我使用Hive Packages，我在我的项目中实现模块化。首先我network使用运行命令创建具有名称的包flutter create --template=package network，我引用了这个。

这个包包括我的项目模型。之后我创建模型用户，然后运行命令构建模型flutter packages pub run build_runner build --delete-conflicting-outputs：

import 'package:hive/hive.dart';

part 'user_model_hive.g.dart';

@HiveType()
class UserModelHive extends HiveObject {
  @HiveField(0) 
  DateTime id;
  @HiveField(1)
  String giverName;
  @HiveField(2)
  String pinCodeNumber;

  UserModelHive({this.id, this.giverName, this.pinCodeNumber});
}

但我得到这样的错误

Could not find package "build_runner". Did you forget to add a dependency? pub finished with exit code 65

我确定已经包含build_runner在我的包裹network中。

我已经在使用此命令，但没有任何反应： flutter packages get&flutter pub get

如果需要，这是我的结构文件夹。 我的结构文件夹

我也遇到了同样的错误。我已经通过在 pubspec.yaml 文件中的 dev_depndencies 中添加 build_runner 来解决它，例如 -

dev_dependencies：

build_runner：^1.3.1

mobx_codegen: ^0.3.9

我遇到过这个问题

我更改了我的模型类 @HiveType() 注释

@HiveType(0)

就像那样。问题解决了。

正如评论中共享的 GitHub 问题中所述，该问题是由从不同目录运行应用程序引起的。在这种情况下，该应用程序在发布的问题中以 root 身份运行。通过从 运行应用程序已解决该问题/network。
