用来帮助你加载你自己的模块的帮助模块

这是为Node.js插件模块的作者提供的辅助模块。它基本上是查找你编写的插件模块中.node文件的“瑞士军刀”。

在Node的插件历史过程中，插件最终会在各种不同的位置进行编译，具体取决于使用的构建工具和Node版本。更糟糕的是，现在gyp构建工具可以生成Release或Debug构建，每个构建都构建在不同的位置。

此模块检查将在其中构建本机插件的 所有 可能位置，并返回 第一个 成功加载的位置。

安装

npm install bindings

范例

require()为当前节点版本，平台和体系结构提供正确的绑定文件非常简单：

var bindings = require('bindings')('binding.node')

// Use your bindings defined in your C files
bindings.your_c_function()

漂亮的错误输出

当无法加载.node文件时，node-bindings会抛出一个错误，并显示一条很好的错误消息，告诉您确切的尝试内容。您还可以检查err.tries 属性。
