Updating to latest beta-version crash the existing app:

[SharpBCD]

This is happening to me the 2nd time. On first update from beta-0 to beta-2 it was the same. Back then I deleted the app and regenerate it with quasar cli, moved the code and all was great.
This time I want to make it work, I can’t re-create the project every time. Any suggestion?
Note:

• I use npm.
• I tried to delete node_modules and install again, no effect.

Solved, thanks to Allan Gaunt (EN-GB) on discordapp.
Solution: remove node_modules folder
Reinstall using YARN and not NPM!

Sorry npm, you will no longer be trusted.

@SharpBCD consider using yarn for local and npm for globals
