构建 flutter macos 应用程序时我应该做什么来更改 MACOSX_DEPLOYMENT_TARGET

Question

我正在使用以下命令v3.0.4在 macOS( ) 中构建 flutter( ) macos 应用程序：v12.4 M1 chip

\n

~/fvm/versions/3.0.4/bin/flutter build macos --release\n

\n

显示这样的错误：

\n

    \xe2\x9e\x9c  macos git:(main) \xe2\x9c\x97 ~/fvm/versions/3.0.4/bin/flutter build macos --release --no-tree-shake-icons\nChanging current working directory to: /Users/xiaoqiangjiang/source/reddwarf/frontend/tik\n\n Building with sound null safety \n\nRunning pod install...                                             668ms\n--- xcodebuild: WARNING: Using the first of multiple matching destinations:\n{ platform:macOS, arch:arm64, id:00006000-001248980AE2801E }\n{ platform:macOS, arch:x86_64, id:00006000-001248980AE2801E }\n/Users/xiaoqiangjiang/source/reddwarf/frontend/tik/macos/Pods/Pods.xcodeproj: warning: The macOS deployment target \'MACOSX_DEPLOYMENT_TARGET\' is set to 10.6, but the range of supported deployment target versions is 10.9 to 12.3.99.

我已经将 Pods 和 Runner 部署目标更改为 10.11。我应该怎么做才能更改MACOSX_DEPLOYMENT_TARGET 版本？这是 macOS 的 podfile：

\n

platform :osx, \'10.11\'\n\n# CocoaPods analytics sends network stats synchronously affecting flutter build latency.\nENV[\'COCOAPODS_DISABLE_STATS\'] = \'true\'\n\nproject \'Runner\', {\n  \'Debug\' => :debug,\n  \'Profile\' => :release,\n  \'Release\' => :release,\n}\n\ndef flutter_root\n  generated_xcode_build_settings_path = File.expand_path(File.join(\'..\', \'Flutter\', \'ephemeral\', \'Flutter-Generated.xcconfig\'), __FILE__)\n  unless File.exist?(generated_xcode_build_settings_path)\n    raise "#{generated_xcode_build_settings_path} must exist. If you\'re running pod install manually, make sure \\"flutter pub get\\" is executed first"\n  end\n\n  File.foreach(generated_xcode_build_settings_path) do |line|\n    matches = line.match(/FLUTTER_ROOT\\=(.*)/)\n    return matches[1].strip if matches\n  end\n  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Flutter-Generated.xcconfig, then run \\"flutter pub get\\""\nend\n\nrequire File.expand_path(File.join(\'packages\', \'flutter_tools\', \'bin\', \'podhelper\'), flutter_root)\n\nflutter_macos_podfile_setup\n\ntarget \'Runner\' do\n  use_frameworks!\n  use_modular_headers!\n\n  flutter_install_all_macos_pods File.dirname(File.realpath(__FILE__))\nend\n\npost_install do |installer|\n  installer.pods_project.targets.each do |target|\n    flutter_additional_macos_build_settings(target)\n  end\nend\n

\n

这是 Pods macOS 部署配置：

我已经尝试清理构建并重建 macos 应用程序，但仍然无法按预期工作。

Answer 1

进入我的 macos/Podfile 并替换看起来像这样的 post_install 方法 \xe2\x80\xa6

\n

post_install do |installer|\n  installer.pods_project.targets.each do |target|\n    flutter_additional_macos_build_settings(target)\n  end\nend\n

\n

看起来像这样。

\n

post_install do |installer|\n  installer.pods_project.targets.each do |target|\n    flutter_additional_macos_build_settings(target)\n    target.build_configurations.each do |config|\n      config.build_settings[\'MACOSX_DEPLOYMENT_TARGET\'] = \'10.15\'\n    end\n  end\nend\n

Answer 2

在 Xcode 中打开macos文件夹，然后在项目导航器中选择Pods 。选择框架目标并选择常规选项卡。

在 Pod 中更改此部署目标并保存将解决该问题的更改

Answer 3

经过几个小时寻找解决方案，找到了。

需要在两个地方进行更改，但更改为同一个文件。该文件是 macos/Runner.xcworkspace

在 Finder 中显示它，并使用 XCode 打开。

文件中的第一个更改：运行程序 > 常规 > 最小部署。设置为列表中的最小值或所需值（在我的例子中为 10.13）

文件中的第二个更改：Flutter Assemble > Build Settings > macOS Deployment Target。设置为与之前相同（在我的例子中为 10.13）

要切换到 Flutter Assemble，请使用 Runner 下面的子菜单。这是我的困惑。这 2 个更改需要在同一个文件中进行，并且只需在 Runner 下的上方菜单中选择 Runner 或 Flutter Assemble。也请参阅以下视频，其中包含详细信息

希望这能有所帮助。
