1、创建一个路径。例如我创建是：

/Users/chenghui/

然后创建一个文件夹：

development

把下载好的Fluter 解压到当前目录下： development

/Users/chenghui/development

2、当你看官网的时候，Mac环境配置 许多小伙伴都是卡在了配置环境变量这里。

基本我们都要创建一个 .zshrc文件，默认情况下不存在。

创建步骤：

1、开放终端
键入
touch ~/.zshrc 以创建相应的文件。（该touch 命令将在当前目录中创建.zshrc，但它将被隐藏）

击中 return
2、要查看/打开，~/.zshrc您可以执行以下两项操作之一：

2.1、打开查找器 => 按 Cmd + Shift + .    (显示或隐藏文件，不要随便删除这些隐藏文件)
============ OR ====================

2.2、打开终端 => 类型 open ~/.zshrc

3、配置永久路径
但你打开 open ~/.zshrc

// 默认是这样子的：
export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin"

把 [PATH_TO_FLUTTER_GIT_DIRECTORY] 替换成你自己的目录路径。

这里我的是：/Users/chenghui/development

export PATH="$PATH:/Users/chenghui/development/flutter/bin"

输入后 ~等待~~ 回车的效果：

chenghui@chenghuideMacBook-Pro-2 development % open ~/.zshrc
chenghui@chenghuideMacBook-Pro-2 development % source $HOME/.bash_profile
[Chenghui-\u \W]$ echo $PATH

/Users/chenghui/.rbenv/shims:/Users/chenghui/.rbenv/bin:/usr/local/opt/openssl/bin:/Users/chenghui/.rbenv/shims:/Users/chenghui/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Users/chenghui/.rvm/bin:/Users/chenghui/flutter/bin:/Users/chenghui/development/flutter/bin
[Chenghui-\u \W]$

如果选择了：(开发二进制文件预下载（可选操作）)~~~ 等待…..

[Chenghui-\u \W]$ flutter precache

继续等待....

Downloading Android Maven dependencies...
(This is taking an unexpectedly long time.)       ⣾

最终下载是这样子吧：

  272.6s (!)

接着，查看当前是否还要安装其他依赖：flutter doctor

[Chenghui-\u \W]$ flutter doctor

[Chenghui-\u \W]$

它说我的Android Studio 和 IntelliJ IDEA Ultimate Edition 没有安装插件。但是Xcode 和 VS Code 是可以的。

4、Xcode 和 Android Studio 的安装基本跟着官网就可以了…… 忽略！！！

5、使用终端创建一个应用：

[Chenghui-\u \W]$ flutter create my_app

又是漫长的等待…. This is taking an unexpectedly long time.

 $ cd my_app
  $ flutter run
