回答1:

For those experiencing this issue after upgrading to @ionic/app-scripts : 3.1.0 you can fix it by, navigate to node_modules/@ionic/app-scripts/dist/template.js:153 and replace the line of code with this

return getTemplatePrefix(htmlFilePath) + "'" + content + "'" + getTemplateSuffix(htmlFilePath);

This was a manual fix for the bug but as of release. @ionic/app-scripts : 3.1.1 the bug was fixed.

After reading advice from Gerald Brigen and Suraj Rao, I looked at https://github.com/ionic-team/ionic/issues/13379.

Updated package.json app-scripts from 3.1.0 to 3.1.1. Removed that module and ran npm - i

"devDependencies": {
        "@ionic/app-scripts": "3.1.1",
}
