jekyllのPygments

python2ディレクトリがないというので、無理矢理にpythonにした。ヒドイ解決だ。

    # Detect a suitable Python binary to use. We can't just use `python2`
    # because apparently some old versions of Debian only have `python` or
    # something like that.
    def python_binary
      @python_binary ||= begin
        `which python2`
        $?.success? ? "python" : "python" # python2 --> python by Hiyama
      end
    end
