I'm trying to deploy my rails app on a VPS with capistrano and I am having this issue: Everything works well in development. Anyone knows how to approach this?

Can you post your Gemfile? Is active_admin inside a group (e.g. development) in your Gemfile? – Peter Goldstein
Thanks Peter. You pinpointed the exact problem. My activeadmin was misplaced in my assets group. I displaced and now it migrates properly. You rock! – Henri
@PeterGoldstein thanks! can you add it as an answer please so that i can upvote – Sahil Dhankhar
@SahilDhankhar Sure. Done. Thanks. – Peter Goldstein

If active_admin is located inside a group (e.g. 'development' or 'assets') and is not available in the production environment it can cause this error.
