Nokogiri gem not working

Question

I am using Rvm and ruby 2.1.5p273.

Installed nokogiri by: gem install nokogiri

It installs perfectly:

Successfully installed nokogiri-1.6.5
Parsing documentation for nokogiri-1.6.5
Done installing documentation for nokogiri after 3 seconds
1 gem installed

After typing:

gem list | grep nokogiri

I get: nokogiri (1.6.5)

This is all on Mac Yosemite.

require 'nokogiri'

shows: LoadError: cannot load such file -- nokogiri/nokogiri

I searched all over SO and other forums, for hours no solution is working.

gem env

gives:

Answer 1

Can you try the following stuffs:

brew update
xcode-select --install
brew install libiconv
brew link libiconv

Then try these:

 gem pristine nokogiri
 gem install nokogiri -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14
 or
 bundle install

Also please check if you are properly loaded your right gemset/ruby version.

Answer 2

I also had the same problem and just adding sudo worked perfectly fine with me

i.e Your command to install nokogiri is : gem install nokogiri now try adding sudo that will be like the following

sudo gem install nokogiri
