我将所有与数据库相关的操作移动到一个独立的模块中:
@Module({
imports: [
TypeOrmModule.forFeature([
PostRepository,
UserRepository,
CommentRepository,
]),
],
exports: [PostRepository, UserRepository, CommentRepository],
providers: [PostsDataInitializer],
})
export class DatabaseModule {}

但是在其他模块中,当我导入DatabaseModule并尝试注入PostRepository服务类时,出现以下错误。
Nest cannot export a provider/module that is not a part of the currently processed module (DatabaseModule).
Please verify whether the exported PostRepository is available in this particular context.

在阅读了我的一些 Angular 代码后,我自己解决了这个问题,只需TypeOrmModule将DatabaseModule.
@Module({
imports: [
TypeOrmModule.forFeature([
PostRepository,
UserRepository,
CommentRepository,
]),
],
exports: [TypeOrmModule],
providers: [PostsDataInitializer],
})
export class DatabaseModule {}
