我正在尝试运行节点脚本和 html 页面,但我不断收到错误消息。我试图运行的脚本是:
node script.js page.html
script.js 文件具有以下内容:
var argv = require('optimist').argv,
$ = require('jquery'),
fs = require('fs');
var file = argv._[0];
var html = fs.readFileSync(file, 'UTF-8');
$(html).find('p').each(function(index) {
var content = $(this).html();
console.log('Paragraph ' + (index + 1) + ': ' + content);
});
我的 page.html 有以下代码:
<html>
<body>
<p>Apple</p>
<span>Unrelated</span>
<p>Orange</p>
<div>Steak</div>
<p>Banana</p>
</body>
</html>
我的 packages.json 文件内容如下:
{
"name": "paragraphs",
"version": "1.0.0",
"main": "script.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"dependencies": {
"optimist": "0.3.4",
"jquery": "1.7.3"
},
"author": "Joe LeBlanc",
"license": "BSD"
}
我安装了 jquery 和 optimist 模块,但我不断收到以下错误:
C:\Documents and Settings\Amen.Ra\Desktop\paragraphs\node_modules\jquery\lib\node-jquery.js:10
window.XMLHttpRequest.prototype.withCredentials = false;
TypeError: Cannot read property 'prototype' of undefined at create (C:\Documents and Settings\Amen.Ra\Desktop\paragraphs\node_modules\jquery\lib\node-jquery.js:10:26)

是什么导致了这个错误
