Iterm2是Mac下非常好用的一款终端软件，具有高度的可配置性，本文为结合oh-my-sh一步步打造一个让你爱上终端的主题。效果图如下：
效果图
本文不对如何安装iterm2和oh-my-sh的安装进行详细介绍，这里给出两篇比较详细的安装配置文章
Terinmal整容日记以及iTerm2 + Oh My Zsh 打造舒适终端体验，按照任意一个教程进行详细操作后再继续下面的配置都可以达到文章开头的效果图，所以不用担心会误操作，下面主要解决安装过程中遇到的一些奇怪的问题；
1.字体错误问题
关于字体乱码或显示不全的问题可以参考上面的第二篇文章进行字体的安装，安装完成后再iterm2的首选项里进行字体的选择，基本就可以正常显示了。
2. 每次打开终端都要source ~/.zshrc才能让主题生效的问题
这个问题涉及到终端打开时配置文件的执行顺序，这里通过以下几步进行解决
首先打开终端配置文件
open ~/.zshrc
在配置文件中添加如下两句，如果你已经定义过了，请保证顺序和下面一致。
source $ZSH/oh-my-zsh.sh
source ~/.bash_profile
保存文件，在终端中使其生效
source ~/.zshrc
3.在vscode中显示乱码
这一部分在链接第二篇文章的末尾有解决方案，这里就不在说了。
最后放出本文终端的配置文件 ~/.zshrc，如果喜欢可以直接替换自己的配置文件，就可以有如上效果
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH

# Standard plugins can be found in ~/.oh-my-zsh/plugins/*
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
