python 3 installed over 2.7, incompatability with existing programs
When I was first only using ROS on this computer I had projects working nice. Over the weekend I installed Python 3.6.9 for a python project, and ROS has been messed up.
Upon writing python --version OR python3 --version, I see:
Python 3.6.9
There are also problems with pip.. pip --version and pip3 --version yields:
pip 20.1.1 from /home/daniel/.local/lib/python3.6/site-packages/pip (python 3.6)
Errors also arise when calling ROS nodes, from the python 2.7 folder... As installing python was the only thing that changed I'm guessing/hoping there is only some redirecting to do.
I think I installed python3 and pip3 over the originals, somehow. Any advice on how to reverse this? Thank you!
This probably isn't going to help in your current situation, but I use pyenv to manage different versions of Python and the pyenv-virtualenv plugin to manage virtual environments. Together, these make it incredibly easy to work with different versions of Python
