Flutter环境变量配置

Posted 2023-02-21 建古

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

报错二，1、配置java环境变量 参考(https://www.cnblogs.com/lude1994/p/13344681.html)
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.
      See https://flutter.dev/docs/get-started/install/macos#android-setup for
