First of all, you should take a look at the Modules documentation for node.js: http://nodejs.org/docs/v0.5.5/api/modules.html
首先，您应该查看 node.js 的模块文档：http: //nodejs.org/docs/v0.5.5/api/modules.html
The script you're trying to include is not a node.js module, so you should make a few changes to it. As there is no shared global scope between the modules in node.js you need to add all the methods you want to access to the exports object. If you add this line to your latlon.js file:
您尝试包含的脚本不是 node.js 模块，因此您应该对其进行一些更改。由于 node.js 中的模块之间没有共享的全局范围，因此您需要将所有要访问的方法添加到导出对象中。如果将此行添加到 latlon.js 文件中：
exports.LatLon = LatLon;
...you should be able to access the LatLon function like this:
...您应该能够像这样访问 LatLon 函数：
var LatLonModule = require('./lib/latlon.js');
var latlongObj = new LatLonModule.LatLon(lat, lon, rad);
