MIME类型('text/html')不是受支持的样式表MIME类型 [英] MIME type ('text/html') is not a supported stylesheet MIME type
问题描述
我已经尝试了几乎所有解决该问题的方法.
给出<link rel="stylesheet" href="./style.css" />使用app.use(express.static('public'))的类型以及更多其他内容，但看来我无法为此找到解决方案.
I have tried almost every solution for the problem which includes.
giving type for <link rel="stylesheet" href="./style.css" /> use of app.use(express.static('public')) and many more but it seems I am not able to find a solution for this.
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'))

npm strat运行正常，应用程序运行正常，但是当我执行npm run build时，出现错误:
npm strat is working fine the application is working fine, but when i do npm run build it gives me the error:
**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，我得到了以下信息:
In the network part I got the following:
Ok response for : http://localhost:9000/bundle.js
Ok response for : http://localhost:9000/bundle.js
cancled for : http://localhost:9000/style.css
cancled for : http://localhost:9000/style.css
帮助!!
推荐答案
我添加了第二个答案，因为我认为可能存在另一个问题.我认为MIME类型错误可能是由于CSS路径不正确所致.我认为它正在尝试提供错误而不是与MIME类型不匹配的css文件.尝试从HTML模板中删除以下行，并允许HtmlWebPackPlugin自动注入它.
I'm adding a second answer because I think there could be a different issue. I think the MIME Type error could be due to the css path not being correct. I think it is trying to serve up an error instead of the css file which is not matching the MIME type. Try removing the following line from your HTML Template and allowing the HtmlWebPackPlugin to inject it automatically.
<link rel="stylesheet" href="./style.css" />
下面是我自己的webpack.config和index.html模板，希望对您有所帮助.
Below is my own webpack.config and index.html template which I hope will help.
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' }
])
]
};
