如何在尝试导入TypeError时修复“rule.assign :rule.assign不是函数”

Question

我可以毫无问题地import { ToastContainer } from 'react-toastify，但是当我尝试import 'react-toastify/dist/ReactToastify.css';时，我会得到一个错误：

./node_modules/next/dist/build/webpack/loaders/css-loader/src/index.js??ruleSet[1].rules[2].oneOf[7].use[1]!./node_modules/next/dist/build/webpack/loaders/postcss-loader/src/index.js??ruleSet[1].rules[2].oneOf[7].use[2]!./node_modules/react-toastify/dist/ReactToastify.css

TypeError: rule.assign不是一个函数

我使用next.js和顺风css，启用了jit模式。

_app.js：

import 'tailwindcss/tailwind.css';
import '../public/css/syles.css';
import NavBar from '../components/NavBar';
// dynamic(
//   () =>
//     import('!style-loader!css-loader!react-toastify/dist/ReactToastify.css'),
//   { ssr: false }             <== tried this as a potential fix, but didn't work.
// );
// import dynamic from 'next/dynamic';

import { ToastContainer } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';

function MyApp({ Component, pageProps }) {
  return (
    <>
      <ToastContainer position='top-center' />
      <NavBar />
      <Component {...pageProps} />;
    </>
  );
}

export default MyApp;

package.json：

  "name": "client",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "dev": "node server.js",

如有任何建议，将不胜感激。谢谢。

好的，所以我用{ injectStyle }来解决这个问题，并在useEffect()中执行。

我参考了这个页面：https://fkhadra.github.io/react-toastify/how-to-style/#inject-style-on-demand

_app.js：

import 'tailwindcss/tailwind.css';
import '../public/css/syles.css';
import NavBar from '../components/NavBar';
import { useEffect } from 'react';

import { ToastContainer } from 'react-toastify';
import { injectStyle } from 'react-toastify/dist/inject-style';

function MyApp({ Component, pageProps }) {
  useEffect(() => {
    injectStyle();
  }, []);
  return (
    <>
      <ToastContainer position='top-center' />
      <NavBar />
      <Component {...pageProps} />;
    </>
  );
}

export default MyApp;
