Error while trying to install ngx-translate

Ionic Framework ionic-v3
1

When executing the command:
npm install @ ngx-translate / core @ ngx-translate / http-loader --save

I get the error:

I already executed the command:
npm install -g rxjs@^5.0.1

With the log:

`- rxjs@5.0.1

And also the command:
npm install -g @ angular / cli

With the log:

When trying to import: @ angular / common / http in app.module.ts, I get the error: “[ts] Can not find module ‘@ angular / common / http’.”

If anyone can give me a solution, I would be extremely grateful.

I was able to solve by following the tips of this question (https://github.com/ngx-translate/core/issues/629). I will detail here, as it may be useful for someone facing the same problem.

Basically what I did, was to use the command:
npm install @ngx-translate/core @ngx-translate/http-loader@0.1.0 --save

Instead of the command:
npm install @ngx-translate/core @ngx-translate/http-loader --save

Described in Ionic’s ngx-translate documentation.
