Robotpy init not working

Technical Python
1

I’m trying to setup our robotpy project. When I run it I get a banner and no errors but the directory remains empty. What am I doing wrong?

Kyles-MBP-2:src kyle$ python3 -m robotpy init

                                                  /PPPPPPPPPPYYYYYYYYYY\

                                                /PPPPPPPPPPPPYYYYYYYYYYYY\

This keeps coming up, I need to update the docs, sorry. There’s some weird bug with pip. Do python3 -m pip uninstall robotpy followed by python3 -m pip install robotpy and the logo will go away.

Edit: Ok, I documented it now

Well I tried that and noticed it was removing a 2023 version and then I realized I didn’t have my virtualenv activated. So I did it again with it active. I get and error this time.

I’ve definitely seen someone with that error… but it works on my mac at the moment, so we must have fixed it. What package versions do you have? I would ensure you’re on 2024.1.1.3.

Okay, I think I figured it out. Installing commands-v2 downgraded all the core robotpy packages. I blew away the venv and started over. After only installing robotpy the init worked. I then installed commands-v2 and noticed all the robotpy packages were downgraded to a 2023 version.

I saw something about commands not being ready yet but I thought I saw a follow-up about being able to use an older version.

You need to install robotpy-commands-v2==2024.0.0b4. The 2023 version will cause problems, as you can see.

Got it. I didn’t realize how pip handled beta versions. I assumed it always installed the newest. Appears we are good to go now.

Thank you for you prompt support!!
