How to make a Catkin_ws using anaconda?

asked 2020-03-09 06:10:00 -0500

Im having an issue using the Catkin_make function when using anaconda.

I tried installing ROS-melodic desktop full and follow the installation guide and setup of the catkin_ws when using python as on the official site. However it says that it can't locate the package "catkin_pkg".

I then tried updating, installing it getting it any way i can. It seems to me that either catkin_pkg can't be found by anaconda or something. I also tried uninstalling ROS, creating an ananconda enviroment for ROS, then installing ROS there and following all the same steps. Again same error.

I made sure i got the correct path and all, the PYTHON path. which was in my env folder, then bin.

(py37ROS) ~ cd catkin_ws

Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.

(py37ROS) catkin_ws 

And then it says that catkin doesn't get installed or updated because of a missing dependency. Althought i have installed it.

(base) ~ conda activate py37ROS
(py37ROS) ~ sudo apt-get install python-catkin-pkg
