git reset --hard xxx_gitTag遇到的一些问题解决方法

 

GIT: /.git/index.lock': File exists

 

fatal: Unable to create '/.git/index.lock': File exists

 

解决方法：

Try

rm -f ./.git/index.lock

In your repository directory.

 

===================================

Unlink of file failed

Unlink of file 'xxx/xxx/xxx.xx' failed. Should I try again? (y/n) y

That usually means a process is still using that specific file (still has an handle on it)
(on Windows, ProcessExplorer is good at tracking that kind of process)

 

解决方法：关掉你的VS2008等IDE。

===================================

 

error: git checkout-index: unable to create file (Permission denied)

 

error: unable to create file xxx/xxx/release/emulator/bin/Loader.log (Permission denied)
fatal: Could not reset index file to revision 'c6e028341caa8d72ab407d69e63a6503e69d84ae'.

上面链接说的都是权限问题，但是不要被这个提示误导了。我的实际上是一个loader.exe在打开，关闭就好了。

$ git reset --hard xxx_gitTag(也就是git log下显示的commit后面跟的commitId)
HEAD is now at c6e0283 Merge MR-255 from branch 'somebody/xxx_project.git::master' into 'master'

解决方法：关掉某个运行的exe，它可能正在占用某个文件。
