Gem Nokogiri error

Getting this error when I try to bundle after saving the new gemfile

Errno::EACCES: Permission denied @ rb_sysopen - /Users/ajnandi/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/nokogiri-1.6.2.1/.autotest An error occurred while installing nokogiri (1.6.2.1), and Bundler cannot continue. Make sure that gem install nokogiri -v '1.6.2.1' succeeds before bundling.

I then install that gem, but nothing happens and the same error comes up

[Nokogiri Mavericks Fix]

This worked for me:

[Step 1]

Open your terminal and enter this command:

 xcode-select --install

[Step 2]

Make sure you have Homebrew installed like so:

Enter this command on your terminal:

 brew install wget

[Step 3]

Enter this command:

This installs a necessary library for Nokogiri.

brew install apple-gcc42

[Step 4]

Install Nokogiri

sudo gem install nokogiri

try sudo gem install nokogiri -v '1.6.2.1'. I feel that it might a problem with the permissions with your folder.

Hi, may be late but I had this issue and it was because I hadn't installed the Xcode command tools mentioned earlier as it didn't error on the creation of odot. I now have a different error but I hope this helps. :)
