【Flutter小技巧02】Flutter环境变量配置

配置简单，每次配置好了就丢一边，下次在配置又要各种找，好记性不如烂笔头！

1、打开配置文件 方式一：vim ~/.bash_profile vim编辑 退出vim: 编辑状态下，按esc, 输入 :wq 保存退出 方式二：open ~/.bash_profile 打开配置文件 可视化编辑 2、编辑配置文件

export PATH=/Users/yangjian/Documents/Flutter/flutter/bin:$PATH
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=$PATH:/Users/yangjian/Library/Android/sdk/platform-tools
export PATH=$PATH:/Users/yangjian/Library/Android/sdk/tools

其中/yangjian/Documents/Flutter/flutter/bin的是flutter sdk解压的目录

3、刷新

source ~/.bash_profile

4、检测

flutter doctor 

注：如果flutter命令运行提示 zsh: command not found: flutter，就是没有配置全局的环境变量

5、常见报错解决方案

2、flutter doctor --android-licenses 每个协议都y下

    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
