Git checkout: updating paths is incompatible with switching branches
https://stackoverflow.com/questions/945654/git-checkout-updating-paths-is-incompatible-with-switching-branches
简介：
I believe this occurs when you are trying to checkout a remote branch that your local git repo is not aware of yet. Try:
$ git remote show origin
If the remote branch you want to checkout is under "New remote branches" and not "Tracked remote branches" then you need to fetch them first:
$ git remote update
$ git fetch
Now it should work:
$ git checkout -b local-name origin/remote-name

简介：
$ git fetch
$ git checkout -b develop origin/develop
