Hi!
I´d like to contribute, but i don´t know, if that´s worth raising an issue:
WARNING in aurelia-dependency-injection Multiple versions of aurelia-dependency-injection found: 1.4.2 ./~/aurelia-dependency-injection 1.5.1 ./~/aurelia-validation/~/aurelia-dependency-injection
Regards
Probably a stupid question, but have you already cleaned up the package-lock.json? There might be specific version of aurelia-dependency-injection installed as dependencies of aurelia-validation which might be different than the global (app) one. Might be a good idea to delete the lock file and regenerate using npm i. That should fix such different version related problems.
No, not stupid question, very helpful. I forgot to clean it up. 
Thx!
