Hello, so im trying to install Robotpy CTRE 2017 library with the following command


pip3 install roborio-ctre*.whl

and i get the error


pip3 command not found

does anyone else have this issue and know how to resolve it?

thank you for your time

Where are you executing the command? It should be executed on the RoboRIO.

Do you have RobotPy installed? It won’t work if RobotPy is not installed.

the command is being run ssh’ed into the roborio with winscp with robotpy 2017.0.3 installed

i decided to use PuTTY ( a software im more comfortable with) and i get the new following error

What user did you log in as? You need to login as admin (not mentioned in the install instructions… but hopefully will get the installer upgraded soon so you won’t need to deal with this anymore).

An installer-based approach is now available. See https://github.com/robotpy/robotpy-ctre for details
