here is the error. Did you try to see 2 link I give to you?

It's not likely caused by coc.nvim itself since it has nothing to do with your python. Should be python issue with your vim, try uninstall coc-snippets which using python code or use let $COC_NO_PLUGINS = '1' in your vimrc to disable all extensions of coc.nvim.

[chemzqm]

Use command like :pyx print(3) should reproduce the issue.

This work to me, no error show after use let $COC_NO_PLUGINS = '1'. But :pyx print(3) still raise the error. So what's happening in here? It's caused by vim?

@hungpham3112 In coc-snippets, there is code that uses :pyx because of its ability to work with Ultisnips, so it will cause an error, but your Vim8 is causing the error with the :pyx command in the first place.

Another Vim plugin that uses :pyx will probably give you the same error

This is not a problem with coc-snippets.

I don't use Windows, so I don't know, but if you install vim and python in a way other than scoop, for example, you might be able to isolate the problem!

[chemzqm]

Compile your vim with python you've just installed should help.

I was able to work around this problem by setting the PYTHONHOME environment variable, like so (on cmd, adapt for poweshell etc):

set PYTHONHOME=C:\Users\giovanni\scoop\apps\python39\current\ 

I'm not sure why this is happening, but it fixed it for now.

I'm on the same setup, vim and python installed through scoop. I got the exact same error.

The :pyx print(3) was a good test, it crashed immediately with the same error. The let $COC_NO_PLUGINS = '1' also fixed it temporarily, so I could run vim without issues and test the waters.

See this, It's cause by the sample vimrc and gvimrc in directory when you install vim. Solved here
