我正在使用角度2的最终版本,没有角度cli和webpack。
import * as d3 from 'd3'; //ERROR: Cannot find module 'd3'
我安装了d3: npm install d3 --save
问题是什么?
system.config.js:
/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.

(function (global) {
System.config({

// paths serve as alias

// map tells the System loader where to look for things
map: {

typings install --global --save dt~d3
您的代码中有一个JavaScript库(d3),并且您正尝试在TypeScript代码中导入它。 TypeScript不知道该库的“形状”,您需要安装TypeScript definition file才能使用它。它没有任何功能,只是库的“形状”,因此TypeScript编译器知道它正在使用它。
