Edited to fix typos…
Sorry to bump an old one, but maybe this will help some people. This worked for me, not sure if it’s the best solution or will work for everybody.
The environment variable is set in Julia with:
julia> ENV["JULIA_PKG_USE_CLI_GIT"]=true
If you want this behavior always (which I think many do), then you need to put this in a startup.jl file. If you don’t have one of those already, it goes here:
C:\\Users\\you\\.julia\\config\\startup.jl
and just put that one line in the file.
