angular ngrx 组件中 constructor 内注入 Store 就会报错

Question

import {Store} from '@ngrx/store';
import {StateStoreModule} from '../../state-store/state-store.module';

constructor(private route: ActivatedRoute, private sheetService: sheetService, private store:Store<StateStoreModule>)

只要不引入 Store 一切正常

 "dependencies": {
    "@angular/animations": "~8.2.3",
    "@angular/common": "~8.2.3",
    "@angular/compiler": "~8.2.3",
    "@angular/core": "~8.2.3",
    "@angular/forms": "~8.2.3",
    "@angular/platform-browser": "~8.2.3",
    "@angular/platform-browser-dynamic": "~8.2.3",
    "@angular/router": "~8.2.3",
    "@ngrx/store": "^9.0.0",
    "@ngrx/store-devtools": "^9.0.0",
    "minireset.css": "0.0.5",
    "ng-zorro-antd": "^8.1.2",
    "rxjs": "~6.4.0",
    "tslib": "^1.10.0",
    "zone.js": "~0.9.1"
  },

这是package.json 配置文件

上述错误是提示你：没有找到Store的提供者，所以发生了NullInjectorError。解决的方法是在当前组件所有在的模块中的imports中，加入Store的提供者.

imports: [
   StoreModule  // 提供Store的模块
]
