chsh: no changes made 错误解决方案
前提纪要：
1、我们都知道mac有默认bash工具，在下载zsh后，把一切都配置好后，输入切换命令：
chsh - s /bin/zsh ,总是提示 chsh: no changes made错误。那我我们尝试用sudo chsh -s /bin/zsh 在试一次。如果还是不行，就不用再弄了，直接用下面的方法吧！
提示chsh:no changes made 解决办法：终端输入：
dscl . -read /Users/$USER/ UserShell
exec su - $USER
然后在输入密码即可。完美解决
下载此插件：
$ wget http://mimosa-pudica.net/src/incr-0.2.zsh
将此插件放到oh-my-zsh目录的插件库下：
# root @ linux in ~/.oh-my-zsh/plugins/incr on git:master x [15:05:07]
$ ls root@linux
incr-0.2.zsh
在~/.zshrc文件末尾加上
source ~/.oh-my-zsh/plugins/incr/incr*.zsh
更新配置：
$ source ~/.zshrc
接下来你就可以体验到Your terminal never felt this good before...
