安装、配置iterm2中遇到的问题

步骤1

1、安装iterms2 链接地址
2、同时可以把字体也下载下来，后面会用到Meslo LG M Regular for Powerline.ttf

⚠️：下载Meslo字体的链接如下，Meslo字体是配合主题设置的是ZSH_THEME="agnoster"使用的。详细可以查网上，这个一般不会有什么问题的。

步骤2

1、安装oh-my-zsh 到~/.oh-my-zsh文件下

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

2、安装完oh-my-zsh后需要做的一件事是配置.zshrc文件，很重要，这一步花费了一些时间

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

步骤3

下载插件到桌面，或者直接找到位置然后下载。

1、下面是找到指定位置

cd  /Users/用户名/.oh-my-zsh/plugins

2、自动补充

 git clone https://github.com/zsh-users/zsh-autosuggestions

3、高亮

 git clone https://github.com/zsh-users/zsh-syntax-highlighting.git
2、把插件放到指定的位置，（**⚠️必须在/.oh-my-zsh/plugins文件夹下**）

问题一

注意⚠️如果使用git下载插件，不需要在～/.zshrc中配置一下代码，以下代码是使用homebrew下载安装才会增加的代码
1、使用git下载需要在~/.zshrc中配置到代码；可以在.zshrc中全局搜索plugins。

plugins=( git  
            zsh-autosuggestions 
            zsh-syntax-highlighting
            )

2、homebrew下载需要在~/.zshrc中配置的代码；

source /usr/local/share/zsh-autosuggestions/zsh-autosuggestions.zsh
source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

问题二

[oh-my-zsh] Insecure completion-dependent directories detected:
drwxrwxrwx 7 hans admin 238 2 9 10:13 /usr/local/share/zsh
drwxrwxrwx 6 hans admin 204 10 1 2017 /usr/local/share/zsh/site-functions

[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

解决方法

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

问题三
修改终端前面的用户名
前往～/.oh-my-zsh/themes/agnoster.zsh-theme文件夹下，打开agnoster.zsh-theme，全局搜索prompt_context()，定位代码做如下修改

# Context: user@hostname (who am I and where am I)
prompt_context() {
# 修改前
  # if [[ "$USERNAME" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
  #  prompt_segment black default "%(!.%{%F{yellow}%}.)%n@%m"
  # fi
  
# 修改后
 if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
   # 修改如下代码，@Mac可以你自己定义
   # prompt_segment black default "%(!.%{%F{yellow}%}.)$USER@%m"
   prompt_segment black default "%(!.%{%F{yellow}%}.)$USER@Fyn"
  fi
}
