Angular 2-导入html2canvas [英] Angular 2 - Import html2canvas

问题描述

我已经使用npm install html2canvas --save在angular 2项目上安装了html2canvas.如果现在转到任何文件并写入import * as html2canvas from 'html2canvas'，则会显示错误:

I have installed html2canvas on my angular 2 project using npm install html2canvas --save. If I now go to any file and write import * as html2canvas from 'html2canvas' it gives the error:

Cannot find module 'html2canvas'

我的软件包文件如下:

{
  ...
  "scripts": {
    ...
  },
  "dependencies": {
    ...
    "html2canvas": "^0.5.0-beta4",
    ...
  },
  "devDependencies": {
    ...
  }
}

我要导入html2canvas的文件是:

import { Injectable } from '@angular/core';
import * as jsPDF from 'jspdf';
import * as html2canvas from 'html2canvas';

@Injectable ()
export class pdfGeneratorService {

  ...
}

推荐答案

由于Angular2使用打字稿，因此您需要为该模块安装打字稿定义文件.

Since Angular2 uses typescript, you need to install the typescript definition files for that module.

可以从@types安装(如果存在).如果没有，则可以创建自己的定义文件并将其包含在项目中.

It can be installed from @types (if it exists). If it doesn't you can create your own definition file and include it in your project.
