Update @vue-cli when installing v3
vue upgrade --all --next && npm dedupe
When doing vue upgrade --all --next && npm dedupe i get this:

I managed to make it work.
The fix for me was to manually install the latest vue/cli version:
npm install -g @vue/cli@next
If anyone has this issue, write here and i will try to help with more steps.

Thanks!
@LucianHij I did got exactly the same things as you, so i also update npm install -g @vue/cli@next but now i'm getting an error when running vue ~/.vuerc may be outdated. Please delete it and re-run vue-cli in manual mode . But I don't have any .vuerc in my project
@HippolyteQuief firstly start with a project from scratch just to be sure that you do not have any other problems with other versions.
So do
npm install -g @vue/cli@next
vue create my-app
cd my-app && npm run serve
And tell me if on a project from scratch you have the same error.
First I uninstall
Next install in global again
Just to you my version
When i try to run vue create

try to update to node 16.10.0, this is the version i used when i had success
I updated node to 16.0.0, install @vue/cli@next, until now everything is alright. But whenever i use vue i'm still getting the .vuerc error
Try
$ sudo npm uninstall -g vue
$ sudo npm uninstall -g vue-cli
$ sudo npm uninstall -g @vue/cli
$ sudo npm cache clean --force
$ sudo npm install -g vue
$ sudo npm install -g @vue/cli@next
Well, still not working, same error. I have a version where i can use vue3, typescript and vuetify.alpha-10, i will just continue on this one. Maybe it will work later when package will be updated
@LucianHij I found the .vuerc file ! it was in C:\Users\myusername
@HippolyteQuief great! Good job!
