在macOS上搭建Flutter开发环境--菜鸟
安装环境
你好！ 这是第一次使用 Flutter ，准备学习下。刚开始看Flutter中文版网站步骤，边百度学习参考Flutter 安装 (Mac环境)1。
1. 打开终端。克隆项目
git clone -b beta https://github.com/flutter/flutter.git
2. 导出到Flutter保存路径
export PATH=
pwd/flutter/bin:$PATH
3. 使用镜像（国内可翻墙情况）。（如果可以直接连国外这里是可行的。不行跳至4）
cd ./flutter
flutter doctor
4. 使用镜像。由于在国内访问Flutter有时可能会受到限制，Flutter官方为中国开发者搭建了临时镜像，可以将如下环境变量加入到用户环境变量中：
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
flutter doctor
最后，好像是我本机上根据终端提示进行升级。
**更新出现错误
$ flutter doctor
MacBook-Pro-cql:flutter chenql$ flutter doctor

出现**[!]XX** 然后根据后面提示，运行命令。如上所示的
其他语句执行都正常；到这句：
$brew install --HEAD libimobiledevice
执行到这句时一直提示错误
$ brew install --HEAD libimobiledevice

搜索很多文章，最后有篇文章Flutter开发环境搭建-踩坑指南提示，一直运行直到初始化成功。我还是坚持要咬牙运行了不下20几次（估计）。
