TypeError: Class constructor MixinStrategy cannot be invoked without 'new'

TypeError: Class constructor MixinStrategy cannot be invoked without 'new'

我正在关注此处 https://docs.nestjs.com/techniques/authentication 中的 jwt 示例。我复制并粘贴了示例。在 npm 安装必要的位和 bops 之后,我得到了这个错误,这在我刚刚复制的示例中没有发生。我不知道这是什么意思!有人有什么想法吗?

TypeError: Class constructor MixinStrategy cannot be invoked without 'new'

   8 | export class JwtStrategy extends PassportStrategy(Strategy) {
   9 |   constructor(private readonly authService: AuthService) {
> 10 |     super({
  11 |       jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
  12 |       secretOrKey: 'secretKey',
  13 |     });

  at new JwtStrategy (data/auth/strategies/jwt.strategy.ts:10:5)
  at resolveConstructorParams (../node_modules/@nestjs/core/injector/injector.js:64:84)
  at Injector.resolveConstructorParams (../node_modules/@nestjs/core/injector/injector.js:86:30)

project 缺少 @types/passport-jwt 类型,因此应额外安装它们:

npm i -D @types/passport-jwt

这导致

src\auth\jwt.strategy.ts (10,6): Call target does not contain any signatures. (2346)

错误,因为 @nestjs/passport 没有正确输入; PassportStrategy return type is any.

为了解决这个问题,

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
...

应改为:

import { ExtractJwt, Strategy } from 'passport-jwt';
import { AbstractStrategy, PassportStrategy } from '@nestjs/passport';
...
const PassportJwtStrategy: new(...args) => AbstractStrategy & Strategy = PassportStrategy(Strategy);

@Injectable()
export class JwtStrategy extends PassportJwtStrategy {
...

在我的案例中,问题出在 tsconfig.ts 文件中,我正在使用 nest.js 并且在 cli 命令 typeorm init 之后它覆盖了 tsconfig,因此 npm run start:dev 抛出异常:TypeError: Class 没有 'new'

就无法调用构造函数 MixinStrategy

注意:package.json 也被旧版本 typescipt, @ts/node, ts-node

覆盖
