flutter pubspec.yaml退出代码65

Question

我的Flutter pubspec.yaml没有收到这些包。此错误显示：

Error on line 30, column 22 of pubspec.yaml: Invalid version constraint: Expected version number after "^" in "^^4.2.1", got "^4.2.1".

   ╷

30 │   animated_text_kit: ^^4.2.1

   │                      ^^^^^^^

   ╵
pub get failed (65;    ╵)
exit code 65

这是我的依赖项：

dependencies:
  flutter:
    sdk: flutter


  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  animated_text_kit: ^4.2.1
  cupertino_icons: ^1.0.3
  audioplayers: ^0.16.1

dev_dependencies:
  flutter_test:
    sdk: flutter

我检查了缩进，版本等等。

我该怎么办？

Answer 1

pubspec.yaml上的退出代码65表示该文件的格式不正确。您需要再次检查文件，问题出在哪里，或者共享完整的yaml文件，以便我可以检查。或者，如果您对格式很有信心，可以尝试在终端中使用flutter clean，然后使用flutter pub get。

尝试下面的代码，然后运行flutter pub get refer documentation here

dependencies:
  flutter:
    sdk: flutter
  audioplayers: ^0.16.1
  animated_text_kit: ^4.2.1

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  
  cupertino_icons: ^1.0.3
