Configure install to use local projects

[mforkel]

• Pip version: 9.0.1
• Python version: 2.7.14
• Operating system: Ubuntu 17.10

Description:

I'm using local projects, i.e. non-VCS "editable" installs, in virtual environments during development.

There does not seem to be an option similar to --find-links for configuring pip install to use those local projects to fulfill requirements. I think there are at least two use cases:

• Overriding distributions with local development versions and
• fulfilling recursive requirements of local projects during install.

@mforkel What are you trying to achieve here? It's unclear from the description to me.

[mforkel]

Thanks for looking a my issue.

I'm working on multiple interdependent Python packages in parallel. During development, I would like to be able to specify in pip.conf (or on the command line, for that matter) where these packages can be found - basically a path of the directory containing setup.py. That would allow me to create a virtual environment, pip install -e one of my packages and have pip fulfill some of its requirements by creating editable installs for some of the other packages in development. Note that I don't want to perform a snapshot and install a clone captured in an archive.

The packages specified as local editable installs should overide packages available from (local) PyPI-like repositories, depending on the development and the archiv version..

This is related to #5031.

Is there some reason you can't specify the packages in a requirements.txt and install them?

[mforkel]

I don't want to install all packages I'm working on in each virtual environment. I would like pip to know where to find packages under development, so I can install one of them and have pip resolve its requirements, using development versions where available (and appropriate, depending on the version numbers). The requirements should only be listed int the setup files.

This sounds like a pretty specialised situation, and as far as I can tell from your description, it would be quite complex to implement. I'm inclined to say that it's not sufficiently general to be something we'd want to add code specifically to support.

If you can more precisely specify what changes you'd like to see in pip, and provide some indication that the workflows that these changes would enable would benefit enough pip users to warrant the changes (i.e. it's not just you that works like this :-)) then we can reconsider the proposal.

+1 to what @pfmoore said. @mforkel Ping?

Closing due to lack of response.
