标签: contextify

在尝试编译标准的"Hello World"示例[2]时,我尝试在Windows 7 + Node.js平台上使用node-gyp失败[3].注意:当尝试npm install contextifyw或没有"-g"时,node-gyp以类似的方式失败[3] ,因此这些可能是相关的问题.

组态:

• node-gyp 0.12.2
• Windows 7 x64 SP1
• Python 2.7
• Node.js 0.10.24
• Visual Studio 2010 per [1](也尝试过2012)
• 每个[1] VS SDK 7.1(尝试过32位和64位版本)
• 从标准Windows命令提示符或SDK7.1 cmd提示符运行node-gyp

[3]"hello world"[2]项目中的"node-gyp rebuild"产生以下2个错误:

.... node-gyp\0.10.24\deps\uv\include\win.h(8738):错误C2371:'SYSTEM_POWER_STATUS':重新定义; 不同的基本类型[...\build\test.vcxproj]

以及2个警告:

我升级了节点并运行了"npm install -g contextify"看起来它安装得很好(没有错误),但输入"which contextify"什么都不返回.安装contextify时的消息:

我在使用npm安装contextify时遇到问题:

npm install -g contextify

并获取以下错误消息:

我尝试安装jsdom这样:

$ sudo npm install -g jsdom
# OR
$ sudo npm install    jsdom

在一些成功的命令之后,安装很快就会失败,第一条错误消息在[....]:

我想让jsdom工作:)

这是代码:

var jsdom = require("jsdom");
var request = require("request");
var fs     = require('fs');
var jquery = fs.readFileSync("./jquery-1.7.2.js", 'utf-8');

request({ uri:'http://nodejs.org/dist/' }, function (error, response, body) {
    if (error && response.statusCode !== 200) {
        console.log('HTTP request error... '+error);
    }
    jsdom.env({
        html: body,
        scripts: [
            jquery
        ],
        done: function(errors, window) {
            console.log('done');
        }
    });
});

这是错误:

jsdom.js:171
    features   = JSON.parse(JSON.stringify(window.document.implementation._fea
                                                          ^
TypeError: Cannot read property 'implementation' of undefined

我已经检查了是否提取了页面以及是否解析了jquery lib - 它们是.

我们可以看一下jsdom.js的实现:

[snip]
exports.env = exports.jsdom.env = function() {
    [snip] …

我进入NodeJS 1小时,所以请耐心等待.我的项目需要的一个软件包是JSDom.在激发了大部分互联网之后,我发现JSDOm有一个名为contextify的依赖项,它本身在JSDom安装中处理.所以这就是我的意思:

sudo npm install jsdom 

一切顺利,直到我得到以下内容:

gyp WARN install got an error, rolling back install
gyp ERR! rebuild error Error: EACCES, stat '/root/.node-gyp/0.8.2'

我有兴趣为一个项目做一些服务器端的DOM操作,所以我决定看看node.js,特别是在jsdom.我对node.js完全不熟悉,所以我的错误可能是显而易见的,但是我从来没有找到解决我问题的方法......

首先,我在本地运行Windows节点,并使用在线IDE cloud9

值得一提的是,因为我在安装最新的节点jsdom包(0.2.15)时遇到了麻烦,因为在Windows下无法编译所需的依赖性上下文(需要C++和Python,因为我发现npm不支持构建C++包) .所以我采取了两种替代方法:

1. 我安装了一个不依赖于contextify的旧版本,即jsdom@0.2.1.这是我目前拥有的npm列表

   ??? jsdom@0.2.1
     ??? cssom@0.2.5
     ??? htmlparser@1.7.6
     ??? request@2.10.0

   当我试图运行从jsdom github repo cloud9 采取的简单测试脚本时返回此警告

   The "sys" module is now called "util". It should have a similar

   我试图解决这个问题取代所有提到的sys到util,错误消失了......(仍然不太确定这是正确的事情,虽然......).所以,最后当我试图运行这个片段时

   var jsdom = require("jsdom");
   
   jsdom.env("http://nodejs.org/dist/", [
     'http://code.jquery.com/jquery-1.5.min.js'
   ],
   function(errors, window) {
     console.log("there have been", window.$("a").length, "nodejs releases!");
   });

   我发现了那个window.$ === undefined.试图在cloud9上运行节点v0.6.x和节点v0.4.x,在本地运行节点v0.8.7.

2. 我尝试做的另一件事是安装最新的jsdom@0.2.15,从这里获得编译的上下文,安装绑定并将其添加到contextify/node_modules,因为contextify依赖于它.我根本无法使它工作=(没有浪费太多时间,因为它似乎是一种错误的方法,并且上下文不是最新的.

   这是npm列表

   ??? jsdom@0.2.15
     ??? contextify@0.1.2
     ? ??? bindings@1.0.0
     ??? cssom@0.2.5
