接上节这里先说下系统环境 MacOS14 Sonoma 芯片 Apple M3 执行命令flutter doctor 提示如下
[!] Flutter (Channel stable, 3.13.9, on macOS 14.1.1 23B2082 darwin-arm64, locale en-CN)✗ Downloaded executables cannot execute on host.See https://github.com/flutter/flutter/issues/6207 for more information.Flutter requires the Rosetta translation environment on ARM Macs. Try running:sudo softwareupdate --install-rosetta --agree-to-license
[!] Android toolchain - develop for Android devices (Android SDK version 34.0.0)✗ cmdline-tools component is missingRun path/to/sdkmanager --install cmdline-tools;latestSee https://developer.android.com/studio/command-line for more details.✗ 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 more details.
[!] Xcode - develop for iOS and macOS (Xcode 15.0.1)✗ CocoaPods not installed.CocoaPods is used to retrieve the iOS and macOS platform sides plugin code that responds to yourplugin usage on the Dart side.Without CocoaPods, plugins will not work on iOS or macOS.For more info, see https://flutter.dev/platform-pluginsTo install see https://guides.cocoapods.org/using/getting-started.html#installation forinstructions.这里需要说明的是 此时还与开发配置无关仅仅是检查开发工具是否符合要求下面就提示做详细说明
1、Downloaded executables cannot execute on host.
上节我们说了 用 usrname -a 查看 芯片型号以便下载对应的 flutter SDK此处提示 SDK要在 ARM 架构芯片上运行 需要执行命令 sudo softwareupdate --install-rosetta --agree-to-license按照提示输入命令即可所以输入
sudo softwareupdate --install-rosetta --agree-to-license
解决第一个问题接着提示
2、✗ cmdline-tools component is missing 和 ✗ Android license status unknown. 对于第一个可能有些莫名其妙提示是 Run path/to/sdkmanager --install cmdline-tools;latest 难道是执行命令
非也即便你命令行到 Android SDK目录 去执行那个提示命令也会提示错误正确方式打开 上节我们安装好的 Android Studio下载安装 cmdline-tools; 具体先看图 打开 Android Studio 找到“设置”选项按图所示 找到 Android SDK 选择然后在右边的选项卡中选中 Android SDK Command-line Tools (latest) ⚠️勾选第三项 当然 Flutter开发 移动端 大部分时间也会用到 NDK你也可以一次安装好不过这不是必须根据项目需要选择安装这是一个漫长的下载安装过程取决于你的网络状况 Command-line Tools 下载安装完成后执行命令
#Command-line Tools 安装成功后 执行命令
flutter doctor --android-licenses
一系列的同意条款按提示操作即可✅完成以上操作后
再次执行 flutter doctor 结果如下 MacOS 下 flutter 开发环境 Android安卓部分基本配置完毕进入项目命令行 flutter build apk 试试
josonMacBook ios % flutter build apk

Running Gradle task assembleRelease... 187.5s
Gradle task assembleRelease failed with exit code 1 打开Android Studio 错误提示一样 由于喜欢用VsCode 作为编辑器然后命令行方式调试和编译 所以很少直接用的 Android Studio问题很明显了是网络问题同时打开 Android Studio 一样提示无法下载文件 百度 关键词 Maven Gradle解决吧具体可以参考 这篇文章 下一节MacOS 14 系统 XCode15、 Flutter 开发 IOS
