Description

Originally reported by: dirk-thomas (Bitbucket: dirk-thomas, GitHub: dirk-thomas)


When passing egg_info --egg-base SOMEPATH additionally to setup.py develop the egg file is created in that location. This is done to build out-of-source and not drop any artifacts in the source folder of the package.

But it always fails with the following exception: https://bitbucket.org/pypa/setuptools/src/18eceee63709bc70c06b51a609f3dbd2eab07ef4/setuptools/command/develop.py?at=default#cl-84

It seems like there is no way to parameterize the invocation with --build-directory, --egg-path which would be valid.

Research direction

Start in setuptools/command/develop.py at the failing invocation linked in the issue, then trace how setup.py develop passes egg_info --egg-base SOMEPATH. Reproduce the out-of-source case and verify that setup.py develop succeeds without placing artifacts in the source folder.
