LoadError：无法加载此类文件— bcrypt

Question

I am trying to use bcrypt to secure users password, but when i am creating new user in database i receive this error: "LoadError: cannot load such file -- bcrypt"

what i did till now:

1. i have placed a gem in the Gemfile gem 'bcrypt', '3.1.11'

2. i installed it sudo bundler install

3. bcrypt is in the gem list

 $ gem list bcrypt *** LOCAL GEMS *** bcrypt (3.1.11) 

4. i have restart the server

sudo service apache2 restart

5. i added new user in rails console

 $ rails console Running via Spring preloader in process 21100 Loading development environment (Rails 5.1.0) irb(main):001:0> User.create(username: "user1" , password: "pass123", password_confirmation: "pass123") You don't have bcrypt installed in your application. Please add it to your Gemfile and run bundle install LoadError: cannot load such file -- bcrypt from app/models/user.rb:2:in `<class:User>' from app/models/user.rb:1:in `<top (required)>' from (irb):1 

And as you see it didn't work!

6. i tried to uninstall and install bcrypt again => same result

7. i have tried other version of bcrypt => same result

8. i added bcrypt-ruby to gems => same result
9. i used gem install bcrypt --platform=ruby and gem 'bcrypt-ruby', '3.1.5', :require => 'bcrypt' => same result
10. i updated all the gems => same result
11. i built built native extensions manually

 cd [path to gems folder]/gems/bcrypt-ruby-2.1.4/ext/mri ruby extconf.rb make sudo make install 

=> same result

12. (waiting for your suggestion)

Answer 1

I solved the problem. i was searching for it almost 2 days!

kill all the processes with name spring using the pkill command as follows:

  $ pkill -15 -f spring

open a new terminal and : bundle exec guard is it gave you error "bundler: command not found: guard" dont worry. just be sure you have installed bycrypt by gem list bcrypt install bundle

sudo bundle install

then restart your server

sudo service apache2 restart

now it works!
