我引用https://www.npmjs.com/package/cordova-plugin-qrscanner并尝试在我的移动的应用程序中创建QR扫描功能。
因此，对于第一步，我将在ts文件中创建以下代码：

function onDone(err, status){

      if (err) {
       // here we can handle errors and clean up any loose ends.
       console.error(err);
      }
      if (status.authorized) {
        // W00t, you have camera access and the scanner is initialized.
        // QRscanner.show() should feel very fast.
      } else if (status.denied) {
       // The video preview will remain black, and scanning is disabled. We can
       // try to ask the user to change their mind, but we'll have to send them
       // to their device settings with `QRScanner.openSettings()`.
      } else {
        // we didn't get permission, but we didn't get permanently denied. (On
        // Android, a denial isn't permanent unless the user checks the "Don't
        // ask again" box.) We can ask again at the next relevant opportunity.
      }
    }

    QRScanner.prepare(onDone);

然而，当我尝试ng构建时，我遇到错误。
TS 2304：找不到名称'QRScanner'
