ios - 当我运行 flutter run 时，Flutter iOS 构建失败

Question

我对 Flutter 有疑问。我无法在 iOS 模拟器上运行我的应用程序，也无法为 iOS 构建版本。运行应用程序时出现此错误:

# The following line prevents the package from being accidentally published to
# pub.dev using `pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43

# Both the version and the builder number may be overridden in flutter

# In Android, build-name is used as versionName while build-number used as versionCode.

我使用的是 flutter 1.22.5 版本。我该如何解决这个问题，我已经尝试了所有的解决方案，但到目前为止我的问题还没有解决。

Answer 1

1. 删除 Podfile.lock
2. 在 iOS 目录中运行 pod install
3. Flutter clean && flutter run

你应该可以开始了。
