But running quasar commands like init still works fine.

Add this to your package.json, and recommending you to use yarn instead of npm:

"resolutions": {
    "ajv": "6.8.1"
  }

Note 1: this has been taken care of in the starter kit for any new projects. Note 2: not Quasar's fault for this issue, but unfortunately this is how things stand with npm packages.

@rstoenescu I have got the same issue while trying to upgrde my project from Angular 6 to Angular 8. I tried what you suggest, but did not work,

@rstoenescu I have the same issue, and like mentioned above, the issue still persists even after doing what you suggested.

[rstoenescu]

@peppeschiavo Angular????

@alice-0-kim use yarn and it'll work. unless something changed upstream again..

[yehee]

@rstoenescu Unfortunately, doesn't work with yarn as well..

@peppeschiavo Angular????

@alice-0-kim use yarn and it'll work. unless something changed upstream again.. @rstoenescu yes, Angular

I had the same problem but, when I manually installed ajv it worked fine.. Try this: npm i ajv
