的JavaScript d3.csv（）给出了错误：读ECONNRESET

Question

我试图测试D3的d3.csv（）CSV阅读功能，但仍然收到错误

{ 'Error: read ECONNRESET': ' at exports._errnoException (util.js:1050:11)' }

我的测试脚本test1.js是反应app目录。

admin:reactStockCharts jvr23$ tree -L 1 
. 
├── BCHARTS-BITSTAMPUSD.csv 
├── README.md 
├── node_modules 
├── package-lock.json 
├── package.json 
├── public 
├── reactStockCharts.sublime-project 
├── reactStockCharts.sublime-workspace 
├── src 
└── test1.js 

测试csv文件BCHARTS-BITSTAMPUSD.csv驻留在同一目录中。内容如下：

Date,Open,High,Low,Close,Volume (BTC),Volume (Currency),Weighted Price

test1.js脚本内容：

var d3 = require("d3"); 

d3.csv("BCHARTS-BITSTAMPUSD.csv", function(err, data) { 
    console.log(err); 
    console.log(data[0]); 
}); 

执行该脚本然后给

admin:reactStockCharts jvr23$ node test1.js 
null 
{ 'Error: read ECONNRESET': ' at exports._errnoException (util.js:1050:11)' } 

D3的包经$ npm i d3之前成功地安装。

Answer 1

我能够用全路径规格更换

var d3 = require("d3"); 

d3.csv("BCHARTS-BITSTAMPUSD.csv", function(err, data) { 
    console.log(err); 
    console.log(data[0]); 
}); 

来解决该问题

var d3 = require("d3"); 

d3.csv("file:///full/path/to/BCHARTS-BITSTAMPUSD.csv", function(err, data) { 
    console.log(err); 
    console.log(data); 
}); 

Answer 2

var d3 = require("d3"); 

d3.csv("file:///full/path/to/BCHARTS-BITSTAMPUSD.csv", function(err, data) { 
    console.log(err); 
    console.log(data); 
}); 

是不是当你想在网上部署的解决方案，因为路径会改变。您应该使用相对路径，如下所述：https://coderwall.com/p/8nhqeg/relative-paths-from-the-root-in-javascript
