How to install Ember Validations?

1

I installed Ember Validations, by npm install. And got this issue when started ember server:

ENOENT, no such file or directory 'tmp/tree_merger-tmp_dest_dir-8WwxhLaL.tmp/ember-validations.js'

In package.json:

"ember-cli": "0.0.44",
"ember-validations": "~ 2.0.0"

What’s wrong here?

It could be that you are using such an old version of ember-cli. Is anything keeping you from upgrading?

Thanks, didn’t notice that.
