Quasar: Compilation failure "dependency not found" objectSpread2

[mpacary]

Describe the bug
When doing quasar dev for a fresh empty project, I always get this error when the build process is around 50% done:

 ERROR  Failed to compile with 6 errors                                                                                                                         3:50:15 PM

This dependency was not found:

* C:\...\test\node_modules\@babel\runtime-corejs2/helpers/objectSpread2 in ./node_modules/quasar/src/ssr-update.js, ./node_modules/quasar/src/components/btn/QBtn.js and 4 others

To install it, you can run: npm install --save C:\...\test\node_modules\@babel\runtime-corejs2/helpers/objectSpread2

Build process then freezes.

Doing CTRL+C then running the suggested npm install command from the error message fails (could not install / error code ENOENT / -4058 / no such file or directory). Tried as well with yarn add, no luck.

I get a very similar issue & error message about "missing dependency .../objectSpread2" when running quasar build

N/A (CLI only)

To Reproduce
Steps to reproduce the behavior:

1. Create empty project with Quasar 1.0.3 & Quasar CLI 1.0.0 (quasar create), choosing default options
2. Go in project directory and run quasar dev

Expected behavior
Finish compilation/build, start browser etc. instead of giving an error message

More info on Mac OS :

When choosing npm for installation => exact same problem as reported above
When choosing yarn for installation (right after a fresh brew install yarn) => build process freezes at 0%

please update to @quasar/app v1.0.1 -> babel had a regression that's been
fixed.

Unfortunately still experiencing the problem even after upgrading quasar to v1.0.1.

Both quasar build and quasar dev fail on existing projet (there were working before) with errors in every Quasar component - example :

ERROR in ./node_modules/quasar/src/components/layout/QFooter.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
  ReferenceError: Unknown helper objectSpread2

Platform : Macos with npm

Delete node_modules folder and yarn.lock / package-lock.json and install again.

it worked. thanks for the fix and the amazing work on this great framework

[mpacary]

Thanks for your reactivity. I confirm that this is fixed with @quasar/app v1.0.1 (now default version with quasar create)

This is how we roll for critical issues.
