1、推荐去官网下载，速度并不慢，网址：
https://flutter.io/setup-macos/
配置环境变量,这里笔者使用命令行：
vim ~/.bash_profile
添加环境配置
export PATH=/你的flutter文件夹所在位置/flutter/bin:$PATH
保存一下，注意如果这个文件不存在，那么就新建一个。保存完毕之后运行命令:
source ~/.bash_profile
这个时候应该能运行flutter命令了，我们运行命令行：
flutter -h
看起来是如此的简单：但是坑还是很多的
坑1、.bash_profile文件根本不存在 创建一个
touch .bash_profile
添加如下配置
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=/Users/ruihe/Downloads/flutter/bin:$PATH
坑2、
MacBook-Pro:~ xxxx$ flutter -h
-bash: flutter: command not found
下载下来之后把文件复制到其它里面去了 运行source ~/.bash_profile一直抱这个错，纠结了好久，最后重新下载了一根直接把这个下载的路径/Users/xxxx/Downloads/设置了进去，
xxxxxx$ open ~/.bash_profile
xxxxxx$ source .bash_profile
xxxxxx$ source ~/.bash_profile
主要不知道2和3那个是对的，所以一起运行了一下
坑3、
$ flutter doctor
