Tried to build unique_identifier and ackermann_msgs on lunar.
Got this warning:
Warnings << unique_id:install /home/joq/ros/lunar_ws/logs/unique_id/build.install.001.log
/usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'install_requires'
warnings.warn(msg)
The setup.py in that package does specify install_requires, and distutils does not recognize that option. Removing that option eliminates the warning. When did that stop working?
Is install_requires no longer recommended?
