this.$q is undefined
-
Hi,
I’m trying to deploy a minimal app (it’s essentially the quasar-cli example) but I keep getting the error [Vue warn]: Error in data(): “TypeError: Cannot read property ‘screen’ of undefined”. The template at MayLayout.vue starts with
<q-layout>
. The trace shows the error is at QLayout.js, line 43:height: this.$q.screen.height,
As a test, I’ve replaced
<q-layout>
with<q-btn icon="help" />
. This gives [Vue warn]: Error in render: “TypeError: Cannot read property ‘platform’ of undefined” at QBtn.js, line 71:if (this.$q.platform.has.touch === true) {
So the obvious conclusion is that
this.$q
is undefined in those files, which I confirmed using the Chrome debugger. In the vue file, however,<div>{{ $q }}</div>
shows$q
normally.Do any of you know of any condition that would make
$q
unavailable to the Quasar modules?Any help is much appreciated. Thanks in advance!

@rubs I have seen sometimes when this happens, to remove node_modules / yarn.lock / package-lock.json and re-install yur node_modules and build again.
-
Actually I already did this, several times. I even cleared up all my global npm modules and reinstalled everything, to no effect. Thanks anyway!

@dobbel,
quasar info
shows this:What if you try it in a VM or other computer?
The project works in my colleague’s machine, so something must be different here. However I have many other Vue / Quasar projects and this is the only one with this kind of problem. (It’s the only one that uses
quasar-cli
. My other ones usevue-cli
and Quasar as a plugin).I can make the project available for testing if it helps.
-
One thing I notice: don’t use node 14.x with Quasar cli( that’s what I have been told). Use the latest 12.x.
Sure you can post a repo and I will take a look at it.

Okay, I’ll try going back to 12.x and I’ll let you guys know. Thanks for the time being.

I thought the problem was gone, but no. Going back to 12.x allowed the app to be built, but unfortunately it seems the problem is still there.

@rubs @Hawkeye64 @dobbel Any luck with this. I am having the same issue.
