[Git] Git rename from index.lock to index failed.

前言

某天在機房 Commit 的時候一直頻繁下列訊息：

$ git commit -m "bug fixed"
Rename from '.git/index.lock' to '.git/index' failed. Should I try again? (y/n)...y
Rename from '.git/index.lock' to '.git/index' failed. Should I try again? (y/n)...y
Rename from '.git/index.lock' to '.git/index' failed. Should I try again? (y/n)...

詢問您是否要再嘗試一次，但...再怎麼嘗試情況都一樣!這怎麼一回事？

其實是因為...

權限的關係導致檔案無法被重新命名，此時你只要使用系統管理員權限開啟你所習慣使用的終端機，重新下指令即可。

原來這一切都是因為權限不足阿!
