编译我的角度项目时，出现以下错误。我删除了我的 node_modules 文件并重新安装它仍然无法正常工作。

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”。

我遇到了这个问题并找到了解决方案。在查看“对于 Angular v6+ 到 v9，使用 @auth0/angular-jwt v4”的文档后，我目前正在运行 Angular 6 并安装了 4.2 版。我得到了同样的错误：

失败：Microsoft.AspNetCore.SpaServices[0] node_modules/@auth0/angular-jwt/lib/jwtoptions.token.d.ts(2,50)：错误 TS2304：找不到名称“未知”。

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>;

“未知”是 typescript 3 中引入的一种新类型，Angular 6.0.9 依赖于 typescript ~2.7。此外，@auth0/angular-jwt 依赖项的 4.2 版本针对 Angular 7.1+，正如您从这个 npm 警告中看到的那样：

npm WARN @auth0/angular-jwt@4.2.0 需要 @angular/common@>=7.1.0 的对等点，但没有安装。您必须自己安装对等依赖项。

我认为这个包遇到了支持旧版本 Angular 的问题。我只是降级到版本@auth0/angular-jwt@3.0.1 并且不再有错误。
