Ruby developers - I need some help installing capybara gem

Hello all,

I am following along with the ODOT series and I need to install the gem nokogiri as it is a dependency of capybara. However, this is causing some issues. After I add the capybara gem:

group :development, :test do
  gem 'rspec-rails', '~> 2.0'
end

group :test do
  gem 'capybara', '~> 2.1.0'
end

...and then run bundle, I get an error telling me to make sure that gem install nokogiri -v '1.6.3.1' succeeds before bundling.

So I try doing what it says:

gem install nokogiri -v 1.6.3.1

...but then I get this output in my terminal:

ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied - /usr/local/rvm/gems/ruby-1.9.3-p392/gems/nokogiri-1.6.3.1/.autotest

I have also gotten this error:

I know other people have had a similar issue and have asked about it before in the forum, but nothing seems to work.

Any thoughts?

ps: I am running on a Mac OS X 10.9.4

I had a similar issue and got it to work by installing nokogiri using MacPorts. If you don't already have MacPorts installed:

http://www.macports.org/install.php

This will then give you the 'sudo port' command line tool needed to install nokogiri:

http://nokogiri.org/tutorials/installing_nokogiri.html

If that doesn't work let me know, otherwise there are some other package managers you can take a crack at as well.

Didn't seem to work, but just to make sure I did everything correctly:

1: Installed MacPorts for my version OS X

2: Agreed to Xcode license by running

sudo xcodebuild -license

3: Tried to install nokogiri using macports (but didn't work)

sudo port install libxml2 libxslt

As you can see I am still getting the same error I was before.
