IRubyはじめました

表題のとおり、 IRuby をはじめてみました

インストール

インストールは簡単で gem install iruby でいけますが、私の利用している環境では依存している czmq が古かったので手動でインストールして回避しています。

git clone https://github.com/zeromq/czmq.git
cd czmq
./autogen
./configure --prefix=${HOME}/.local
make -j4
make install
gem install iruby cztop
LD_LIBRARY_PATH=${HOME}/.local/lib iruby

でインストールと動作はできます。画像貼るのがメンドイので ipython 貼っておきます。
