npm将web3安装到Appcelerator Titanium SDK中> 6.x [英] npm install web3 into Appcelerator Titanium SDK > 6.x

问题描述

我想将web3安装到我的移动App项目中.

I would like to install web3 into my mobile App project.

但是，我在访问它时遇到问题，而没有出现很多红色屏幕，说我无法访问其中的这些文件.我试图手动更新路径等；

However I am having issues with accessing it without having a buch of red screens saying I can't access these files within it. I tried to manually update the paths etc;

我所做的是在我的App文件夹中:npm install web3

What I've done is in my App folder: npm install web3

然后我在App目录中看到node_modules文件夹...但是，我无法通过以下简单方法在我的index.js文件中要求该模块:

Then I see the node_modules folder in my App directory... however, I am not able to require the module in my index.js file with a simple:

var Web3 = require('web3'); // throws error
var web3 = new Web3();

function doClick(e) {
    var version = web3.version.api;
    $.label.text = "Web3 version: " + version;
}

$.index.open();

现在，我已将node_modules中的文件夹粘贴到我在App文件夹下创建的lib中，并尝试访问其中的dist以访问web3.min，然后尝试了很多其他操作，没有运气...还有其他人遇到过这样的问题或解决方案吗?

Now I've pasted the folder from the node_modules into a lib I created under App folder, and tried to access the dist within that to access web3.min, then tried a whole lot of other things, with no luck... has anybody else had such issue or have a solution?

推荐答案

该模块无法正常工作.从细微差异:

This module isn't going to work. From the Appc Node.js Support doc under minor differences:

SDK不能替代Node的核心模块

SDK doesn't have replacements for Node's core modules

我认为这实际上是一个主要区别，因为许多节点模块或其依赖项使用Node.js核心模块.例如，web3使用名为XMLHttpRequest的模块，该模块又使用Node.js核心 url 模块. Titanium将抛出一个错误，提示它找不到模块:体系结构的URL:x86_64".最可能还有其他几个核心模块依赖性.

I think this actually a major difference, as many node modules or their dependencies use Node.js core modules. For example, web3 uses a module called XMLHttpRequest, which in turn uses the Node.js core url module. Titanium will throw an error saying it 'couldn't find module: url for architecture: x86_64'. There are most likely several other core module dependencies.

至少目前，Node.js支持似乎最适合独立js库.考虑momentjs或underscore(尽管它们已经内置在Alloy中).

The Node.js support, at least currently, appears to be best suited for standalone js libraries. Think momentjs or underscore (though those are already built-in to Alloy).
