OS X Mavericksにpyreadlineがうまく入らない(けどよく考えたら必要なかった)話

python3でiPyhtonをインストールしようとした時に、適当にググって「windowsだとpyreadlineがいるのか、とりあえずmacでも入れよう」と思いインストールし、iPythonを入れたら起動時にエラーが出ました。

Traceback (most recent call last):

pyreadlineのエラーっぽかったので再インストールしてみたら、

$pip3 install pyreadline
Downloading/unpacking pyreadline
  Downloading pyreadline-2.0.zip (108kB): 108kB downloaded
  Running setup.py egg_info for package pyreadline
    
    package init file 'pyreadline/configuration/__init__.py' not found (or not a regular file)
Installing collected packages: pyreadline
  Running setup.py install for pyreadline
    package init file 'pyreadline/configuration/__init__.py' not found (or not a regular file)

Successfully installed pyreadline

って感じのエラーが出てました。

__init__.pyが見つかってないのにインストール成功ってでて、それが原因でiPythonの起動エラーが起きてる...?

対処のしようがなかったので、pyreadlineをアンインストールしてiPython起動してみたらちゃんと起動しました。
