Question

我是NativeScript的新手，我想使用状态管理NGXS并实现到我的应用程序。我已将NGXS与NPM一起安装：@ngxs/store @ngxs/logger-plugin和@ngxs/devtools-plugin。

所以我将那些NGXS模块添加到了我的app.module。

import { NgModule, NO_ERRORS_SCHEMA } from "@angular/core";
import { NativeScriptModule } from "nativescript-angular/nativescript.module";
import { NativeScriptUISideDrawerModule } from "nativescript-ui-sidedrawer/angular";

import { NgxsModule } from '@ngxs/store';
import { NgxsLoggerPluginModule } from '@ngxs/logger-plugin';
import { NgxsReduxDevtoolsPluginModule } from '@ngxs/devtools-plugin';

import { AppRoutingModule } from "./app-routing.module";
import { AppComponent } from "./app.component";
import { PetState } from './_ngxs/pet/pet.state';

@NgModule({
  bootstrap: [
    AppComponent
  ],
  imports: [
    AppRoutingModule,
    NativeScriptModule,
    NativeScriptUISideDrawerModule,
    NgxsModule.forRoot([
        //if i uncomment PetState, in console log show me error, Failed to find module: "./pet.actions"
        // PetState
    ]),
    //if i uncomment `NgxsLoggerPluginModule.forRoot()`, in console log show me error, Failed to find module: "@ngxs/logger-plugin
    // NgxsLoggerPluginModule.forRoot(),
    //if i uncomment `NgxsReduxDevtoolsPluginModule.forRoot()`, in console log show me error, Failed to find module: "@ngxs/devstool-plugin
    // NgxsReduxDevtoolsPluginModule.forRoot() 
  ],
  declarations: [
    AppComponent
  ],
  schemas: [
    NO_ERRORS_SCHEMA
  ]
})
export class AppModule { }

添加ngxs模块后，我遇到了2个问题。

NgxsModule.forRoot

如果我取消注释PetState，则会在控制台日志中引发我错误，找不到模块：“ ./ pet.actions”。请参阅
如果我取消注释NgxsLoggerPluginModule.forRoot() / NgxsReduxDevtoolsPluginModule.forRoot()，则会在控制台日志中出现错误，并说failed to find module @ngxs/logger-plugin / @ngxs/devstool-plugin

下面是pet.state.ts码

import { State, Action, Selector, StateContext } from '@ngxs/store';
import { Pet } from './pet.model';
import { AddPet, RemovePet } from './pet.actions';

export class PetStateModel {
  pets: Pet[];
}

@State<PetStateModel>({
  name: 'Pet',
  defaults: {
    pets: []
  }
})

export class PetState {

  @Selector()
  static getPet(state: PetStateModel) {
    return state.pets;
  }

  @Action(AddPet)
  addPet({getState, patchState}: StateContext<PetStateModel>, { payload }: AddPet) {
    const state = getState();
    patchState({
        pets: [...state.pets, payload]
    })
  }

  @Action(RemovePet)
  removePet({getState, patchState}: StateContext<PetStateModel>, { payload }: RemovePet) {
    const state = getState();
    patchState({
        pets: state.pets.filter(a => a.name !== payload )
    })
  }
}

我真的需要有人可以帮我解决问题，谢谢，

好的，我找到了解决方案。几个小时后，我找到了此解决方案here以及我的解决方案

只需删除node_modules，hook和platform文件夹，然后删除npm i并为iOS和android添加platform。

还有另外1件事，我不确定为什么，我为@ngxs/logger-plugin和@ngxs/devtools-plugin进行了卸载，然后重新安装到非dev依赖的依赖中。

无论如何，现在它对我有用。

将app.module中的NativeScript导入NGXS模块在日志控制台中引发错误
