Answer 1

Uncomment this line of your Gemfile:
# Use ActiveModel has_secure_password
gem 'bcrypt', '~> 3.1.7'
and run bundle install again.

Answer 2

Remove all spring from your Gemfile.
gem "spring"
gem "spring-commands-rspec"
Run bundle install
Not sure why I tried to do another application with spring. :(

Answer 3

Run bundle update
I just experienced the same problem. I did what #Uday kumar das suggested and it worked perfectly!

Answer 4

It took me few hours to get this done but please feel free to share it.The root problem here is that Ruby itself comes with bcrypt version 3.1.5 which is having bugs with the newer updates.
However when you install or uninstall the bcrypt you are leaving behind bcrypt-ruby which it always asks for first and hence all what you are doing won't go through, so what to do?
uninstall bcrypt and bcrypt-ruby by running these two commands:
gem uninstall bcrypt and gem uninstall bcrypt-ruby
Install it again with:
gem install bcrypt --platform=ruby
In your Gemfile write:
gem 'bcrypt','~>3.1.11'
NOW as I write these lines the latest version is 3.1.11 but whatever version is updated just add it from their gem page. Run bundle install and it should work just fine.

Answer 5

I had the same problem. I fixed the problem by cloning the project into another folder and running bundle install in the newly cloned project. Then I was able to run the rails command again. Hope this helps.

Answer 6

I just had this same problem with bcrypt 3.1.12 after installing devise 4.6.2. I don't believe this is specific to crypt or devise, I believe this is a spring problem as others have indicated.
I was able to solve this problem simply by stopping spring and rerunning the rails generator with
spring stop
rails g devise:install
Try that before doing anything destructive or intrusive.

Answer 7

Add this line to your gemfile this code:
gem 'bcrypt'
and then run bundle install in console.

Answer 8

In my case, I uninstalled all versions of bcrypt, with gem uninstall bcrypt and select option 3 (if it exists), and uninstalled all versions of bcrypt-ruby gem with gem uninstall bcrypt-ruby and select option 3 (if it exists), then I installed bcrypt using gem install bcrypt --platform = ruby and I added this line gem 'bcrypt', '~> 3.1.7' in Gemfile. It worked right.

Answer 9

After search throught a lot of responses, for me this is the solution on Rails-5.0.2:
spring stop
bundle exec rake rails:update:bin
bundle exec spring binstub --all

Answer 10

gem pristine -a
bundle install
bundle update
solved this for me
I had these lines commented out as well due to a previous try, not sure if it helped.
# gem 'spring'
# gem 'spring-watcher-listen', '~> 2.0.0'
