Many errors after installing

[vitaly-zdanevich]

In README is not mentioned default plugin manager in Vim 8 - I just cloned the repo into ~/.vim/pack/git-submodules-plugins/start

I see red errors:

Yes, I tried minimal .vimrc configuraion with only autocmd FileType java setlocal omnifunc=javacomplete#Complete - with that I have nothing, no completion.

It seems like some issue with your python installation. It cannot do import _socket.

[vitaly-zdanevich]

The second Python is stock on macOS.

[artur-shaik]

Try to run python console and execute this command: import socket or this: import _socket.

[vitaly-zdanevich]

[artur-shaik]

What if you do it in vim: :python import _socket ?

So yes, you have some issue with your python and you should fix it. When I run this command, it just executes without ImportError and other output.
