Question

I’m trying to deploy my Rails app to my webhost (DreamHost) using Capistrano but it keeps failing because the various gems installed on the server are of a different version.

I can work around this by manually installing, one by one, the specific gem version when Capistrano complains about it.

There must be a better way.. is there something I can do so that when deploying, it automatically installs the different versions if required?

Answer 1

Yes there is, and it’s baked right into bundler…

You just need to add require 'bundler/capistrano' to your cap file and all should be fine from then on.

If all is not well you can try cap bundle:install manually to clear things up before install.
