Problem at Build step from my cmd panel

[geoman2]

Hi I'm trying to install the app-framework from my cmd on my Win32 machine and I'm getting an warning at the Building development files - this may take a while ... step. The message is as follow: This file doesn't have an app associated with it for performing this action. Please install an app or, if one is already installed, create an association in the Default Apps Settings page. When accessing the localhost:1234 I get a Build error message: C:\Users\admin\my-app\node_modules\app-framework.cache\main.js:9:16: Cannot resolve dependency '......app/app.vue' at 'C:\Users\admin\my-app\node_modules\app-framework.cache......app\app.vue'

Can someone help with this?
