coc-python gives no completions ever

[jsholmes]

coc-python always times out.

I do see this in my log when trying to investigate.

2020-04-23T15:22:33.246 ERROR (pid:23697) [watchman] - Error: unable to resolve root /mnt/harmonix_vol2/soporifix_vol3/user/home/john: path uses the "nfs" filesystem and is disallowed by global config illegal_fstypes: relocate the dir to an allowed filesystem type

  }
}```

Do I need to tell the python extension to use some other path for its work somehow?

I've determined that it doesn't work if I'm in this workspace root, which is my actual project:

## versions

But does if I'm in this one, which is just a tmp dir:

[Info  - 3:41:18 PM] subscribing "*/*/python" in /usr/scratch/tmp

So I guess the only difference there is that in the working one, I see these lines after User search paths:

I think I've narrowed down the issue to this: microsoft/python-language-server#181

I tried building a local copy of MPLS to fix it, but when I copied the output dir over to what coc was using, it no longer worked. :(. I did notice lots of dlls were missing from the output dir. Is there something I have to do to get it to build everything I need for a full packaging?

New issue in mpls for this: microsoft/python-language-server#2006
