### What were you expecting?

I also get an error when trying to build dev. it MIGHT be related

These dependencies were not found:

* D:\...\imgalt\node_modules\webpack-dev-server\client\index.js?http://0.0.0.0:8080 in multi (webpack)-dev-server/client?http://0.0.0.0:8080 (webpack)/hot/dev-server.js ./.quasar/client-entry.js
* D:\...\imgalt\node_modules\webpack\hot\dev-server.js in multi (webpack)-dev-server/client?http://0.0.0.0:8080 (webpack)/hot/dev-server.js ./.quasar/client-entry.js
* D:\...\.quasar\client-entry.js in multi (webpack)-dev-server/client?http://0.0.0.0:8080 (webpack)/hot/dev-server.js ./.quasar/client-entry.js

To install them, you can run: npm install --save D:\...\imgalt\node_modules\webpack-dev-server\client\index.js?http://0.0.0.0:8080 D:\...\imgalt\node_modules\webpack\hot\dev-server.js D:\...\imgalt\.quasar\client-entry.js

What steps did you take, to get the error?

using a fresh install following this guide https://quasar-framework.org/guide/index.html
i just updated my NPM, Node, and yarn to latest versions today.
i cleared node cache
i deleted both global and project local node_modules

Hi,

Does the path to your project contains any exclamation mark as indicated? Webpack does not support that.
