- .从gitthub拉取代码：

git clone -b beta https://github.com/flutter/flutter.git

- 配置环境变量：

在当期用户目录下创建.bash_profile文件，如果该文件已经存在， 则直接打开。将以下代码复制到.bash_profile中，

    export PATH_TO_FLUTTER_GIT_DIRECTORY=/Users/你的用户

    名/flutterexport PATH=${PATH}:$

  {PATH_TO_FLUTTER_GIT_DIRECTORY}/bin

完成之后点击保存，在命令行中执行source  .bash_profile，

然后输入flutter 进行测试。没有出现commond not found

即是配置成功。

-  执行命令flutter doctor ，命令的作用是检测还需要安装的依赖。
