Question

我遵循了nestJs的教程，并有一个基本的工作应用程序。之后，我尝试了本教程将应用程序与webpack和hotreloading连接起来，现在出现以下错误：

import { Entity, Column, PrimaryGeneratedColumn } from 'typeorm';
SyntaxError: Unexpected token {
    at Module._compile (internal/modules/cjs/loader.js:703:23)

我尝试查看类似的错误，并且除了这里和那里的提示以外，找不到任何结论性内容，这些都是我的测试文件中未编译的内容-任何方向将不胜感激。

使用节点12，npm 6.9.0

将JSON打包如下：

Answer 1

这可能是tsconfig，您使用的是： "module": "commonjs"在compilerOptions中？在使用nodejs时，这是您必须使用的选项

Answer 2

我最终将此内容发布在NestJS存储库上，并收到了有兴趣的人的答复： https://github.com/nestjs/nest/issues/2389
