ImportError: IPython.html requires pyzmq >= 2.1.11

requires pyzmq >= 2.1.11

とありますが、pyzmqはインストール済みです。
実際

pip install pyzmq

とすると

Requirement already satisfied (use --upgrade to upgrade): pyzmq in ./.pyenv/versions/3.4.0/lib/python3.4/site-packages
Cleaning up...

と出てきます。
恐らくpyenvを入れているせいで、認識されていないと思うのですが、解決策がわかりません。

よろしくお願いいたします。
