[SOLVED] Downgrade rails gem with Rubber

Downgrade rails gem with Rubber

I have a rails gem that I need to downgrade to an older version due to an issue with the newer version: aws-sdk

I've updated my local Gemfile and pushed to my git server to:

gem 'aws-sdk', '< 2.0'

Now, I need to get my production server updated with the downgraded gem, instead of the newer version that it currently has.

I tried cap deploy, but am getting this error:

 ** [out :: app01-myserver.com] You are trying to install in deployment mode after changing
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] your Gemfile. Run `bundle install` elsewhere and add the
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] updated Gemfile.lock to version control.
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] You have added to the Gemfile:
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] * aws-sdk (< 2.0)
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] You have deleted from the Gemfile:
 ** [out :: app01-myserver.com] * aws-sdk

So, is there a cap or rubber command that I can run from the command line that will update the Gemfile?

Solution

As described in error message, you should add your Gemfile.lock to git. After it just run bundle update aws-sdk, commit changes in Gemfile.lock, push it and deploy to the production server using cap.
