Why does installing Nokogiri on Mac OS fail with libiconv is missing?

I had a similar issue and the accepted answer used to work for me. Now, however I have been seeing a new error message where a `gmkdir` command is missing as in this question:

What worked for me was first a little cleanup:

brew uninstall libiconv
brew uninstall libxml2
brew uninstall libxslt

And then `brew unlink libiconv` and whatever else you need to unlink (check with `brew doctor`). Then, the magic two lines (copied from the linked answer):

brew install coreutils
gem install nokogiri

Simple steps to follow before you start uninstalling and installing anything.
Check if you have CLT (command line tools installed):

`brew config`

see the CLT version here if its installed no need for reinstallation.

This means the issue is with permission you have reinstall only bundler gem make its not sudo.
Uninstall bundler with
`gem uninstall bundler`
reinstall gem bundler
`gem install bundler`

Most important point here is the permission under which bundler gem is installed it should never be sudoed.

`gem install nokogiri -v '1.6.6.2' -- --use-system-libraries --with-xml2-include=$(brew --prefix libxml2)/include/libxml2`

this worked for me on macos.
It works also with version `1.6.6.4`

I had the same issue. Unfortunately the "[Installing Nokogiri][1]" doesn't cover Iconv issues. Here's how I resolved the issue.

First install [homebrew][2], it'll make your life easier. If you already have it installed, be sure to grab the latest formulae by updating like so:

brew update

**Note**: In OSX 10.9+ you may need to install xCode command tools to allow you to install libiconv.

xcode-select --install

then install a newer version of libiconv

brew install libiconv


then install your gem

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