git遇到的问题-- Another git process seems to be running in this repository

Posted 2021-01-13 fancylee

执行git add .时，报错

fatal: Unable to create ‘/Users/lily/ForWork/forReBaomai/bm-fe/.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.

大致意思是说：在/Users/lily/ForWork/forReBaomai/bm-fe/.git里创建index.lock失败：文件已存在。git的进程已经在一个编辑器中被打开。请确保所有的进程都结束，然后再次尝试。如果仍然失败，可能是上个运行中的git崩溃，手动移除这个文件

解决方法：open /Users/lily/ForWork/forReBaomai/bm-fe/.git 打开.git文件夹，删除该文件下的.git文件即可

　　　　或者 rm -f ./.git/index.lock

原因：据说是计算机对于进程的同步互斥管理，是有资源上锁机制的。猜测这里肯定是有进程对某资源进行了加锁，但是由于进程突然崩溃，未来得及解锁，导致其他进程访问不了

查了半天只查到这么一个原因，所有文章都只有这么一个解释，暂时记着吧
