TypeError: Ember._setComputedDecorator is not a function about ember-decorators HOT 7 OPEN

The latest version of ember-decorators v5 should work.

@ember-decorators/argument is going to need some work to transition back to stage 1, it won't be usable with the polyfill unfortunately 😕

from ember-decorators.

problem is I am getting this error with ember-decorators => v5.2 and ember 3.9

i guess I will go back to ember 3.8 because this seems v6 like it is not really done yet ( integrated with ember 3.9 ) or polyfill

from ember-decorators.

v6 is complete and ready. @ember-decorators/argument, which is a separate library that isn't currently being maintained too much, is not ready unfortunately, but I recommend upgrading if you can.

from ember-decorators.

You may also want to run a yarn upgrade to ensure you have the latest version, because we fixed that bug with 3.9 in 5.1.4: https://github.com/ember-decorators/ember-decorators/blob/v5.1.4/packages/utils/addon/computed.js#L24

It's possible you have another addon including a different version of this addon

from ember-decorators.

ok .. sounds good but what about ember-data decorators ( where do i get those from ? ) with v6 and polyfil ?

from ember-decorators.

You can use DS.attr, DS.belongsTo, and DS.hasMany directly now.

class Person extends Model {
  @DS.attr() name;
}

Make sure you add parenthesis

from ember-decorators.

got it , thanks , might be good to slap that there in the docs ( the v6.0.0 release notes maybe )
