我的 Nest 应用程序遇到了最奇怪的问题（生活在 Nx 中，无论它的价值如何）。我生成了一个新资源：

nx g resource --project testing
✔ Which generator would you like to use? · @nx/nest:resource
✔ What name would you like to use for this resource (plural, e.g., `users`)? · items
✔ What transport layer do you use? · graphql-code-first
✔ Would you like to generate CRUD entry points? (Y/n) · false

它被添加到Imports主 app.module 中：

@Module({
  imports: [
    GraphQLModule.forRoot<ApolloDriverConfig>({
      driver: ApolloDriver,
      playground: false,
      plugins: [ApolloServerPluginLandingPageLocalDefault()],
      autoSchemaFile: "schema.gql",
    }),
    ItemsModule,
  ],
})
export class AppModule {}

然后，我添加了简单的解析器以使 GraphQL 满意：

// ./items/items.resolver.ts
import { Int, Query, Resolver } from "@nestjs/graphql";

import type { ItemsService } from "./items.service";

@Resolver()
export class ItemsResolver {
  constructor(private readonly service: ItemsService) {}

  @Query(() => [Int])
  getAll() {
    return [1, 2, 3];
  }
}

所以我的 items.module 看起来像这样：


import { ItemsResolver } from "./items.resolver";
import { ItemsService } from "./items.service";

@Module({
  providers: [ItemsResolver, ItemsService],
})
export class ItemsModule {}

这对我来说非常有效。但尽管如此，我仍然得到 Error: Nest can't resolve dependencies of the ItemsResolver (?). Please make sure that the argument Object at index [0] is available in the ItemsModule context.

如果我从班级中删除该服务ItemsResolver，一切都会正常。
