title: Vue.js with webpack: How to fix ERROR EBUSY: resource busy or locked
body: <p>I have several Vue 2 &amp; 3 and Quasar based projects that have been working like a charm. Suddenly all of them broke. Now each time I alter some code in an app it breaks with an error in the console <em>for example</em>:</p>
  <pre><code>[webpack-dev-server] ERROR in ./src/pages/Main.vue
  Module build failed (from ./node_modules/vue-loader/dist/index.js):
    Error: resource busy or locked, open 'D:\www\vue\myApp\sr  c\pages\Main.vue'
  </code></pre>
  <p>This happens with <strong>every</strong> vue component I try to change. After searching in the web I found a lot about similar errors arising in other frameworks and tried to follow the advises but without success. I created several new default apps but they behave in the same way. Did I break some piece of code in my PC elsewhere? How can I restore normal operation?
  Please, help.</p>
