Two versions of gems in production rails deploymen

I think i have some issues with my gemfile in production, as it differs from my development, which i believe is causing my deployment (Capistrano) to fail, well at bundle install time at least

The problem i am getting is when deploying the application cannot find the will_paginate gem. Am i correct in saying that it looks like i have two gemsets trying to work here? Im not quite sure, dont want to mess up my production environment so thought best to get some advice on this one

回答1:

If it is working in development environment in your machine, then i think you should push your Gemfile.lock along with your code and deploy the application. Then "bundle install" in your production environment also installs the same gems versions as in your development environment.

回答2:

You need in your deploy.rb

require "bundler/capistrano"

set :bundle_cmd, '/path/to/bundle'

So bundler will install all necessary gems automatically.

Otherwise you need to do it manually.
