一种解决 oh-my-zsh 更新无效的方式

报错信息：

~ » upgrade_oh_my_zsh Upgrading Oh My Zsh Cannot pull with rebase: You have unstaged changes. Please commit or stash them. There was an error updating. Try again later?

解决方式：

I resolved it by:
1) cd ~/.oh-my-zsh/
2) git add .
3) git commit -m "commit message"
4) upgrade_oh_my_zsh

I reckon this happened as I added some custom plugins. All went smoothly :)
