Dealing with a few errors in Octopress after updating Ruby…

I (re-)installed GCC-4.9.2 a few days ago, and tonight when fired up Octopress (rake etc…) - ruby didn’t want to play. With my new GCC install I put gmp in another location, and ruby couldn’t find a the lib. So, I updated Ruby (ruby-2.2.2).

Download the source and compile it:

$ mkdir ruby-2.2.2_build && cd ruby-2.2.2_build
$ ../ruby-2.2.2/configure
$ make -j6
$ sudo make install

Updating gems (2.4.6)

$ sudo gem update --system

Ok, fine… Then:

$ rake preview
rake aborted!
LoadError: cannot load such file -- bundler/setup

Installing bundler again:

$ sudo gem install bundler

Then in the Octopress folder:

$ bundle install
Fetching gem metadata from https://rubygems.org/........
Fetching version metadata from https://rubygems.org/..
etc...

Now rake starts fine again.

$ rake preview

Octopress seems to work fine with ruby 2.2.2
