如何修复 Nestjs 应用程序上的 CustomRepositoryCannotInheritRepositoryError？

Question

运行nestjs应用程序时遇到问题。

当前生态系统：
- Windows 10
-node版本：v12.10.0
-npm版本：6.10.3
-nestjs版本：6.14.2

重现步骤：

git clone https://github.com/gandra/nestjs-task-managament
cd nestjs-task-managament
npm i
npm run start

收到以下错误：

CustomRepositoryCannotInheritRepositoryError: Custom entity repository TaskRepository  cannot inherit Repository class without entity being set in the @EntityRepository decorator.

似乎以下两件事解决了问题。首先，我将TaskRepository注释从更改@EntityRepository()为@EntityRepository(Task)。修复后我遇到了错误EntityMetadataNotFound。然后我更改了TypeOrm entities文件中的 consrc/config/typeorm.config.ts并替换entities: [__dirname + '/../**/*.entity.ts'],为entities: [__dirname + '/../**/*.entity.{js,ts}'],.
