第一步

克隆oh my zsh这个项目到本地

git clone git://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh

第二步

创建一个zsh的配置文件（注：如果之前已经存在，记得备份！）–非必须

 cp ~/.zshrc ~/.zshrc.orig

第三步

创建zsh的配置文件

 cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

第四步

设置zsh为你的默认的shell

chsh -s /bin/zsh

第五步

重新或新开一个终端测试，vscode或其他编辑器终端自行设置默认为zsh

注：idea命令行如果想使用oh my zsh,直接输入“zsh”就可以进入！

强迫症请看

[oh-my-zsh] For safety, we will not load completions from these directories until
[oh-my-zsh] you fix their permissions and ownership and restart zsh.
[oh-my-zsh] See the above list for directories with group or other writability.[oh-my-zsh] To fix your permissions you can do so by disabling
[oh-my-zsh] the write permission of "group" and "others" and making sure that the
[oh-my-zsh] owner of these directories is either root or your current user.
[oh-my-zsh] The following command may help:
[oh-my-zsh] compaudit | xargs chmod g-w,o-w[oh-my-zsh] If the above didn't help or you want to skip the verification of
[oh-my-zsh] insecure directories you can set the variable ZSH_DISABLE_COMPFIX to
[oh-my-zsh] "true" before oh-my-zsh is sourced in your zshrc file.

上面这类提示是因为权限不足造成解决方法如下

chmod 755 /usr/local/share/zsh
chmod 755 /usr/local/share/zsh/site-functions
