我有 Mac 并使用 Android Studio 和 Xcode，當我嘗試運行我的 Flutter 應用程式或嘗試執行 Build -> Build iOS 時收到以下錯誤訊息 我嘗試了我在網路上找到的大多數解決方案，例如：pod install or remove檔案，，和其他解決方案，但沒有幫助我，如何解決？謝謝

Manage your Flutter app development.
Common commands:
flutter create <output directory>
Create a new Flutter project in the specified directory.
flutter run [options]
Run your Flutter application on an attached device or in an emulator.
Usage: flutter <command> [arguments]
Global options:
-h, --help Print this usage information.
-v, --verbose Noisy logging, including all shell commands executed.
If used with "--help", shows hidden options. If used with "flutter doctor", shows additional diagnostic information. (Use "-vv" to force
verbose logging in those cases.)
--prefixed-errors Causes lines sent to stderr to be prefixed with "ERROR:".
--quiet Reduce the amount of output from some commands.
--[no-]wrap Toggles output word wrapping, regardless of whether or not the output is a terminal.
(defaults to on)
--wrap-column Sets the output wrap column. If not set, uses the width of the terminal. No wrapping occurs if not writing to a terminal. Use "--no-wrap" to
turn off wrapping when connected to a terminal.
-d, --device-id Target device id or name (prefixes allowed).
--version Reports the version of this tool.
--machine When used with the "--version" flag, outputs the information using JSON.
--[no-]color Whether to use terminal colors (requires support for ANSI escape sequences).
(defaults to on)
--[no-]version-check Allow Flutter to check for updates when this command runs.
(defaults to on)
--suppress-analytics Suppress analytics reporting when this command runs.
--packages Path to your "package_config.json" file.
Local build selection options (not normally required):
--local-engine-src-path Path to your engine src directory, if you are building Flutter locally.
Defaults to $FLUTTER_ENGINE if set, otherwise defaults to the path given in your pubspec.yaml dependency_overrides for sky_engine, if any.
--local-engine Name of a build output within the engine out directory, if you are building Flutter locally.
Use this to select a specific version of the engine if you have built multiple engine targets.
This path is relative to "--local-engine-src-path" or "--local-engine-src-out" (q.v.).
Options for testing the "flutter" tool itself:
--show-test-device List the special "flutter-tester" device in device listings. This headless device is used to test Flutter tooling.
--show-web-server-device List the special "web-server" device in device listings.
Available commands:
Flutter SDK
bash-completion Output command line shell completion setup scripts.
channel List or switch Flutter channels.
config Configure Flutter settings.
doctor Show information about the installed tooling.
downgrade Downgrade Flutter to the last active version for the current channel.
precache Populate the Flutter tool's cache of binary artifacts.
upgrade Upgrade your copy of Flutter.
Project
analyze Analyze the project's Dart code.
assemble Assemble and build Flutter resources.
build Build an executable app or install bundle.
clean Delete the build/ and .dart_tool/ directories.
create Create a new Flutter project.
drive Run integration tests for the project on an attached device or emulator.

以下是您可以遵循的一些步驟：-
cd .. 你的顫振專案運行flutter clean
運行你的專案 iOS 目錄Xcode
轉到首選項-> 位置并清除派生資料
然后在終端中運行 cd.. your_project_path/iOS
然后運行pod install
然后使用 Xcode 在模擬器中運行您的代碼
也許它可以解決你的問題
uj5u.com熱心網友回復：
通過運行命令將專案依賴項升級到最新版本
flutter pub upgrade
轉到專案運行的 iOS 檔案夾
pod init
和
pod install
我希望這個解決方案可以解決您的問題。
如果這個答案對你有幫助，請投票。
uj5u.com熱心網友回復：
前一小時我有同樣的錯誤
在我的情況下，解決方案是繼續這個步驟：
- Backup Runner 檔案夾
- 洗掉ios檔案夾
- 轉到終端并
flutter create .在flutter專案檔案夾中執行 - 將 Runner 檔案夾粘貼回 ios 檔案夾
pod deintegrate在 ios 檔案夾中pod install也在ios檔案夾中flutter clean在顫振專案檔案夾中flutter pub getflutter run
請注意，如果您使用 firebase，您需要重新插入 GoogleService-Info.plist 檔案
