Question

This question already has answers here:

can't activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.1. Make sure all dependencies are added to Gemfile (9 answers)

Closed 8 years ago.

When I try to run heroku run rake db:migrate I get this error:

can't activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.2. Make sure all dependencies are added to Gemfile.

I have updated my Gemfile and specified the version of bcrypt but has not worked. Everything is on the correct branch.

Gemfile:

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.0'
gem 'sass-rails', '4.0.1'

This is some useless text because stack overflow will not let me post with a small amount of text.
