vsk run examples/quick_draw gives TypeError: 'NoneType' object is not callable

[mansi-aggarwal-2504]

I am following all steps but getting this error when I run vsk run examples/quick_draw:

try pip install -U click

[mansi-aggarwal-2504]

I am now getting this error:
ModuleNotFoundError: No module named 'click._bashcomplete'

Probably because there was an error while pip install -U click:

ERROR: vpype 1.7.0a0 has requirement setuptools<52.0.0,>=51.0.0, but you'll have setuptools 41.2.0 which is incompatible.
ERROR: typer 0.3.2 has requirement click<7.2.0,>=7.1.1, but you'll have click 8.0.1 which is incompatible.

Guess there are internal compatibility issues?

[abey79]

It looks like typer is not yet compatible with click 8 (tiangolo/typer#278). Hopefully they will address this rapidly. If not, I'll have to remove typer in favour of click.

In the mean time, you may fix the issue by forcing vpype to 1.6.0:

pip install -U vpype==1.6.0

[mansi-aggarwal-2504]

I did that and the errors have gone. But when I run my project, and I can only see a python process running but the window doesn't open. What might be the cause for this?

[abey79]

You may check if pip install -U git+https://github.com/abey79/vsketch@fix-no-typer#egg=vsketch fixes the issue.

[mansi-aggarwal-2504]

It didn't work. Same issue

[tiangolo]

I just released Typer 0.4.0, which is compatible with both Click 7 and Click 8. 🎉
