changes would overwritten by merge

现象：git pull出错：

xxxMacBook-Pro:xxx minglong$ git pull

Aborting

原因：本地有更新，但是没提交。而pull下载并合并，会把本地改动覆盖掉。

解决办法：把本地的暂存起来，再去pull更新并合并，再把暂存的恢复出来。

操作步骤：

git stash

git pull

git stash pop

补充：

另外也遇到一个类似情况，但是处理方式是：

扔掉另外2个冲突的，但是无用的文件：

git checkout — file_you_want_throw_away

再去git stash pop即可：
