3)

It's maybe worth noting:

  • if I remove the install_requires arg from setup.py, mypackage will pip install without errors...just without the dependency.
  • I can run pip install git+https://github.com/shotgunsoftware/[email protected]#egg=shotgun_api3 and it successfully installs the shotgun-api3 package.

...but for the life of me, I can't seem to get shotgun-api3 to install as a dependency for mypackage.

It looks to me like the (git) URL I provided to dependency_links isn't being included in the list of locations, so I'm wondering if I'm missing something around that?

Environment:

  • Python 2.7.13 (cannot upgrade)
  • Windows 7 (cannot switch OS)
  • pip 10.0.1
  • setuptools 39.2.0
  • virtualenv 16.0.0
  • wheel 0.31.1

  • If I remember correctly, pip expects the package name in install_requires to match the egg name and link in dependency_links, so it must be smth like install_requires=['python-api'] and the dep link github.com/shotgunsoftware/[email protected]#egg=python-api. It will still install package named shotgun-api3 because the real name will be taken from the setup script. Commented May 24, 2018 at 13:01
  • You're right about the name match, but it looks like shotgun_api3 really is the name. I'd cloned the source and built the egg locally, and it generates shotgun_api3-3.0.36-py2.7.egg, so I'm thinking it must be something else? Commented May 24, 2018 at 16:09
  • ...again, the verbose output seems to indicate not that it can't find the package at the URL, but rather that it doesn't even look in the URL at all. Commented May 24, 2018 at 16:11
  • Did you ever find the solution for this? I am having the same issue right now: stackoverflow.com/questions/52735269/… Commented Oct 10, 2018 at 8:48

As for your setup.py:

In pip 19.0 and later, dependency_links is ignored. Use the PEP 508 syntax to specify the URLs to be used by pip:

setup( install_requires= ['shotgun-api3 @ git+https://github.com/shotgunsoftware/[email protected]#egg=shotgun_api3'] dependency_links = [ "git+https://github.com/shotgunsoftware/[email protected]#egg=shotgun_api3" ], # ... )

I've left your dependency_links in because nested dependencies in pip make use of setuptools, as discussed today in the comments of another StackOverflow question.

Regarding the installation:

Since I don't have your local packages it's not possible to check if this answer solves your problem. Be sure to remove the --process-dependency-links part when testing it though, because that is no longer supported in the latest pip either.

Alternatively, to install your local package, try pip install -e . instead of manually compiling and specifying everything.
