The thing is, this is the reason why the ember-cli is useful.
One of the issues I had when I first started out without it was never really knowing why it doesn’t work when it doesn’t. It could be anything, you might have left a bracket off somewhere - that could be enough to break it,
Ember-ckli has a load of tools included that will point out that sort of problem (most of the time), and tell you if you have put a file in the wrong place…etc
What is your reason to want to use such an old version, and your reason for not using ember-cli? I suspect you’ll have more hassle getting that to work than you would upgrading
