NestJS 记录器无法在 Windows 上打印

Question

我正在使用他们的文档here中的NestJS starter。

• NestJS 7.6.15.
• 节点版本 12.20.1
• Windows 10 专业版（操作系统内部版本 19042.867）

我没有更改 main.ts 中的任何内容来更改记录器功能。

ma​​in.ts:

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(3000);
}
bootstrap();

我的记录器根本没有打印任何东西。示例：

import { Injectable, Logger } from '@nestjs/common';
import { Cron, CronExpression } from '@nestjs/schedule';

@Injectable()
export class ScheduledTask {
  private readonly logger = new Logger(ScheduledTask.name);

  @Cron(CronExpression.EVERY_5_SECONDS)
  handleCron() {
    this.logger.log('This does not print.');
  }
}

有什么想法吗？

看起来 NestJS 不会自动重建我的 dist 文件夹。一旦我手动删除它，它就会强制重建并开始显示日志。好像我每次更改代码时都需要这样做。
