rvctool: command not found

[MorphRobotics]

After running pip install rvc3python. The rvctool command does not work, it returns the error "rvctool: command not found"

[petercorke]

are you working inside a virtual environment like conda? Did you try rehash?

this probably should have been reported as a bug rather than errata, it's an issue with the code not the book.

[petercorke]

resolved?

[MorphRobotics]

Not yet, I've attached a picture of the error I'm getting. To use the toolbox I have to go into iPython and manually code in that environment.

[petercorke]

ok, this looks an error in the spatial math library related to type hints that is occurring for Python 3.10. Leave this with me.

[petercorke]

Do you have the latest version of typing_extensions installed in this python environment?

[MorphRobotics]

Yes I do

I have came across with a similar problem in rtbtool yesterday, uninstalling and reinstalling matplotlib solved my issue, I hope it would help with your case as well.

Hi @followthwhiterabbit, rtbtool was the precursor to rvctool, same principles but I suspect it might be a bit buggier. It's roughly equivalent to rvctool --no-vision. Not sure why changes to matplotlib would have the effect you mentioned, that seems odd.

I've just done a clean install using conda for Python 3.10, on a Mac, and got no issues. If you still have no luck, are you willing to try it with conda? I resisted conda for ages, but it's made my life so much easier.

I also encountered the same problem
