Upgrade quasar – ReferenceError: process is not defined

I have a old project and I try to update this (quasar 1 to 2)
here the version I use:

at this point I have an error in my console from my browser:

Uncaught ReferenceError: process is not defined
    at eval (index.js:7:1)
    at ./src/router/index.js (app.js:282:1)
    at __webpack_require__ (app.js:1487:32)
    at fn (app.js:1785:21)
    at eval (app.js:23:79)
    at ./.quasar/app.js (app.js:19:1)
    at __webpack_require__ (app.js:1487:32)
    at fn (app.js:1785:21)
    at eval (client-entry.js:239:67)
    at ./.quasar/client-entry.js (app.js:30:1)

I tried to understand what Is missing but I’m a little lost

I have another error in the console maybe I don’t know if this have side effects or not but:

[Vue warn]: Failed to mount app: mount target selector "#app" returned null.

Sorry if the information is confuse, I’m also confuse where I need to check
