Hey I get the following Error when i try to start the rails server

Any ideas? At the moment no possible solution worked...

By the way I run Windows 8... might be the problem at all :D

This morning, I'm facing the same issue too (Windows 7). Let me recommend to have a look here https://github.com/codahale/bcrypt-ruby/issues/72

I successfully fix my problem like this (updating my Gemfile):

gem 'bcrypt-ruby', '3.1.1.rc1', :require => 'bcrypt'

回答2:

If you have problems with the gem bcrypt, follow these steps:

1. Change to the gem directory found by bundle show bcrypt + ext\mri\, for example: c:\RailsInstaller\Ruby2.2.3\lib\ruby\gems\2.2.0\gems\bcrypt-3.1.10-x86-mingw32\ext\mri

2. run ruby extconf.rb

3. run make

4. make install

Note that this works only if your DevKit environment is correctly setup (run devkitvars.bat).

I encountered a similar issue but with Ruby 2.0 and Rails 3.2.15 on Windows. It now requires at least 3.1.2:

gem 'bcrypt-ruby', '~> 3.1.2'

Link: https://github.com/rails/rails/pull/12325

回答4:

Comment off "gem 'bcrypt-ruby', '~> 3.0.0'" in your gemfile this should be work

回答5:

The relevant version will constantly change. You can find the newest stable version number here: rubygems.org/gems/bcrypt-ruby

回答6:

If anyone is still having issues with this (especially with devise) on Windows 64 bit, try installing Ruby 64 bit, then rails as a gem (rather than using the rails installer) and then add: gem 'bcrypt-ruby', '~> 3.0.0', :require => "bcrypt"

You may need to change your tzinfo-data gem to: gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]
