So, I got to the point where I wanted a clean slate so I reformatted and started my mac over with a clean install. I’m setting up things that I haven’t configured in a long time. It’s good for my memory though.

Problem #1 I’m running

bundle install

on ruby version 1.9.2 for a chef repository. It seems to have a problem installing the nokogiri gem. Nokogiri is a HTML, XML, SAX, and Reader parser.

An error occurred while installing nokogiri (1.6.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.2'` succeeds before bundling.

I take the advice and run gem install nokogiri -v '1.6.2' which fails because it can’t find the libiconv native library.

gem install nokogiri -v '1.6.2'

libiconv is a library that converts string encodings from or to unicode. libiconv comes standard on my mac, but for some reason nokogiri thinks it is missing.

So we need install libiconv again and tell nokogiri where libiconv is. Some options for installing libiconv are macports and brew. I installed with brew. And then ran.

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

This installed successfully. This fixed the problem in my development environment for my site, but for the chef repository, it still doesn’t recognize that nokogiri is installed.

Next, I ran

xcode-select --install

This installs the command-line developer tools for mac, which includes libiconv. Install nokogiri version as normal and that took care of the problem.
