NestJS无法解析AuthServices的依赖项 [英] NestJS can't resolve dependencies of the AuthServices

问题描述

在第一个JWT_MODULE_OPTION问题之后，返回我以为我已经解决了这个老问题.原来，当我解决"旧问题时，请使用JWT创建新问题.

After first problem with JWT_MODULE_OPTION, back to old problem who I thought I was fixed. It turned out that when I "fix" old problem create the new with JWT.

所以再次无法编译:

嵌套不能解析AuthService的依赖项(?，RoleRepository，JwtService).请确保在AppModule上下文中索引[0]处的参数可用. + 25ms

这真的很奇怪，因为这种方式可以在我的另一个项目上工作，并且无法理解我哪里写错了.这是 auth.service.ts :

It's really strange, because this way work on another my project and can't understand where I'm wrong. Here is the auth.service.ts:

@Injectable()
export class AuthService {
    constructor(
        @InjectRepository(User) private readonly userRepo: Repository<User>,
        @InjectRepository(Role) private readonly rolesRepo: Repository<Role>,
        private readonly jwtService: JwtService,
    ) { }

它获得了角色和jwtService，但是问题出在User上，路径正确.这是 app.module.ts :

It get role and jwtService but the problem is with User, the path is correct. Here is app.module.ts:

@Module({
  imports: [
    TypeOrmModule.forRootAsync({
      imports: [ConfigModule, AuthModule],
      inject: [ConfigService],
      useFactory: async (configService: ConfigService) => ({
        type: configService.dbType as any,
        host: configService.dbHost,
        port: configService.dbPort,
        username: configService.dbUsername,
        password: configService.dbPassword,
        database: configService.dbName,
        entities: ['./src/data/entities/*.ts'],
      }),
    }),
  ],
  controllers: [AppController, AuthController],
  providers: [AuthService],
})
export class AppModule { }

对于控制器&具有相同的编译错误；提供者和不明白怎么了...

Have the same compile error for controllers & providers & can't understand what is wrong...

推荐答案

您可能缺少TypeOrmModule.forFeature([User])导入.通常，所有实体都将导入到专用功能模块中.如果只有一个模块(即AppModule)，则除了forRoot导入之外，还需要在其中放置forFeature导入.

You might be missing the TypeOrmModule.forFeature([User]) import. Typically, all entities are imported in dedicated feature modules. If you only have one module (i.e. AppModule) you need to put the forFeature import there in addition to the forRoot import.

@Module({
  imports: [
    TypeOrmModule.forRootAsync({...}),
    TypeOrmModule.forFeature([User, Role]),
  ],
