Angular 未找到@ngrx/core@^6.1.0的匹配版本

我正在将angular 4升级到angular 6应用程序。我已更新了我的package.json，并收到以下错误：未找到与@ngrx/core@^6.1.0匹配的版本。不知道问题出在哪里。我发现很难找出我们缺少的依赖性。请在下面找到my Package.json的副本

Ngrx包，如其在

@ngrx/商店@ngrx/效果@ngrx/路由器商店@ngrx/商店开发工具 @ngrx/实体@ngrx/示意图

链接到那里的迁移指南：

希望这有帮助

不再需要它了：

@不再需要ngrx/核心，并且与@ngrx/存储冲突。去除 项目中的依赖项

也许，这是因为不再使用@ngrx/core包。2016年，它从未超过1.2版。
