I had a
~/.vimrc with some basic syntax highlighting that was working fine until I upgraded to Catalina. Running
vim -V I see it loads my vimrc but it totally ignores anything in it. If I run
:so ~/.vimrc inside vim it also ignores it, but if I run the commands from the vimrc one by one then it accepts them.
How do I get vim to source my vimrc again?
