PHPRad VUE PWA project creation

compiling the project with PWA gives me the following error

The same is for Python PWA and Desktop App. Even when the project is new and empty.
Worked with older versions (~ 3.6).

@Maxr167 you need to run this on the quasar command line. This seems to be a bug when you switch to a different platform, like Desktop, Mobile, or PWA. I will alert the dev about this.

quasar ext add @quasar/[email protected]

This is just a temporary fix, it means anytime you switch platforms you will have to run the command.

This happens not only with changing app, but also when one wants to add a library through npm …
I also solved it that way i:
quasar ext add @quasar/qcalendar
