MacVim + Anaconda Python3 support

[Richard Randolph]

I’m learning VIM and Python, novice for both. I would like to use VIM as a Python editor and I’d like to run python directly from the VIM editor. I use Anaconda for my python install. I built VIM from source so I could be sure VIM uses Anaconda instead of the system python. After I built VIM it appears to be working and using the Anaconda install but :version shows ‘-python3’ (thought it should be ‘+python3’). Being a total novice to python, VIM, unix, etc., I’m not sure if I have VIM installed properly.

Also, I was wondering the best way to run python from VIM. Is there a better way than typing ‘:w !python’?

I download the source code from GitHub.
https://github.com/macvim-dev/macvim/releases/tag/snapshot-116
macvim-snapshot-116.tar
I followed instructions for building on a MAC.
https://github.com/macvim-dev/macvim/blob/master/READMEdir/README_mac.txt
 
Run `./configure` in the `src/` directory with the flags you want to call
 
$ cd src
./configure --with-features=huge \
--enable-python3interp=yes \
--with-python3-config-dir=/Applications/Anaconda/anaconda/bin/python \
--enable-cscope
 
Now build the project using `make`:
 
$ make
 
To install MacVim, type
 
$ open MacVim/build/Release
 
and drag the MacVim icon into your `Applications` folder.

However, when I check version I see that I don’t have python3 support.

I can run python from VIM.

print ('Hello World!')
~
~
:w !python
Hello World!

And the version does point to the Anaconda install.

import sys
print (sys.version)
~
~
:w !python
