Reactjs - 加载翻译文件时出错答案

【问题描述】：

我一直在尝试开始一个新的 React 项目来练习一些技能。

最近我尝试通过添加react-i18next 和i18next 来添加国际化和本地化。

只需按照https://react.i18next.com 上提供的分步指南并添加我的翻译文件。

但是当我运行项目时，我得到控制台错误GET https://localhost:8080/locales/en/generic.json 404 (Not Found)

一开始我以为项目少了一个json-loader所以我加了webpack.config.js，结果还是一样。我检查了路径，一切似乎都正常。

提前致谢

i18n 文件

import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';

import Backend from 'i18next-http-backend';
import LanguageDetector from 'i18next-browser-languagedetector';

const fallbackLng = ["pt"];
const availableLanguages = ["pt", "en"];

const backendOptions = {
  loadPath: "/locales/{{lng}}/{{ns}}.json",
  crossDomain: true
};


i18n
  // load translation using http
  .use(Backend)
  // detect user language
  .use(LanguageDetector)
  // pass the i18n instance to react-i18next.
  .use(initReactI18next)
  .init({
    backend: backendOptions,
    fallbackLng,
    detection: {
      checkWhitelist: true,
    },
    whitelist: availableLanguages,
    interpolation: {
      escapeValue: false // react already safes from xss
    },
    ns: [
      "generic"
    ],
    defaultNS: "generic",
  });

export default i18n;

根文件

import './i18n';
import { I18nextProvider } from 'react-i18next';
import i18n from './i18n';


const App: React.FC = React.memo(() => {
  return (
    <AppContainer>
      <I18nextProvider i18n={i18n}>
        <Router>
          <React.Suspense fallback={<div>Loading...</div>}>
            <MainContainer />
          </React.Suspense>
        </Router>
      </I18nextProvider>
    </AppContainer>
  )
});

ReactDOM.render(<App />, document.getElementById('root'))

【解决方案1】：

所以我认为你找到了解决方案

我所做的只是添加 copy-webpack-plugin 并将以下代码放入我的 webpack 文件中

const common = {
  ...
  plugins: [
    ...
    new CopyPlugin([
      { from: "./src/locales", to: "locales" },
    ]),
  ]
}
