Completion popup menu not appearing about nvim-completion-manager HOT 20 CLOSED

Could you follow the trouble shooting section in READNE.md and provide the log of cm_core?

from nvim-completion-manager.

I ran in my shell:

NVIM_PYTHON_LOG_FILE=nvim.log NVIM_NCM_LOG_LEVEL=DEBUG NVIM_NCM_MULTI_THREAD=0 nvim bla.py
But nothing was generated in my working directory. Did I forget a step?

from nvim-completion-manager.

If no log file is generated, you need to start NCM manually and see what's happening, You could still follow the steps in the trouble-shooting section.

Apologies for the probably simple questions - I'm relatively new to using vim. I was not able to start NCM manually. I ran

:echo neovim_rpc#serveraddr()
From within vim and the terminal and got this error

from nvim-completion-manager.

NVIM_PYTHON_LOG_FILE=nvim.log NVIM_NCM_LOG_LEVEL=DEBUG NVIM_NCM_MULTI_THREAD=0 nvim bla.py It seems you're using neovim instead of vim8, in this case you need :echo v:servername instead of :echo neovim_rpc#serveraddr()

If you are using vim8, then the error you provided should be the cause of this issue.

Looks like the vim-hug-neovim-rpc fails to execute both :python3 import neovim_rpc_server and :python import neovim_rpc_server. You could check that manually.

Also make sure the pythonx directory of vim-hug-neovim-rpc is in the installation directory.

from nvim-completion-manager.

It says there is "No module named neovim_rpc_server" when I ran the latter command. I double checked to ensure my vim version has python as well.

The pythonx directory is in .vim/bundle/vim-hug-neovim-rpc/; I installed the plugins with Vundle.

from nvim-completion-manager.

If vim failed to execute both :python3 import neovim_rpc_server and :python import neovim_rpc_server.

Use :echo globpath(&rtp,'pythonx/neovim_rpc_server.py',1) to check the installation of vim-hug-neovim-rpc. If the result is empty, then vim-hug-neovim-rpc is somehow not properly installed. Something wrong with rtp maybe.

This is really wierd. Vim did successfully load the autoload function, but the python fails to search the pythonx directory.

:help pythonx may give you some useful information.

from nvim-completion-manager.

Maybe there's some other error going on.

Remove NCM, leave vim-hug-neovim-rpc installed alone.

Then execute :python import neovim_rpc_server and check the error message.

from nvim-completion-manager.

I get the same "No module named neovim_rpc_server" error with just vim-hug-neovim-rpc installed.

from nvim-completion-manager.

Also make sure vim can successfully execute :python import neovim, this is a new dependency added in recent updates.

from nvim-completion-manager.

I think this is it, vim also reports "No module named neovim_rpc_server" when dependency is not satisfied.

I'll add some verbose information when this error uccor, thanks for your information.

Vim seems not to choose the python installed via homebrew,

this might be useful: http://vi.stackexchange.com/questions/6604/how-to-access-a-custom-python-module-inside-vim

from nvim-completion-manager.

I guess that execute pip install neovim for your system wide python instead of the one installed via home-brew, would fix this error.

from nvim-completion-manager.

It works now! Thank you so much for your help.
