I am working with a project using Material Component in Angular 5. I did update my Visual code but I don't know what happened. I am facing an issue "Type 'ElementRef' is not generic." I have been stuck on this issue since morning.
此行中的错误
Error in this line
_inputElement: ElementRef<HTMLInputElement>;

推荐答案
我认为问题可能出在如果您使用的是Angular Material 6，但仍使用Angular 5，那么您将收到此错误.当我安装Angular 5.x.x版本时，安装Angular Material 6 RC 12时会寻找Angular 6 Beta 0的对等依赖项.
I think the problem could be if your you are using Angular Material 6 but still Angular 5 then you will get this error. When installing Angular Material 6 RC 12 it's looking for a peer dependency for Angular 6 Beta 0 while I had a Angular 5.x.x version.
解决方案:
- 将Angular Material降级到Angular的相同主要版本(例如v5.x.x)
- 将Angular和Material升级到最新的RC版本，并在边缘享受生活. (例如v6.x.x RCx)
PS:他们在ng-conf 2018上宣布，从版本6开始，Angular，Angular Material和Angular CLI的所有版本号将保持同步，因此了解功能和兼容性将变得更加容易，希望您会成功.不会再有这个问题了.
PS: They announced at ng-conf 2018 that from version 6 onwards all the version numbers for Angular, Angular Material and Angular CLI will stay in sync so knowing what goes with what and compatibility will be much easier and hopefully you won't have this problem again.
