我尝试开发一个Web扩展，我认为导入依赖项与其他任何javascript项目没有什么不同。例如，我使用名为languagedetect的软件包，它正常安装：
npm install languagedetect --save
（然后出现在package.json中）
但是我的内容脚本如下所示：
var LanguageDetect = require('languagedetect')
var lngDetector = new LanguageDetect()
console.log(lngDetector.detect('This is a test.'))
并且无法打印任何内容。
调试输出也不是非常有用的信息：
