Git报错：Another git process seems to be running in this repository

#事故现场

Git操作的时候突然报错：

Unable to create ‘D:/xxx/.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.
Pull operation failed.

翻译：另一个git进程似乎正在这个存储库中运行，例如 由“git commit”打开的编辑器。请确保所有流程终止，然后重试。如果它仍然失败，一个git进程可能已在此存储库中崩溃：手动删除文件以继续。

#原因分析
方法一：找到.git/index.lock文件，直接删除即可；
如果在linux上的话，执行rm删除命令：

rm -f .git/index.lock

方法二：执行git命令

git clean -f .git/index.lock

方法三：自己去目录删除这个文件
