我已經嘗試了這個問題的幾乎所有解決方案，包括。 & lt的給定類型link rel="stylesheet" href= "。/style . CSS "/& gt；使用app.use(express.static('public '))等等，但我似乎找不到解決方案。

const provider =

},npm strat運行正常，應用程序運行正常，但是當我運行NPM build時，它顯示錯誤:
**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.**在網絡部分，我得到了以下內容:
對http://localhost:9000/bundle . js的確定響應
已取消:http://localhost:9000/style . CSS
救命啊！！
我添加了第二個答案，因為我認為可能會有不同的問題。我認為MIME類型錯誤可能是由于css路徑不正確。我認為它試圖提供一個錯誤，而不是不匹配MIME類型的css文件。嘗試從您的H TML模板中刪除以下行，并允許HtmlWebPackPlugin自動注入它。
<link rel="stylesheet" href="./style.css" />下面是我自己的webpack.config和index.html模板，希望對你有所幫助。

<link type="css" rel="stylesheet" href="src/node_modules/bootstrap/dist/css/bootstrap.css" crossorigin="anonymous">我認為這個問題是由于HtmlWebpackPlugin沒有為用minicsextractplugin注入的css文件提供mimetype。我已經通過使用HtmlWebpackLinkTypePlugin解決了這個問題，它應該將mimetype插入到css文件中。
/// top of file
const LinkTypePlugin = require('html-webpack-link-type-plugin').HtmlWebpackLinkTypePlugin;
....
const plugins = [
new CleanWebpackPlugin({

}),
new HtmlWebpackPlugin({
template: './src/index.html'
}),
new LinkTypePlugin({
'*.css' : 'text/css'
})
];這應該使您注入的樣式表行看起來像這樣:
<link rel="stylesheet" href="./style.css" type="text/css" />請注意*。css規則是一個glob，所以如果你的css文件存放在你的根目錄下，你需要添加類似**/*的東西。css作為你的規則。
希望這回答了你的問題。
我也有同樣的問題。解決方案只是等待一段時間，因為一些主機服務提供商在你更新后會有延遲。
我的問題是走錯了路。
運行npm后，運行構建
React創建靜態文件，但在index.html是類似href = & quot/static/CSS/main . 39c 237 F9 . chunk . CSS & quot；所以我在路徑的開頭加了一個點，變成了href = & quot。/static/CSS/main . 39c 237 F9 . chunk . CSS。
它似乎在VSCode或live server擴展中出現了錯誤
將現有的style.css名稱更改為abc.css，錯誤消失。
不確定是什么問題。
我記得之前偶然創建了一個名為style.css的文件夾，我已經刪除了
Vue.js與typescript應用程序。
過去幾個錯誤導致了你對我的誤解:
部署到新環境時，忘記修改vue.config.js中的“publicPath”。 所有css和js文件的生成文件路徑仍然指向先前環境中的路徑。
客戶端-app/vue.config.js
module.exports = {
publicPath: process.env.NODE_ENV === "production" ? "https://<yourUrlHere>" : "/",
chainWebpack: config => {在. ts文件中留下了注釋行，并收到了針對“app .& lt& gt。js '。 這個文件包含來自client-app/src/router/index.ts文件的內容，我在這里留下了許多注釋行。
