解决方案 #

方法1：配置环境变量指定自带JDK #

Android Studio Electric Eel自带JDK，只需手动配置JAVA_HOME指向它：

• 打开终端，执行以下命令设置环境变量：
  • 若使用Zsh：

    echo 'export JAVA_HOME="/Applications/Android Studio.app/Contents/jbr/Contents/Home"' >> ~/.zshrc
    source ~/.zshrc
    

  • 若使用Bash：

    echo 'export JAVA_HOME="/Applications/Android Studio.app/Contents/jbr/Contents/Home"' >> ~/.bash_profile
    source ~/.bash_profile
    

• 验证配置：

  java -version
  flutter doctor
  

  能正常显示Java版本且flutter doctor不再报Java相关错误即为成功。

方法2：在Android Studio中指定JDK路径 #

• 打开Android Studio，依次进入File > Project Structure > SDK Location
• 在JDK location栏中选择路径：/Applications/Android Studio.app/Contents/jbr/Contents/Home
• 点击Apply保存，重启Android Studio后重新运行flutter doctor。

方法3：重装Android Studio（备选） #

若前两种方法无效，卸载当前版本后重新下载安装Android Studio Electric Eel，安装时确保勾选JDK相关组件。
