在 angular4 应用程序中导入 xml2js

Question

I'm having problems using xml2js in my Angular4 Application.

I installed it via npm, and imported it like this:

import {parseString} from "xml2js";

But when I start my application, I get this error:

Failed to load resource: the server responded with a status of 404 (Not Found)
Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:3000/node_modules/xml2js

I also install typings.

I'm new to Angular (and Typescript), so i would be glad if someone could help me and explain what I did wrong :)

Answer 1

import * as xml2js from 'xml2js';

or

import { parseString } from 'xml2js';

If don't work, need run

npm install --save @types/xml2js

Answer 2

I imported the library exactly as you did with a clean project created using the angular cli and it imports and works fine.

If you are new to angular I would recommend using the official cli tool for setting up your project, it simplifies a lot of things related to importing packages.
