Error starting margo

[jdelk]

I switched to the development build of GoSublime and reinstalled it. Now I'm getting this error:

--------------------------------

SublimeText version is 3.2.2 (Build 3211) , Go version is 1.13.4 and Python version is 2.7.17

I've tried reinstalling GoSublime several times but I'm still getting the same error.

@jdelk What version of Windows are you using, maybe I Microsoft supplies a VM I can use to reproduce this. Subime Text ships with its own version of Python so I don't think it's related to the one you have installed.
