Using setuptools generates egg-info folders in source space when installing

[matthew-reynolds]

Continuing the conversation from #1048 (comment). Using setuptools, as is now recommended:

egg-info folders are created in the source space when building Melodic packages w/ python 2 on Bionic. This seems to only happen when installing (ie. catkin_make install). (See https://travis-ci.org/github/ros-controls/ros_control/jobs/661982516?utm_medium=notification&utm_source=github_status)

Steps to reproduce:

cd /tmp
mkdir -p mel_ws/src
cd mel_ws/src
git clone [email protected]:ros/angles.git
chmod a-w -R angles
cd /tmp/mel_ws
catkin config --install; catkin build         # Fails
catkin clean
catkin_make install                           # Fails
catkin_make_isolated --install                # Fails

Oh, it's a Py2 issue—that might explain why I'm not hitting it as we're now migrated.

What setuptools version are you using (pip freeze --all | grep setuptools)?

What setuptools version are you using (pip freeze --all | grep setuptools)?

I'm able to reproduce with setuptools==39.0.1

[matthew-reynolds]

What setuptools version are you using (pip freeze --all | grep setuptools)?

I'm using setuptools==41.0.1. Not sure what version the Travis build I linked used though.

Edit: I can still reproduce the issue with setuptools=44.0.0, which AFAIK is the latest version that is Py2.7 compatible.

Addressed in #1073.
