Compass Compile error when pushing to heroku

[imack]

I'm trying to use ember-cli-compass-compiler package with ember-cli-rails, but I get a problem when I try and push to Heroku: Your Ruby version is 2.2.6, but your Gemfile specified 2.3.3 (Bundler::RubyVersionMismatch). It seems to use a different version of ruby than the one from my Gemfile, even when I override the compassCommand option for ember-cli-compass-compiler to use bundle exec.

For ember-cli-rails, the ember assets are compiled as part of the Rails asset precompile, but for some reason it seems to use the wrong ruby version, any thoughts?

[quaertym]

Do you get any error without overriding compassCommand?

[imack]

@quaertym yeah; got the same error. I suspect it might have something to do with the exec creating a new shell where the Heroku Ruby version isn't set.

[quaertym]

exec is used here: https://github.com/quaertym/compass-compile/blob/master/lib/compass.js#L25
