我开始作出反应，原产于代码，并在尝试使用ReactLocalization库即时得到下面的错误代码时：阵营本地LocalizedStrings.js - 未定义不是对象
undefined is not an object (evaluating 'localization.language')

我我试图研究，但由于框架是新的方式，没有太多的信息。
预先感谢您！
编辑：这里是类代码

/**
* Simple module to localize the React interface using the same syntax
* used in the ReactNativeLocalization module
* (https://github.com/stefalda/ReactNativeLocalization)
*
* Originally developed by Stefano Falda ([email protected])
*
* It uses a call to the Navigator/Browser object to get the current interface language,
* then display the correct language strings or the default language (the first
* one if a match is not found).
*
* How to use:
* Check the instructions at:
