Problem deploying with Pistrane

Question

I am having a very strange problem with Pistrano at the time of deploying to my staging environment. I am using Ruby 2.0.0, Rails 4.2.3 and Capistrano 3.4.0. My server environment is ready, however when I give a cap staging deploy, the process runs normally until I get this error:

NameError: uninitialized constant ActionView::Helpers::ActiveModelHelper

I notice that it is related to the precompile, since in the lines that precede the error, I see:

Tasks: TOP => deploy:assets:precompile

I tried to change the Rails version to 4.2.0, but the problem keeps happening the same way.

Would anyone know to tell me what might be wrong?
