我使用离子6和Angular 12，我在浏览器上测试我的应用程序，它的工作正常，问题是当我尝试在模拟器或手机上测试它.我在chrome上检查它，它给我这些错误，在闪屏后，它给了一个空白屏幕.

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

这是我的index.html文件：

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="utf-8" />
  <title>Noz Terra</title>

 <base href="./">

  <meta name="color-scheme" content="light dark" />
  <meta name="viewport" content="viewport-fit=cover, width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no" />
  <meta name="format-detection" content="telephone=no" />
  <meta name="msapplication-tap-highlight" content="no" />

  <link rel="icon" type="image/png" href="./assets/imgs/nozterra1.png" />

  <!-- add to homescreen for ios -->
  <meta name="apple-mobile-web-app-capable" content="yes" />
  <meta name="apple-mobile-web-app-status-bar-style" content="black" />

</head>

<body>
  <app-root>
  </app-root>
</body>

</html>

这是我编译时在www文件夹中生成的index.html文件（我认为这是问题的根源）：

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="utf-8"/>
  <title>Noz Terra</title>

 <base href="./">

  <meta name="color-scheme" content="light dark"/>
  <meta name="viewport" content="viewport-fit=cover, width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no"/>
  <meta name="format-detection" content="telephone=no"/>
  <meta name="msapplication-tap-highlight" content="no"/>

  <link rel="icon" type="image/png" href="./assets/imgs/nozterra1.png"/>

  <!-- add to homescreen for ios -->
  <meta name="apple-mobile-web-app-capable" content="yes"/>
  <meta name="apple-mobile-web-app-status-bar-style" content="black"/>

<link rel="stylesheet" href="styles.css"></head>

<body>
  <app-root>
  </app-root>
<script src="runtime.js" type="module"></script><script src="polyfills.js" type="module"></script><script src="cordova.js" defer></script><script src="vendor.js" type="module"></script><script src="main.js" type="module"></script></body>

</html>
