I am running Mountain Lion. After installing apple-gcc-4.2 using Macports (with a symlink to /usr/bin/gcc-4.2), rvm, ruby 1.9.3 and gem install rails, I received the error "Symbol not found: _rb_Digest_MD5_Finish (LoadError) Referenced from: /Users/userid/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/x86_64-darwin12.2.0/digest/md5.bundle" error when running 'rails new testapp'. I don't see this discussed anywhere and am completely stumped on how to proceed.
Any help would be much appreciated.
Thanks.

Check if C_INCLUDE_PATH is set. env | grep C_INCLUDE_PATH. If it is, remove it from your environment, and then rebuild Ruby.
Install XQuartz and try reinstall Ruby, and Rails
It will solve the 'darwin' problems

I tried running bundle install and it stopped on the json gem. So I tried running running sudo gem install json 1.7.3 which is the version that it crashed on it it gave the following:

ERROR: Error installing json:

I've tried making sure command line tools were installed, but I'm at a bit of a loss on how to get by this one.
Any help would be appreciated. Thanks
I was having a similar problem installing JSON 1.7.4 except I'm using RVM. Anyhow, what I did to remedy my problem was install Xcode 4.4 from developer.apple.com and once that was installed I had to install Xcode's command line tools. You can install the command line tools by launching Xcode then clicking Xcode > Preferences > Downloads and click install next to command line tools.
I eventually had to go to ruby 1.9.2 in order to make it work.
Upgrading from 1.9.3-p125 to 1.9.3-p194 did it for me.
It looks like Apple updated the Developer tools this month (August 2012)
I was hitting this problem and I just downloaded the latest Dev tools from https://developer.apple.com/downloads/index.action and now everything works.
I too had the same error message when trying to install Ruby On Rails on a Mountain Lion 10.8.2 system with Xcode 4.6.
A ruby version 1.8.6 is part of the normal OSX installation. After installation the command line tools in Xcode; as posted by Dwight Scott in this thread:
*launching Xcode then clicking Xcode > Preferences > Downloads and click install next to command line tools.*
The solution worked:
*<= 1.8.6 : unsupported
= 1.8.7 : gem install rdoc-data; rdoc-data --install
= 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!
Successfully installed json-1.7.6
Successfully installed rdoc-3.12.1
Successfully installed railties-3.2.11
Successfully installed bundler-1.2.3
Successfully installed rails-3.2.11

Thanks Dwight
Just updated the version of Ruby (1.9.2 to 1.9.3) I have installed but now getting the following error when running rake:
$ rake
-bash: /Users/mike.simmonds/.rvm/gems/ruby-1.9.3-p0/bin/rake: /Users/mike.simmonds/.rvm/rubies/ruby-1.9.2-p180/bin/ruby: bad interpreter: No such file or directory
Any tips?
It appears reinstalling the rake gem has fixed it.
looks like a gem pristine task failed and you had older rvm, I have already changed the upgrade code to run upgrade for every gem separately and report you list of failed gems.
It's important to read outputs of rvm, even we try to automate things and make things very easy - sometimes there is not much we can do with the available tools.
OSX Lion, Xcode 4.2, GCC 4.2
I get the following error installing bson_ext 1.4.1

I just ran into this. You should look in the mkmf.log file. Chances are, it's looking for GCC in the wrong place. I had to:
cd /usr/bin
sudo ln -s i686-apple-darwin11-llvm-gcc-4.2 i686-apple-darwin11-gcc-4.2.1
And all was well.
The accepted answer did not work for me. But this did.
I am using:

cd /usr/bin && sudo ln -s ./gcc gcc-4.2

So re-installing OSX lion fixed the problem. I guess uninstalling xcode 4.1 in the first place messed up my developer tools installation.
Thanks for the help.
I don't use XCode for anything but the developer tool binaries so I just uninstalled XCode:
sudo /Developer/Library/uninstall-devtools –mode=all
And then installed this:
https://github.com/kennethreitz/osx-gcc-installer
Fixed the problem right up and I saved some HD space to boot.
I'm a beginner programmer and I'm trying to get the rails server to run on OS X Lion. When I type "rails server" into the command line, I get this error:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:777:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError)

from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:1056:in `gem'
from /usr/bin/rails:18
What do you think a solution to the problem is? Any help you can provide would be greatly appreciated. Thanks!
You need to install the rails gem. You could probably do this by running bundle install inside that project.
Have you installed the Rails Gem?
gem install rails
Then do a gem list to see if Rails is in there.
It's also important that you be in the proper directory. So if you keep all of your apps in /apps/ make sure you are in /apps/my_app before calling the server command.
The Ruby bundled with OS X is too old for Rails 3.
I would recommended using 'rvm' to install the latest stable version of ruby-1.9.2-p260
Since installing ruby requires some compilation, make sure you have a gcc installed. You can install XCode to get an usable gcc.
To install rvm, you need bash, git and curl.
RVM: http://beginrescueend.com/
After that, you can use
gem install rails
Enjoy!
The Lion Server looks at a non-default path for the gem file
For example have a look at the first line of /usr/share/devicemgr/backend/devicemgrd:
#!/usr/bin/env GEM_HOME=/usr/share/devicemgr/webserver/gems GEM_PATH=/usr/share/devicemgr/webserver/gems RAILS_ENV=production /usr/bin/ruby
So to install the missing gems, make sure to install them at the required path:
sudo GEM_HOME=/usr/share/devicemgr/webserver/gems gem install rails
I am trying to get the Rails tutorial by Michael Hartl going. I spent a lot of time fighting various libraries. So I removed all ruby software from my Ubuntu 10.4 system.
Then I installed Ruby 1.9.2.
$ ruby -v
ruby 1.9.2dev (2010-07-02) [i486-linux]
So far so good. Then I did
sudo gem install rails
After a long time, it finished the installation.
Then I ran
$ rails -v
bash: /usr/bin/rails: /usr/bin/ruby1.8: bad interpreter: No such file or directory
So...I have no /usr/bin/ruby1.8 on my system. How do I get Rails 3.0.3 to use my ruby at /usr/bin/ruby?
I appreciate any help you can give me.
Just to see if I could keep going, I tried
$ cd /usr/bin
$ sudo ln -s ruby1.9.2 ruby1.8
This let me keep going, but is it the right thing to do?
It took trying 3 different methods of installing and uninstalling Ruby, but I finally got it!
I found a great tutorial by Toran Billups which gives some great instructions. After analyzing what he did, it comes down to a few key concepts:
Some libraries that are independent of the Ruby version must be installed in the system (using "sudo apt-get").
Use RVM to install Ruby in your own account. i.e. no "sudo".
Use gem to install gems in your particular ruby environment. (i.e. no "sudo"). When you set 1.8 as the Ruby environment, the gems are installed in the RVM 1.8 tree in your environment. When you set 1.9.2 as the environment, gems are installed in the 1.9.2 tree in your environment.
Here, then, is the process.
Remove all Ruby programs (1.8.x and 1.9.2) and Ruby libraries from your Ubuntu 10.4 system.
Install RVM on your system, following the instructions at the RVM site(broken) RVM site.
Follow Toran Billups' tutorial, starting at the point where you install Ruby 1.8.7.
Follow the instructions at Michael Hartl's tutorial(broken) Michael Hartl's tutorial to get Rails 3.0 working with Ruby 1.9.2, github, heroku.com, rspec, spork, and autotest.
I had the same error after installing with RVM and opening new shells. The solution was to run:
$ rvm use 1.9.2 --default
P.S.
I'm running Ubuntu 10.04 and after two days of trial and error finally got rails 3 working with ruby 1.9.2. I highly recommend using RVM to install ruby a godsend!
By the sounds of it Bash is finding ruby1.8 when its running the #!/usr/bin/env ruby line from the rails script, even though it doesn't exist. Try /usr/bin/env which ruby to see exactly what interpreter it's trying to load.
I was also having a headache with this, and don't want to use RVM right now.
I saw that the shebang line for /usr/bin/gem was #!/usr/bin/ruby1.8 and that this was presumably the issue.
I made sure /etc/alternatives pointed to the correct gem script; this can be set with:
update-alternatives --config gem
Then I removed /usr/bin/gem and symlinked from /usr/bin/gem to /etc/alternatives/gem
It turns out the only difference in the gem scripts was the shebang line, so manually changing that would have worked too.
Solved by changing back the version of my current Ruby (using RVM) to 2.0.x.
When i installed rails (two days ago) it was under the 2.0.0 version. Yesterday i changed to 2.1.x. Today i tried the rails command and got the error.
So turning back to the RVM Ruby version i installed rails did the trick.
Sorry by the bad english.
P.S. Using Ubuntu 13.10
