fatal:
Unable to create '/.git/index.lock': File exists.
Another
git process seems to be running in this repository, e.g.
an
editor opened by 'git commit'. Please make sure all processes
are
terminated then try again. If it still fails, a git process
may
have crashed in this repository earlier:
remove
the file manually to continue.
要做的就是删除/.git/index.lock这个文件
