For some reason when i enter

$ bundle install

it outputs this (Nokogiri is not in this gemfile). I am new to mac so it could be something to do with rvm.

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 even tried following the directions on the nokogiri website (even though it wasn't in this gemfile) but it still didn't work. I also even tried commenting out nokogiri in a different gemfile to see if that was the problem but still no success.

UPDATE For somereason now in this directory it is giving me, "Rails is not installed on this computer" however if i cd out of this directory and type rails -v it works fine.

  • maybe try deleting Gemfile.lock – James May 23 '14 at 05:37
  • I've seen that there is other question like yours with same [error](https://stackoverflow.com/questions/12657558/installing-nokogiri-mac-os-x-10-8-2-xcode-installed). Was answer there helpful for you? – Milos Dolobac May 23 '14 at 05:44
  • Are you install runtime dependency gem `mini_portile` – Antony Mithun May 23 '14 at 06:01

  • @manu29.d Thanks, I have already had a look and tried those methods same with Milos. Any other ideas on how I could fix this error? For some reason now only in this directory it is saying that rails is not installed? – HarryLucas May 23 '14 at 08:56

There are dependency gems which you don't include in the gemfile, several gems use dependency gems for their operation, e.g. devise gem, you only include this gem into your gem file but it has dependency gems which get installed along with devise gem, you can check dependency gems in your Gemfile.lock file, here's the example for devise gem

devise (3.2.0)
  bcrypt-ruby (~> 3.0)
  orm_adapter (~> 0.1)
  railties (>= 3.2.6, < 5)
  thread_safe (~> 0.1)
  warden (~> 1.2.3)

bcrypt-ruby and other gems are dependency gems here

First of all, bundler also (always) installs any requirements of all gems you want to install. To see which gem requires nokogiri, take a look at Gemfile.lock, as this gives a complete list of all installed gems, versions and their requirements (including versions)

To solve your problem, you should install libiconv as stated in the error message.

  • I tried installing libiconv and then linking it but I am still getting the error – HarryLucas May 23 '14 at 08:53
  • Have you tried installing nokogiri using system libraries by calling `bundle config build.nokogiri --use-system-libraries` before `bundle install`? – Peter Sorowka May 23 '14 at 12:08
