Although I have already looked for a solution to this problemhere, I am still struggling to resolve the error on my own.
I recently started an Ionic project and followed this link to implement authentication using Angular.
Everything seemed to be working fine until I used the following code:
@Injectable({
providedIn: 'root'
})This resulted in the error:
Typescript Error
Expected 0 arguments, but got 1.I meticulously followed each step mentioned in the provided link, such as:
1: npm install npm@latest -g
2:
npm install -g @angular/cli, npm install @angular/cli3: ng update @angular/cli
However, upon trying the 4th step ng update @angular/core, I encountered this
Package "@ionic-native/splash-screen" has an incompatible peer dependency to "rxjs" (requires "^5.5.11", would install "6.4.0").Subsequently, when I executed ng update rxjs, I received this
Package "@angular/http" has an incompatible peer dependency to "rxjs" (requires "^5.5.0", would install "6.4.0").Moreover, updating http using ng update @angular/http led to another error message:
Package "@ionic-native/core" has an incompatible peer dependency to "rxjs" (requires "^5.5.11", would install "6.4.0").Consequently, I am at a standstill with upgrading @angular/core.
Additional note: As a newcomer to Ionic/Angular, I am unsure if the problem lies within the core version or elsewhere.
Note: I have attempted ng update, ng update --all, as well as clean uninstallation and reinstallation, to no avail.
