我已经尝试了几乎所有的解决问题的方法,其中包括。给类型为<link rel="stylesheet" href="./style.css" />使用app.use(express.static('public'))和许多更多,但似乎我不能找到一个解决方案,这一点。

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>

  <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({

package.json脚本标签:

    "build": "cross-env NODE_ENV=production webpack --config webpack.config.js"
  },

npm strat运行正常,应用程序运行正常,但当我执行npm run build时,它给我错误:

**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

救命啊!!

我补充了第二个答案,因为我认为可能有不同的问题。我认为MIME类型错误可能是由于CSS路径不正确。我认为它是试图提供一个错误,而不是css文件,这是不匹配的MIME类型。尝试从HTML模板中删除以下行,并允许HtmlWebPackPlugin自动注入它。

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

下面是我自己的webpack.config和index.html模板,希望能有所帮助。

webpack.config

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

module.exports = {
    entry: './src/index.tsx',
    output: {
        filename: 'app/main.js'
    },
    devServer: {
        contentBase: './',
        watchContentBase: true
    },
    module: {
        rules: [
            {

                        loader: MiniCssExtractPlugin.loader,
                        options: {

                        }
                    },

                    "resolve-url-loader",

                        loader: "sass-loader?sourceMap",
                        options: {
                            includePaths: [
                            ],
                            sourceMap: true
                        }
                    }
                ],
                exclude: /node_modules/
            },

                },
                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' }
        ])
    ]
};

您可以尝试添加type属性:

<link type="css" rel="stylesheet" href="src/node_modules/bootstrap/dist/css/bootstrap.css" crossorigin="anonymous">
iswrvxsc

我认为这个问题是由于HtmlWebpackPlugin没有为使用MiniCssExtractPlugin注入的css文件提供mimetype。我使用HtmlWebpackLinkTypePlugin解决了这个问题,它将mimetype插入到css文件中。

/// top of file
const LinkTypePlugin = require('html-webpack-link-type-plugin').HtmlWebpackLinkTypePlugin;

....

const plugins = [
  new CleanWebpackPlugin({
    root: __dirname,
    verbose: true,
    dry: false
  }),
  new webpack.DefinePlugin({ 'process.env.NODE_ENV': '"production"' }),
  new MiniCssExtractPlugin({ filename: "style.css", allChunks: false }),
  new CopyWebpackPlugin([
    { from: './src/index.html', to: 'index.html' },
  ]),
  new webpack.ProvidePlugin({
    Promise: 'es6-promise-promise',
    'React': 'react'
  }),
  new HtmlWebpackPlugin({
    template: './src/index.html'
  }),
  new LinkTypePlugin({
    '*.css' : 'text/css'
  })
];

这应该使注入的样式表行看起来像这样:

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

需要注意的是,.css规则是一个glob,因此如果您的css文件托管在根目录下的目录中,则需要添加类似**/.css的规则。
我希望这能回答你的问题。

我也有同样的问题。解决方案只是等待一段时间,因为一些托管服务提供商在更新后会有延迟。

我的问题是走错了路。
运行npm run build
React创建了静态文件,但在index.html中,它类似于href="/static/css/main.39c237f9.chunk.css",所以我在路径的开头添加了一个点,成为href="./static/css/main.39c237f9.chunk.css

我记得有一个名为style.css的文件夹,我已经删除了之前意外创建的

Vue.js与typescript应用程序。
过去有几个错误导致了你对我的错误:
1.在部署到新环境时忘记修改vue.config.js中的'publicPath'。
生成的所有css和js文件的文件路径仍然指向以前环境中的路径。
client-app/vue.config.js

module.exports = {
publicPath: process.env.NODE_ENV === "production" ? "https://<yourUrlHere>" : "/",
chainWebpack: config => {

1.在.ts文件中留下注解行,并收到针对'app.<>. js'的错误。
这个文件保存了client-app/src/router/index.ts文件中的内容,我在那里留下了许多注解行。
