我已经尝试了几乎所有解决问题的方法，其中包括。为 <link rel="stylesheet" href="./style.css" /> 提供类型使用app.use(express.static('public'))还有更多，但我似乎无法为此找到解决方案。

index.js :

import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux'
import "./assets/styles/app.less";
import 'bootstrap/dist/js/bootstrap.js';
import App from './components/base/App';
import store from './store'

const provider =
  <Provider store={store}>
    <App />
  </Provider>

render(provider, document.getElementById('my-app'))

index.html :

<!DOCTYPE html>
<html>

<head>
  <meta http-equiv=X-UA-Compatible content="IE=edge,chrome=1">

  <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
  <link rel="stylesheet" href="./style.css" />
</head>

<body>
  <div id="my-app"></div>
  <script type='text/javascript' src="./bundle.js"></script>
</body>

</html>

webPack.config.js :

'use strict';
const webpack = require('webpack');

const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const CopyWebpackPlugin = require('copy-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin')

const plugins = [
  new CleanWebpackPlugin({
    root: __dirname,
    verbose: true,

package.json 脚本标签:

"scripts": {
    "start": "webpack-dev-server --content-base dist/ --port 9000 --config webpack.config.js --watch --progress --inline --hot --history-api-fallback --mode development",
    "build": "cross-env NODE_ENV=production webpack --config webpack.config.js"
  },

npm strat 工作正常应用程序工作正常，但是当我执行 npm run build 时它给了我错误:

**Refused to apply style from 'http://localhost:9000/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.**

**Refused to execute script from 'http://localhost:9000/bundle.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.**

在网络部分我得到了以下内容:

Ok response for : http://localhost:9000/bundle.js

cancled for : http://localhost:9000/style.css

求助!!

最佳答案

我添加了第二个答案，因为我认为可能存在不同的问题。我认为 MIME 类型错误可能是由于 css 路径不正确造成的。我认为它试图提供一个错误而不是与 MIME 类型不匹配的 css 文件。尝试从您的 HTML 模板中删除以下行并允许 HtmlWebPackPlugin 自动注入(inject)它。

<link rel="stylesheet" href="./style.css" />

以下是我自己的 webpack.config 和 index.html 模板，希望对您有所帮助。

webpack.config

const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const HtmlWebpackPlugin = require('html-webpack-plugin');
const LinkTypePlugin = require('html-webpack-link-type-plugin').HtmlWebpackLinkTypePlugin;
const CopyPlugin = require('copy-webpack-plugin');

module.exports = {
    entry: './src/index.tsx',
    output: {
        filename: 'app/main.js'
    },
    devServer: {
        contentBase: './',
        watchContentBase: true
    },
    module: {
        rules: [
            {
                test: /\.scss$/,
                use: [{
                        loader: MiniCssExtractPlugin.loader,
                        options: {

                        }
                    },
                    "css-loader",
                    "resolve-url-loader",
                    {
                        loader: "sass-loader?sourceMap",
                        options: {
                            includePaths: [
                            ],
                            sourceMap: true
                        }
                    }
                ],
                exclude: /node_modules/
            },
            {
                test: /\.tsx?$/,
                use: {
                    loader: 'babel-loader'
                },
                exclude: /node_modules/
            },
            {
                test: /\.(eot|svg|ttf|woff|woff2)$/,
                loader: 'file-loader',
                options: {
                    publicPath: "./",
                    outputPath: "app"
                }
            }
        ]
    },
    resolve: {
        extensions: ['.tsx', '.ts', '.js']
    },
    plugins: [
        new MiniCssExtractPlugin({
            filename: './app/style.css',
        }),
        new HtmlWebpackPlugin({
            template: 'index.html'
        }),
        new LinkTypePlugin({
            '**/*.css' : 'text/css'
        }),
        new CopyPlugin([
            { from: 'assets', to: 'assets' }
        ])
    ]
};
