无法加载模块脚本：需要 JavaScript 模块脚本，但服务器响应的 MIME 类型为 "text/html"
Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html"
我在 kubernetes 上部署了我的 angular 应用程序（静态网页）并尝试从 Google Chrome 启动它。我看到应用程序正在加载，但浏览器上没有显示任何内容。检查浏览器控制台后，我可以看到这个错误
“加载模块脚本失败：需要 JavaScript 模块脚本，但服务器响应 MIME 类型为“text/html”。每个 [=] 对模块脚本强制执行严格的 MIME 类型检查41=] 规格。”
对于 (main.js,poylfill.js,runtime.js) 个文件。我研究了几个论坛，一个可能的根本原因可能是 <script> 标签中的 type 属性应该是 type=text/javascript 而不是我的 index.html 文件中的 type=module执行 ng build 后在 dist 文件夹下生成。我不知道如何对构建过程中生成的这些标签进行更改，我的 ng-build 命令由 docker 命令处理。
URL 我正在尝试访问的内容类似于：“http://xxxx:portnum/issuertcoetools
注意：主机 xxxx:portnum 也将被许多其他应用程序使用。
是否有解决此问题的方法或解决方案？

这个错误通常发生是因为你的部署是在一个子文件夹中，所以看起来 Angular 是直接从你的基础 URL 获取你的应用程序，所以你的 html 是在你去你的 domain.com/mysubfolder/index.html，但是 Angular 从 domain.com/index.html 而不是域获取你的资源。com/mysubfolder/index.html；我很确定这是您问题的原因。您可以通过以下方式解决构建您的应用程序的问题：
ng build --prod --base-href mysubfolder
我在 kubernetes 上部署了我的 angular 应用程序（静态网页）并尝试从 Google Chrome 启动它。我看到应用程序正在加载，但浏览器上没有显示任何内容。检查浏览器控制台后，我可以看到这个错误

这个错误通常发生是因为你的部署是在一个子文件夹中，所以看起来 Angular 是直接从你的基础 URL 获取你的应用程序，所以你的 html 是在你去你的 domain.com/mysubfolder/index.html，但是 Angular 从 domain.com/index.html 而不是域获取你的资源。com/mysubfolder/index.html；我很确定这是您问题的原因。您可以通过以下方式解决构建您的应用程序的问题：
ng build --prod --base-href mysubfolder
