Ember metal error on running ember test command

Hi, Here is a screenshot of errors I get when running ember test command.

Always I get that error about ember metal. Here is my ember version:

How can I fix this?

It is likely that one of your project dependencies requires updating. Known modules where this helps ember-i18n and liquid-fire

Thanks, So I will not use tests as we need i18n and they did not make any changes since last year.

You could possibly be missing the https://github.com/ember-cli/ember-cli-shims/ package. That one should provide the ember-metal import thingy do.

Hi, Is not that. We have ember-cli-shims and now it is last version.

Ok i’m out of ideas other than upgrading all of your packages :grin:

I asked this on other topic, but seems quite good here. It is a difference testing components when working with ember addon app or a real app ember new?
