找不到模块@ angular / common / http Ionic 3 app

Question

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'

Answer 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

Answer 2

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.
