Question

制作ng update并运行ng serve后出现此错误：

ERROR in node_modules/@agm/core/services/maps-api-loader/lazy-maps-api-loader.d.ts(1,10): error TS2305: Module '"/home/maroodb/WebstormProjects/user-dashboard-ng/node_modules/@angular/core/core"' has no exported member 'OpaqueToken'.

我认为这是由于从angular2升级到angular5引起的。但我没弄清楚如何解决这个问题。

更新这是我的package.json

如果您使用的是@ angular / flex-layout，则以下步骤可能有所帮助：

删除您的node-modules目录
删除项目package.json
运行npm i; npm i @ angular / flex-layout

如果你没有使用flex-layout，可以提供更多信息（你的package.json）。

升级角度模板后，我遇到了一个错误
