nvim-completion-manager core channel terminated

[BooleanCat]

This issue has been talked about on Pivotal's internal slack, writing it up here for visibility for all.

What happened

I open vim and I see:

"~/workspace/bam-workstation/.git/COMMIT_EDITMSG" 66L, 1847C

Why

You upgraded Python 3.7. Since Python 3.7, async is a keyword. This means that nvim-completion-manager now has syntax errors.

Resolution

Workaround

I've worked around this for the time being by fixing the syntax errors:

sed -i.bu 's/async=True/**{"async": True}/' ~/.vim/plugged/nvim-completion-manager/pythonx/cm.py
sed -i.bu 's/async=True/**{"async": True}/' ~/.vim/plugged/nvim-completion-manager/pythonx/cm_core.py

You could also drop your python version to 3.6

Fix for:

Dark powered Vim/Neovim plugin manager :

sed -i.bu 's/async=True/**{"async": True}/' ~/.cache/dein/.cache/init.vim/.dein/pythonx/cm_core.py;
sed -i.bu 's/async=True/**{"async": True}/' ~/.cache/dein/.cache/.vimrc/.dein/pythonx/cm_core.py;
sed -i.bu 's/async=True/**{"async": True}/' ~/.cache/dein/repos/github.com/roxma/nvim-completion-manager/pythonx/cm_core.py;
sed -i.bu 's/async=True/**{"async": True}/' ~/.cache/dein/.cache/init.vim/.dein/pythonx/cm.py;
sed -i.bu 's/async=True/**{"async": True}/' ~/.cache/dein/.cache/.vimrc/.dein/pythonx/cm.py;
sed -i.bu 's/async=True/**{"async": True}/' ~/.cache/dein/repos/github.com/roxma/nvim-completion-manager/pythonx/cm.py;

For neovim users: those sed lines are:

sed -i.bu 's/async=True/**{"async": True}/' ~/.config/nvim/plugged/nvim-completion-manager/pythonx/cm.py
sed -i.bu 's/async=True/**{"async": True}/' ~/.config/nvim/plugged/nvim-completion-manager/pythonx/cm_core.py

[Daniel-Monroy]

He solucionado esto por el momento solucionando los errores de sintaxis:

sed -i.bu 's/async=True/**{"async": True}/' ~/.vim/plugged/nvim-completion-manager/pythonx/cm.py
sed -i.bu 's/async=True/**{"async": True}/' ~/.vim/plugged/nvim-completion-manager/pythonx/cm_core.py

También puedes bajar tu versión de Python a 3.6

Para usuarios de neovim: esas sedlíneas son:

sed -i.bu 's/async=True/**{"async": True}/' ~/.config/nvim/plugged/nvim-completion-manager/pythonx/cm.py
sed -i.bu 's/async=True/**{"async": True}/' ~/.config/nvim/plugged/nvim-completion-manager/pythonx/cm_core.py

Works in Ubuntu 20.04 !!! Thanks
