node.js - 使用 dc 和 Node.js 预渲染图表

Question

我正在尝试使用 npm 通过 dc.js 预渲染图表

但是当我在代码中包含 dc 时，它会抛出错误，我是 node.js 中的 nwebie，尝试搜索答案没有运气，可能应该是版本错误我了解到 jsdom 版本 > 1 没有 createWindow( )；方法，但更改版本并调用 npm install 和 update 也不起作用。任何帮助都非常感谢，提前感谢

我的package.json

{
  "name": "binode",
  "version": "1.0.0",
  "description": "binode testing",
  "main": "index.js",
  "scripts": {
    "start": "node index"
  },
  "author": "abc",
  "license": "MIT",
  "dependencies": {
    "body-parser": "^1.13.3",

    "dc": "^1.7.3",
    "express": "^4.13.3",
    "jsdom": "^1.5.0"
  }
}

错误:

我的简单js文件:

var express = require('express');
var app = express();
var d3 = require('d3');
var dc = require('dc');
var crossfilter = require('crossfiler');
var jsdom = require('jsdom');
global.d3 = d3;
var port = 2000;
app.listen(port,function(){
console.log("app listing port "+port)
});

我刚刚开始，它本身就抛出了错误

Answer 1

我尝试在node_modules/dc内运行npm install 然后又出现了一个问题index.js no dc is Defineed 添加 将 require('./dc') 更改为 dc =require('./dc') 现在它正在工作..
