NestJS authGuard 有效

Question

我正在实现@nestjs/passport ('jwt') 并使用（与说明完全一样） @UseGuards(AuthGuard())装饰器，但出现以下异常：

common_1.Optional 不是函数

有谁知道可能是什么问题？

依赖项：

"@nestjs/common": "^5.0.0",

 "@nestjs/core": "^5.0.0", "@nestjs/cqrs": "^5.1.1", "@nestjs/jwt": "^0.2.0", "@nestjs/mongoose": "^5.1.0", "@nestjs/passport": "^5.1.0", "@nestjs/swagger": "^2.4.4", "@nestjs/typeorm": "^5.2.2", "automapper-ts": "^1.9.0", "config": "^2.0.1", "fastify-formbody": "^2.0.0", "lodash": "^4.17.10", "mongodb": "^3.1.6", "mongoose": "^5.2.9", "mysql": "^2.16.0", "nestjs-rmq": "^0.1.3", "nestjs-typegoose": "^5.0.1", "passport": "^0.4.0", "passport-jwt": "^4.0.0", "reflect-metadata": "^0.1.12", "rxjs": "^6.0.0", "typegoose": "^5.4.0", "typeorm": "^0.2.7", "typescript": "^2.6.2",

Answer 1

依赖项已过时。 尝试运行npm update 。

Answer 2

也许我不太理解这个问题，但是要使用守卫，您可以提供守卫实例或提供类并让嵌套创建实例，守卫是**不是函数*

@UseGuards(AuthGuard())应该是： @UseGuards(new AuthGuard())或@UseGuards(AuthGuard)

Answer 3

看起来您使用旧的依赖项。

安装 npm g npm-check

运行 npm-check -u

https://www.npmjs.com/package/npm-check

Answer 4

依赖问题

尝试这个 ：

$ sudo npm install -g npm-check

$ npm-check -u
