I was looking at replacing RVM with rbenv since I am using bundle to manage my gemfiles. rbenv, I believe, is a lot lighter in managing my Ruby versions, so I uninstalled RVM and installed rbenv. I installed the bundler gem using
gem install bundler
because we need it everywhere. Then I opened a project and installed the required version Ruby using rbenv:
rbenv install 1.9.3-p194
rbenv local 1.9.3-p194
rbenv rehash
I entered ruby -v to make sure it was using the right version of Ruby, and it was, so I tried running bundle and it ran until it tried to install RedCloth and and then failed:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/usr/bin/ruby1.9.1 extconf.rb --with-cflags=-w

from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from extconf.rb:1:in `<main>'
It suggested that I install RedCoth before bundling, so I installed RedCloth:
gem install RedCloth
which succeeded. I then ran ruby -v, just to make sure it's still right, then tried running bundle update and the same error occured:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing RedCloth (4.2.9), and Bundler cannot continue.
Make sure that `gem install RedCloth -v '4.2.9'` succeeds before bundling.
I then tried installing a different version of Ruby but had no success there either.
Does anyone have ideas?
I subsequently tried doing the same thing in my other projects and it all seems to work just fine. I have one that uses 1.8.7 and it was as easy as setting the rbenv to the right version and then running bundle. I tried almost every combination of Ruby version and yet it's not working.
I had a similar problem. It turned out that, even though I had the ~/.rbenv/shims directory at the front of my path, zsh was caching the location of bundle to /usr/local/bin/bundle.
The solution was simply running rehash at the shell (not rbenv rehash). This flushed all the cached commands, including bundle, and all went well after that.
I finally overcame the problem.
I had installed a wrong version of Ruby 1.8.7-p370. I then ran bundle and that had some gems compiling the native extensions against Ruby 1.8.7 when the bundle was for a 1.9.3 package, so even if I was to switch over to the 1.9.3 version and try running bundle again it would bomb out.
To fix this, I simply removed all the gems and then installed the right version of Ruby and then re-ran bundle.

I upgraded my environment from Ruby 2.0.0 to 2.2.3.
I also upgraded (overwrite) DevKit, and re-run ruby dk.rb install.
I removed Gemfile.lock and ran bundle install to start with a brand new environment. Everything looks ok, but I get the error:
E:\Projects\development\Stairs>rake db:migrate

I first had the same issue with Nokogiri, which I solved using this solution : Nokogiri load error
using Juloi Elixir's solution and installing Nokogiri from a local copy.
But I don't feel like doing this foreach gem! It looks like ruby is searching the gem using a ./ or ./2.2 path, while gems are stored in a ./2.2.0 path. Is this configurable?
How can I solve this issue?
Note: Gemfile contains gem 'bcrypt', '~> 3.1.10'
Thanks!
I spent an entire hour fixing this, just now.
Well what I did was I followed some advice online to do a
gem install bcrypt --platform=ruby
And then, it worked in irb.
irb(main):001:0> require 'bcrypt'
=> true
Later when I had to do a bundle install, for some odd reason rails installed another bcrypt and the error was back. So I had two folders in my gem root.
bcrypt-3.1.10
bcrypt-3.1.10-x64-mingw32
So, since the first folder was the one that got built with the devkit, and it works. I deleted the contents of the second folder and copied the contents of the first into it.
Seems to be working as I'm writing this.
Solution was here: bcrypt-ruby#github:
Rebuild locally the bcrypt gem:
Change to the gem directory \Ruby22-x64\lib\ruby\gems\2.2.0\gems\bcrypt-3.1.10-x64-mingw32\ext\mri>
Run ruby extconf.rb
Run make
Run make install
Note that this works only if your DevKit environment is correctly setup (run devkitvars.bat).
#user1185081 's solution worked for me in a windows machine. I ran following commands and worked like magic:
$ cd C:\RailsInstaller\Ruby2.2.0\lib\ruby\gems\2.2.0\gems\bcrypt-3.1.10-x86-mingw32\ext\mri
$ ruby extconf.rb
$ C:\<DevKit Path>\devkitvars.bat (assuming you have devkit installed)(Ran this instead of running "make" because it was not recognized as an internal or external command)
$ make install
What worked for me on Windows 7:
gem uninstall bcrypt to uninstall all versions of bcrypt, including those listed as dependencies
gem install bcrypt to reinstall
bundle install
In my case, a designating of the old version to bcrypt in Gemfile was a cause of the error. I removed a designating of the version and run bundle update bcrypt, then it was settled.
Here is the solution worked for me:
C:\> gem uninstall brcypt
C:\> gem install --no-ri --no-rdoc bcrypt
C:\> cd (path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri
C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> ruby extconf.rb
C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> make
C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> make install
I had the same problem:
cannot load such file — bcrypt_ext
Windows 8.1 64bit
ruby 2.3.3p222 (2016-11-21 revision 56859) [i386-mingw32]
Rails 5.1.4
My solution:
gem uninstall bcrypt-ruby
gem uninstall bcrypt
gem install bcrypt –platform=ruby
added this whole line to Gemfile:
gem 'bcrypt', git: 'https://github.com/codahale/bcrypt-ruby.git', :require => 'bcrypt'
bundle install
This works for me, add this to your gems file:
gem 'bcrypt', '~> 3.1.7', platform: :ruby

Either run a ruby from one of the environments you have mkmf in, or install the ruby-dev package on the system.
I'm trying to install Rails on Ubuntu 12.10 using the Ruby Version Manager. I believe that Ruby and RubyGems are installed correctly, and these are my versions:

gem -v: 1.8.23
I'm trying to install rails, using

Any idea what I'm doing wrong? If it helps, I'm trying to follow the tutorial at http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec-install_rails.
Thank you!
Install the gem as a normal user, not sudo:
gem install rails
Or install the ruby dev package. There are a lot of similar answers in SO:

Unable to install gem - Failed to build gem native extension - cannot load such file -- mkmf (LoadError)
Do you have a C compiler installed? If not, you should run sudo apt-get install build-essential to set up a compiler toolchain
I'm having problems when I try to rake db:migrate. I get the following error:
Could not find json-1.7.5 in any of the sources
Run `bundle install` to install missing gems.
Now, I've already run bundle install and it gave an error when it got to json, but I try it again anyway and get the same error when it gets to json:

I'm running Ubuntu 12.04LTS, ruby 1.9.3, rails 3.2.8, gem 1.8.15 (tried it with 1.9.1 also)
I think that you need to install the -dev package. Try running this command
sudo aptitude install ruby1.9.1-dev
and then bundle install should work.

I just saw this link, and not sure what to do with devkit*.exe files on ubuntu.
You are missing ruby-dev or ruby-1.9-dev package as described in this stackoverflow question. Install development package files first and then trying installing the gem.
I encountered the same issue and none of these fixes worked.
Here's what worked. It seems Ubuntu's .bashrc has this line near the top:
# If not running interactively, stop here.
[ -z "$PS1" ] && return
This, as the comment suggests, stops there. Capistrano executes the commands non-interactively, so when it runs .bashrc the rest of the file never gets sourced.
I had my RVM lines below this, so the environment wasn't set up properly for capistrano to bundle.
These lines should go above the previous line:
[[ -s "/usr/local/rvm/scripts/rvm" ]] && source "/usr/local/rvm/scripts/rvm"
Hope this helps someone.
