Mac 上的 Flutter 项目（从 Windows 复制）

【中文标题】Mac 上的 Flutter 项目（从 Windows 复制）

【英文标题】：Flutter project on Mac (copied from Windows)

【发布时间】：2020-04-17 09:57:27

【问题描述】：

我从朋友那里收到了 Flutter 项目，用于在 Mac 上构建 ios 版本的应用程序（Catalina 和 Xcode 11.3）。 Flutter 项目是在 Windows 中制作并为 android 制作的。现在我应该在同一项目的 Mac 上制作 iOS 版本。

我和我的朋友对 Flutter 很陌生。我几乎没有 Xcode 经验（构建导出的 Unity 项目）。

我想了解 Flutter 需要做什么。我可以创建测试项目并在模拟器中运行它。但是这个项目行不通。

flutter doctor -v 的输出似乎没问题：

我尝试清理构建文件夹并重新创建项目：

In order to run your application, type:

  $ cd example
  $ flutter run

Your application code is in example/lib/main.dart.

Your plugin code is in ./lib/TestApp.dart.

Host platform code is in the "android" and "ios" directories under ..
To edit platform code in an IDE see
https://flutter.dev/developing-packages/#edit-plugin-package.

颤动运行 lib/TestApp.dart

Launching lib/TestApp.dart on iPhone 11 Pro Max in debug mode...
Expected ios/Runner.xcodeproj but this file is missing.
No application found for TargetPlatform.ios.
Is your project missing an ios/Runner/Info.plist?
Consider running "flutter create ." to create one.

flutter build ios lib/alylatu.dart

Expected ios/Runner.xcodeproj but this file is missing.
Application not configured for iOS

我什至尝试将文件从测试项目复制到 TestApp 文件夹，但没有成功。

我应该将 TestApp 项目配置为 iOS 项目吗？ 我没有安装 Brew。我应该安装它和其他东西吗？

有什么想法吗？

【问题讨论】：

尝试在 projet 文件夹中运行flutter create .。

项目是应用程序还是插件？ flutter create 输出显示它为插件而不是应用程序创建文件，但您正试图将其作为应用程序运行。

一些文件丢失或者被删除运行flutter create ios

【参考方案1】：

我收到了类似以下的错误：

      Expected ios/Runner.xcodeproj/project.pbxproj but this file is missing.
      No application found for TargetPlatform.ios.
      Is your project missing an ios/Runner/Info.plist?
      Consider running "flutter create ." to create one.

问题是我从 Git 存储库中克隆了项目。 project.pbxproj 文件位于 .gitignore 中。所以，我创建了一个新的 Flutter 项目并将其他文件复制到其中。

【参考方案2】：

这对我有用：

1) 创建一个新的颤振项目。 2）运行项目并确保其顺利运行。 3) 验证项目运行后，转到您的新项目：

项目目录 iOS 文件夹

复制以下内容：

Runner.xcodeproj 和 Runner.xcworkspace

将这些粘贴到您的旧项目（Project/ios）中，然后保存并运行。这对我有用，希望它会有所帮助。
