  3. `bundle install`
  4. `plugin`ディレクトリに`redcarpet2_markdown.rb`を追加する(<a href="https://raw.github.com/nono/Jekyll-plugins/master/redcarpet2_markdown.rb" onclick="__gaTracker('send', 'event', 'outbound-article', 'https://raw.github.com/nono/Jekyll-plugins/master/redcarpet2_markdown.rb', 'Source Code');">Source Code</a>)
  5. `_config.yml`の`markdown: rdiscount`を以下のように修正する<figure class='code'> <figcaption>

## Pygment.rbの不具合

Snow Leopardだとなぜか<a href="https://github.com/tmm1/pygments.rb/issues/45" onclick="__gaTracker('send', 'event', 'outbound-article', 'https://github.com/tmm1/pygments.rb/issues/45', 'この問題');">この問題</a>に悩まされたため、この対応を実施しました:

> @mattwildig &#8211; thanks for posting your fix here. I was getting the same with Ruby 1.8, Pygments 0.5.0, and Python 2.6.1. Commenting out the relevant block in mentos.py fixed the issue for me (and now Jekyll works again &#8211; see mojombo/jekyll#1181).

具体的には`pygments.rb/lib/pygments/mentos.py`の<a href="https://github.com/tmm1/pygments.rb/blob/f82642a314bfc80088eea6e81df44b11e8d2193a/lib/pygments/mentos.py#L339-L343" onclick="__gaTracker('send', 'event', 'outbound-article', 'https://github.com/tmm1/pygments.rb/blob/f82642a314bfc80088eea6e81df44b11e8d2193a/lib/pygments/mentos.py#L339-L343', '以下の行');">以下の行</a>をコメントアウトしました:<figure class='code'> <figcaption>
