當我用 git 將代碼 clone 到本地之後，對代碼做了修改，然後輸入 git status 查看狀態時，報瞭如下錯誤：
fatal:
Not a git repository (or any of the parent directories)
原因：當前目錄下沒有.git 文件
解決方案：進入下一層目錄即可。
如：
$ git clone git://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts
Cloning into 'liggghts'...

$ git status
fatal: Not a git repository (or any of the parent directories): .git
$ cd liggghts/
$ git status
# On branch master
nothing to commit (working directory clean)
