Reacti18next無法從django將translation.json加載為json-有解無憂

React i18next 無法將 translation.json 加載為 json。在我使用構建檔案夾之前一切都運行良好

我正在使用 React / Django。

i18n.js：

import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';
import Backend from 'i18next-http-backend';
import LanguageDetector from 'i18next-browser-languagedetector';

// don't want to use this?
// have a look at the Quick start guide
// for passing in lng and translations on init

const Languages = ['ar', 'en', 'fr']

i18n
  .use(Backend)
  .use(LanguageDetector)
  .use(initReactI18next) // passes i18n down to react-i18next
  .init({
    lng: 'en',
    react: {
      useSuspense: true,
    },
    // the translations
    // (tip move them in a JSON file and import them,
    // or even better, manage them via a UI: https://react.i18next.com/guides/multiple-translation-files#manage-your-translations-with-a-management-gui)
    supported: ["en", "fr", "ar"],
    fallbackLng: "en",
    detection: {
      order: ['path', 'cookie', 'htmlTag', 'localStorage', 'subdomain'],
      caches: ['cookie'],
    },
    debug: true,
    whitelist: Languages,
    interpolation: {
      escapeValue: false, // not needed for react as it escapes by default
    },
    nsSeperator: false,
    keySeperator: false,
    backend: {
      loadPath: '/locales/{{lng}}/{{ns}}.json',
    },
  });

export default i18n;

index.js：

import React, {Suspense} from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import 'bootstrap/dist/css/bootstrap.min.css';
import './index.css';
import './i18n';

  ReactDOM.render(
    <React.StrictMode>
      <Suspense fallback={(<div className='index__loading'><h2>Loading...</h2></div>)}>
          <App />
      </Suspense>,
    </React.StrictMode>,
    document.getElementById('root')
  );

這是我在語言 loginheader.js 之間切換的地方：

import React, { Fragment, useEffect, useState } from 'react';
import './LoginHeader.css'
import { Link } from 'react-router-dom';
import { connect } from 'react-redux';
import { logout } from '../actions/auth';
import SortIcon from '@mui/icons-material/Sort';
import ExpandMoreIcon from '@mui/icons-material/ExpandMore';
import Alert from './Alert';
// import Drower from './Drower';
import Logo from '../assets/images/logo.png';
import { useTranslation } from "react-i18next";
import { FormControl, Select, MenuItem } from '@mui/material';
// import LanguageIcon from '@mui/icons-material/Language';
import i18next from 'i18next';
import cookies from 'js-cookie';

const languages = [
  {
    code: 'fr',
    name: 'Fran?ais',
    country_code: 'fr'
  },
  {
    code: 'en',
    name : 'English',
    country_code: 'en'
  },
  {
    code: 'ar',
    name: '???????',
    country_code: 'ly',
    dir: 'rtl'
  }
]

function LoginHeader({ logout, isAuthenticated }) {

  const currentLanguageCode = cookies.get('i18next') || 'en';
  const currentLanguage = languages.find(l => l.code === currentLanguageCode);
  useEffect (() => {
    document.body.dir = currentLanguage.dir || 'ltr'
    // document.title = t('app_title')
  },[currentLanguage]);

  const { t } = useTranslation()
  const [value, setValue] = useState('English')
  const handleChange = (event) => {
    setValue(event.target.value)
  }
  
  const guestLinks = () => (
