我的vs代码出现了一个“获取包裹”按钮，我错误地按了它。

现在，即使我的包被固定（特别是一个）在某个版本上，它总是尝试使用最新版本运行项目，这给我带来了如下错误：

/C:/Users/j/AppData/Local/Pub/Cache/hosted/pub.dartlang.org/serverpod_serialization-0.9.20/lib/src/serialization.dart:21:11: Context: 'SerializableEntity.toJson' is defined here.

请注意，它引用了< code > server pod _ serialization-0 . 9 . 20

我所有的serverpod东西都固定在^0.9.8

我尝试过这样的东西:如何从flutter中移除或识别未使用的包以减少项目的规模？

清除pubspek. lock文件、.pub-cache文件夹、flutter净flutter pub get一切。我的项目中的任何文件都没有引用0.9.20，所有pubspec.yaml文件都将其固定：

dependencies:
  serverpod_client: ^0.9.8

那么，颤振从哪里得到0.9.20？或者更重要的是，我怎么才能把一切都弄清楚？

奇怪的是，如果我重新克隆它并运行＜code＞dart-pub-get＜/code＞，然后查看它创建的pubspok.lock

  serverpod_client:
    dependency: "direct main"
    description:
      name: serverpod_client
      url: "https://pub.dartlang.org"
    source: hosted
    version: "0.9.20"

尽管 Pubspec.yaml 清楚地将其固定在 0.9.8，但这告诉我问题不在于项目或存储库或缓存，而是在我的实际颤振安装中，但不知何故......颤动的缓存？

下面是该错误的扩展版本：
