The following error occurs, autocompletion not working:

[ncm2_jedi@yarp] AttributeError: module 'jedi' has no attribute 'Script'

Plug 'ncm2/ncm2-jedi'

A solution that worked:

Reinstall jedi in the host python3 (g:python3_host_prog) via pip, and the error is gone. Not sure why module jedi had pointed to a wrong (maybe old) version previously.

Unfortunately it is documented nowhere and error handling seems not robust. For example, we may detect jedi is well installed and import-able using the host python3 interpreter, and warn users if not.

Any other thoughts how we can improve this, as many users might experience this error?

I got the same error, and solved it by installing jedi into the python3 virtualenv I set up for neovim.

Hello @wookayin and @cbcoutinho, I wanted to write and let you know that I recently ran into this issue. I am currently running NVIM v0.3.2-dev on Ubuntu 16.04 and found that I also had to upgrade my installed version of jedi. After I did that, I found that ncm2 and ncm2-jedi worked correctly. Perhaps it would be a good idea if there was some documentation to indicate which version of jedi was supported?
