Flymake immediately crashing on all new Python files opened #1859

Open awood45 opened 3 years ago

awood45 commented 3 years ago

Summary

Whenever I open a new Python file, I get the following error:

Flymake: Configuration error has occurred while running (black /PATH/TO/MY/PROJECT/setup_flymake.py). Flymake will be switched OFF > OK

The black part doesn't seem to matter, if I disable '(elpy-syntax-check-command "black") all other syntax checkers will fail with the exact same message.

The *Messages* buffer also shows the following messages preceding this failure:

Making python-shell-interpreter local to  *Python Internal [d78b2acce95628d9b2610290347a0f95]* while let-bound!
Making python-shell-interpreter-args local to  *Python Internal [d78b2acce95628d9b2610290347a0f95]* while let-bound!

Steps to reproduce

In my case, any time I open up a Python file. I have another laptop where this doesn't seem to happen, including on the same projects, but I haven't quite been able to divine the material difference yet.

I apologize if I am stating the obvious, but I think you need to make sure your config is setup. You don't have anything installed in your elpy-config. Maybe Flymake depends on these? This should get prompted when you create/open a python file. Not sure why it's not...

But I'm still Elpy/Emacs noob and your config file makes me think you know what you're doing. So sorry if my comment isn't all that helpful. :/

It's not outside the realm of possibility that I've misconfigured something, though I don't think that's the cause here:

whompyjaw commented 3 years ago

Sorry, I should have elaborated on what I meant by "prompted". IIRC, when I saved a python file (or when I called M-x elpy-config), the RPC process began installing all the necessary sub packages (as listed in elpy-config), and everything gets installed. Sadly, I can't remember if this happened when I saved a python file or when I called elpy-config

This is my elpy-config result.
