Cannot find module "@auth0/angular-jwt/"

Question

I'm currently developing a Web Application using ADFS authentication.

I have the following runtime error:

"Cannot find module @auth0/angular-jwt".

I'm using Angular 5.2.10. I've tried to reinstalled my dependencies, however I still have errors:

I've errors in index.d.ts:

Cannot find name 'Provider'and 'ModuleWithProviders'

And in jwt.interceptor.d.ts:

Cannot find modules "@angular/common/http" and "rxjs/internal/Observable"

And in jwtoptions.token.d.ts:

Cannot find module "@angular/core"

I haven't modified any of those files.

Is this an angular version problem? Am I using wrong versions of those libraries?

Thanks for your help!

Answer 1

1. Delete your node_modules folder
2. Run npm i

Try running it again

Answer 2

Answering for your first query i.e Cannot find module @auth0/angular-jwt"

Make sure inside node_modules folder you have specified path :- @auth0/angular-jwt/src/

If yes then use

import { JwtHelperService } from '@auth0/angular-jwt/src/jwthelper.service';

if no then first run installation with npm or yarn

npm install @auth0/angular-jwt
 
# installation with yarn 
yarn add @auth0/angular-jwt
