uninitialized constant ActionView::Helpers::Active

问题:

I am trying to deploy my rails app on openshift, but i get this errors. Phusion Passenger show this error: You have already activated rack 1.5.2, but your Gemfile requires rack 1.6.0. Using bundle exec may solve this. (Gem::LoadError)

回答1:

actionpack 4.2 needs rack ~> 1.6.0. Your Gemfile probably does not include rack gem. You can try adding this line to your Gemfile

gem 'rack', '~> 1.6.0'

and then run

bundle install  

and

git push origin

This might force the openshift environment to use latest rack gem.

回答2:

OpenShift is internally dependent on RHEL 6.6 SCL ror40 which includes rack version 1.5.2 and passenger 4.0.18. Unfortunately none of this cannot be updated as for today.

回答3:

As a beginning troubleshoot step rename Gemfile.lock (or delete it) and then reinstall your bundle bundle install
