I just found the answer here: https://github.com/quasarframework/quasar/issues/1616

“rwrz commented on 3 Sep •
For anyone appearing here, and is tired, and can’t find the reason, there are TWO plugin entries on quasar.conf.js, one for APP (where vuelidate should be) and one for BUILD (don’t put it here). Cya! ”

Hi Jenkin,

were you able to solve your issue?

I have the same problem. It does not recognize the plugin “vuelidate”.

As you, I followed the instruction here:
https://quasar-framework.org/components/form-validation.html

I receive the following error when running “quasar dev”

*ERROR Failed to compile with 1 errors
error in ./.quasar/import-quasar.js

Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: Unknown import from Quasar: vuelidate*

Thanks in advance for any help!
Andreas
