I have the following code with a simple working Vue.js application. But the vue.js devtools is not responding. It was working well a few days ago, now it's not working anymore what could possibly be going wrong? when I go to https://chrome.google.com/webstore/detail/vuejs-devtools/nhdogjmejiglipccpnnnanhbledajbpd, it says it is already added.

  let data = {

  new Vue({

One alternative is to set up a local web server, as the OP already stated.
The other - which IMHO is faster and less harassing - is letting the extension have access to file URLs, which is disabled by default.

Simply go to chrome://extensions and leave the "Allow access to file URLs" box checked for Vue.js devtools.
