修正在MAC OS X下git commit时vim的editor error

8th April 2010
I have had an annoying problem with git and vi. I like to use vim to edit my commit messages, but I’ve been hit with this annoying message every time I write the message and quit vim.
error: There was a problem with the editor 'vi'
After a little bit of digging I found that this message is shown by git when the editor exits with a non-zero exit code. You can use $? to see the exit code of last script or application.
$ vim     # then exit vim with :q immediately
$ echo $?
1
I’m still not sure why vim is exiting with non-zero exit code, but it is definitely related to my .vimrc - moving it to .vimrc.bak seemed to fix the problem. I’m using the excellent  plugin to manage my vimfiles, so I plan to go through that and my installed plugins to find the cause of the problem.
There is a fix though, I’m not sure what’s causing this, but I found a  which shows this:
$ vim          # and exit with :q
$ echo $?
1
$ /usr/bin/vim # and exit with :q
$ echo $?
0
$ which vim
/usr/bin/vim
Running vim with /usr/bin/vim seems to make it exit cleanly. So to fix the problem with git commit you just need to run this:
$ git config --global core.editor /usr/bin/vim
I’d still like to get to the root of the problem, but this gets me my git commit messages back!
