block in replace_gem can't activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.1

问题

I've looked at several answers regarding this problem and none seem to do the trick. This is on windows and I am lost for ideas. Thanks for the help!

I just solved the same problem on my project.

The problem is that in version 3.1.1 the method 'has_secure_password' is not supported, so calling it in your model while in version 3.1.1 will not work. However, as mentioned here -> bcrypt error: Devise ruby 2.0 and rails 4.0, simply specifying a version in the gemfile won't work, because a windows compatible version will be used, which causes it's own issues.

My solution was to fork the bcrypt-ruby's github repo, then roll it back to 3.0.1 version and use that as the source for the gem, like this:

gem 'bcrypt-ruby', git: 'git@github.com:hananamar/bcrypt-ruby.git', :require => 'bcrypt'

You're invited to use my repo :)

Hopefully these issues will be fixed soon.
