Javascript 角度6-由于NGRX,生产构建失败
我想使用以下命令生成并测试生产构建:Javascript 角度6-由于NGRX,生产构建失败,javascript,angular,angular-material,angular-cli,ngrx,Javascript,Angular,Angular Material,Angular Cli,Ngrx,我想使用以下命令生成并测试生产构建: ng build --prod --configuration=production ng serve --prod --configuration=production 文件生成正确,但在浏览器中打开站点时,出现以下错误: 未捕获错误:StaticInjectorError[n->t]: 静态注入错误(平台:核心)[n->t]: NullInjectorError:没有t的提供程序 我的生产配置如下所示: "production": {
ng build --prod --configuration=production
ng serve --prod --configuration=production
文件生成正确,但在浏览器中打开站点时,出现以下错误:
未捕获错误:StaticInjectorError[n->t]:
静态注入错误(平台:核心)[n->t]:
NullInjectorError:没有t的提供程序
我的生产配置如下所示:
"production": {
"optimization": true,
"outputHashing": "all",
"sourceMap": true,
"extractCss": true,
"namedChunks": false,
"aot": true,
"extractLicenses": true,
"vendorChunk": true,
"buildOptimizer": true,
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}
]
},
我意识到问题在于在我的应用程序中使用ngrx。当我以某种方式删除连接到ngrx的所有内容时,应用程序将正常打开。
你知道我该修什么吗
下面我在我的应用程序中附上一些ngrx的例子
应用模块
export const metaReducers: MetaReducer<AppState>[] = !environment.production ? [storeFreeze] : [];
imports: [
BrowserModule,
BrowserAnimationsModule,
HttpClientModule,
StoreModule.forRoot(reducers, {metaReducers}),
EffectsModule.forRoot([AuthEffects]),
],
让我说,在AppModule中,我导入了SharedModule,它导出MaterialModule,它导出MatSnackBarModule。所以一切看起来都很好…这似乎是CLI中的一个错误,请查看相应的 作为解决方案,您可以尝试以下方法:
- 更新至@angular/cli和@angular devkit的最新版本(更新其他@angular软件包可能不会有什么坏处)
- 清除node_模块并重新安装
旁注:prod构建的行为有所不同,因为它在开发模式中使用AoT编译器(提前)而不是JIT编译器(及时)。由于AoT模式现在几乎和JIT一样快,我建议在开发过程中也使用它,所以如果出现问题,您会得到即时反馈。有关更多信息,请参见此说明。此错误的意思是,您的app.module.ts中没有提供任何服务。您可以发布整个app.module.ts吗this@SmokeyDawson你有没有关于如何识别丢失的服务的提示?你是否正在运行测试/应用程序中是否有.spec文件?如果是这样,您需要确保您正在组件测试床中导入MaterialModule.configureTestingModule({..})。是的,测试正在通过
