我正在嘗試從用 Go 編寫的服務(wù)器提供 Angular 應(yīng)用程序（Angular 8.2.14）。四處搜索后，我發(fā)現(xiàn)了以下片段，據(jù)說可以解決這個問題。func main() {    http.ListenAndServe(":4000", http.FileServer(http.Dir(folderDist)))}其中folderDist是我構(gòu)建應(yīng)用程序的目錄。當(dāng)我在示例中導(dǎo)航到 localhost:4000 時，我在瀏覽器上收到以下錯誤：runtime-es2015.js:1 Failed to load module script: The server responded with a non-JavaScript MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec.styles-es2015.js:1 Failed to load module script: The server responded with a non-JavaScript MIME type of "text/plain".

Strict MIME type checking is enforced for module scripts per HTML spec.vendor-es2015.js:1 Failed to load module script: The server responded with a non-JavaScript MIME type of "text/plain".
