Fixing a "config.handlebars" undefined method error

Dev

I’m trying to run Discourse 1.4.5 in a dev environment. When I go to run bin/rake db:create db:migrate, it crashes with:

rake aborted!

I’m not a Ruby developer per se, so much of the Gem/bundler specifics are lost on me. Any ideas on how to debug or fix this? I’ve tried explicitly adding a require for ember/handlebars/template in config/boot.rb, but no avail.

In general we don’t do dev on old releases, is there a reason you are setting up a dev environment for stable?

Its possible one of the security backports broke the dev mode, try rolling them back to see if that is the case.

I’m trying to package Discourse as a Sandstorm app, which is why I picked stable.

When you say security backports, do you mean in Discourse or in its dependencies?

EDIT: I ran git checkout v1.4.0 and attempted running again, but still hit the same issue.

Hi @zombiezen, did you solve the problem? If so, how?

Never did. I gave up on packaging Discourse.
