The problem is that I can't use python2 and python3 at the same time since I'm running it on Ubuntu (see the relevant discussion here). It looks like whenever I run vim, it is choosing python3. However every time I invoke vim I get a following message
DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
Press ENTER or type command to continue
This is python3 related. I'm sure the issue will be fixed later, but for now I just want to disable (not recompile) python3 support whenever I run vim. Is there a way to do it? Say something like vim --no-python3 myfile.txt
?
:help if-pyth.txt
and:help has-python
for what might be causing vim to pick one. The simplest thing to do is make sure you don't run any python code (which could come from a plugin) – D. Ben Knoble♦ Mar 2 '20 at 19:54
