问题
I have done the Ionic 3 app's internationalization using ngx-translate.It gave me below error.
I have done that using official doc here.
Cannot find module '@angular/common/http'
回答1:
The issue was @angular/common/http is only available in angular 4.3+.But on Ionic 3 we're using Angular 4.1.3.
So this is the solution:
I have removed @ngx-translate/http-loader
npm uninstall @ngx-translate/http-loader --save
And add an older version of it:
npm i @ngx-translate/http-loader@0.1.0 --save
You can read more about it on Git

HttpClient was introduced in Angular 4.3.0, you are using 4.1.3.
In the Angular version you are using you can inject Http (requires HttpModule in imports: [...] of AppModule), but it has different features and a different API.
