编译我的 Angular 项目时，出现以下错误。我删除了我的 node_modules 文件并重新安装它仍然没有用。
node_modules/@auth0/angular-jwt/lib/jwtoptions.token.d.ts(2,50) 中的错误:错误 TS2304:找不到名称“未知”。

最佳答案
我遇到了这个问题并找到了解决方案。查看 documentation 后，我目前正在运行 Angular 6 并安装了 4.2 版上面写着“对于 Angular v6+ 到 v9，使用 @auth0/angular-jwt v4”。我得到了同样的错误:
fail: Microsoft.AspNetCore.SpaServices[0] node_modules/@auth0/angular-jwt/lib/jwtoptions.token.d.ts(2,50): error TS2304: Cannot find name 'unknown'.
我在 node_modules 中打开了 jwtoptions.token.d.ts 文件，它是一个简单的两行文件:
import { InjectionToken } from '@angular/core';
export declare const JWT_OPTIONS: InjectionToken<unknown>;
'unknown' 是 typescript 3 中引入的新类型，Angular 6.0.9 依赖于 typescript ~2.7。此外，@auth0/angular-jwt 依赖项的 4.2 版本以 Angular 7.1+ 为目标，您可以从这个 npm 警告中看到:
npm WARN @auth0/angular-jwt@4.2.0 requires a peer of @angular/common@>=7.1.0 but none is installed. You must install peer dependencies yourself.
我认为这个包在支持旧版 Angular 时遇到了问题。我简单的降级到了@auth0/angular-jwt@3.0.1这个版本就没有报错了。
