我已经修复了一些错误，但这些是关于模块的，我对这些错误一无所知。

Answer 1

我解决了这个问题，实际上我使用的是angular2-jwt（已弃用）和@auth0/angular-jwt。这引起了问题。所以我用@auth0/angular-jwt卸载了angular2-jwt更新代码，一切都开始正常工作了。

Answer 2

我使用 @auth0/angular-jwt 和 angular 解决了这个问题 6. 您首先需要完全卸载 angular2-jwt：

npm uninstall angular2-jwt --save

那么你可以运行:

npm install @auth0/angular-jwt

只有这两个命令行帮助了我。祝一切顺利。
