Cannot startup jedi server

[Joxos]

When I open a python source file, the jedi failed.
I tried to do this:

pip install jedi-language-server

But it still cannot working.
These are my :CocInfo messages

Question: is jedi-language-server in your path? Eg, when you type jedi-language-server in your terminal, does it appear to run?

I ask because, on Windows, the error code ENOENT means something like "no such file or directory". See here. This implies that, despite having pip installed jedi-language-server, the executable itself isn't in your path.

My recommendation: figure out the full path to the jedi-language-server executable on your system and put the full path in your coc-settings.json like this:

"jedi.executable.command": "D:\\path\\to\\jedi-language-server",

Note: I haven't used Windows in years, so I'm guessing how to resolve your issue based on some Google Searches and my memories of Windows 7. That said, I'd definitely like to support Windows well, so I appreciate you opening this issue!

Note: you might need double \\ to escape the backslash in JSON

[Joxos]

I've already tried that, but it's still not working.

[Joxos]

I've tried the "jedi.executable.command" and it worked!
Thanks a lot!

[Samuel Roeca]

Amazing, what did you try end up putting as your the executable path? I'd like coc-jedi to better-support windows out of the box, so if there's anything you can teach me about your setup I'd be grateful!

Hi, really appreciate your work. Just want to add: please list python3-venv as a dependency on this extension. I've recently been moving to vim, and getting this to work took me an hour because I didn't realise I had to install this.

Thanks for the great work!
