NPM version: can't change the language to non-English

HI!
In react.js I've this configuration:

    componentDidMount() {
        let lang;
        if (i18n.language=='en') 
            lang = 'en'
            else   
                lang = 'lt'
        console.log(lang);
        let outdatedBrowser = require("exports-loader?outdatedBrowser!outdated-browser/outdatedbrowser/outdatedbrowser.js")


        outdatedBrowser({
          bgColor: '#f25648',
          color: '#ffffff',
          lowerThan: 'borderImage',          
          languagePath: `node_modules/outdatedbrowser/outdatedbrowser/lang/${lang}.html`
        }); 
}

But message is always in English, while the default lang is lt. I've even removed all files from lang directory but message is still in English...
