I am currently trying to develop an app using Ionic 2 and Angular 2 with Typescript version . I decided to use the library amqp-ts to include messaging in my app. I installed the library via npm like:
npm install amqp-ts
Everything went fine and now I've got something like this:
/ app root directory
+ node_modules
- amqp-ts
- lib
- amqp-ts.d.ts
- node_modules
- amqplib
- bluebird
- winston
The problems begin now: I import the library into my component as it is done in the example of the documentation ...
import * as Amqp from "amqp-ts";
... and when I try to deploy the app I get the next error messages:
TypeScript error: C:/APPs/Test/Ionic2Angular2App/node_modules/amqp-ts/lib/amqp-ts.d.ts(2,26): Error TS2307: Cannot find module 'bluebird'.
TypeScript error: C:/APPs/Test/Ionic2Angular2App/node_modules/amqp-ts/lib/amqp-ts.d.ts(50,12): Error TS2304: Cannot find name 'Buffer'.
1. The line related to the first error message
// exported Typescript type definition for AmqpSimple
import * as Promise from "bluebird";
[...]
2. The line related to the second error message (same file: amqp-ts.d.ts)
export class Message {
content: Buffer;
[...]
}
I hope you can help me, please.
Additionally to regular package install you need to install TypeScript typings. Typings are like header files, they contain all methods/classes/interfaces definitions.
To install typings you need a typings tool. The best way is to install it globally so you can use it in every project
npm install typings --global
Then installing new typings inside your project is pretty simple, first search for library:
typings search bluebird
Install it :
typings install --save bluebird

I too faced same issue, but for me above answer is not working. While simply running:
npm i bluebird
resolving the issue
