Cygwinにipythonを入れてみた

TAB補完などが可能ということで、対話実行型のシェルであるipythonを入れてみた。

pyreadlineが必要とのことで、easy_installでインストール

If you suspect this is an IPython bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at ipython-dev@scipy.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
    c.Application.verbose_crash=True

パッケージの依存関係がおかしくなったのか、とりあえずpyreadlineをいったん削除

$easy_install -mxN pyreadline

Removing pyreadline 2.0 from easy-install.pth file

Using /usr/lib/python2.7/site-packages/pyreadline-2.0-py2.7.egg

Because this distribution was installed --multi-version, before you can
import modules from this package in an application, you will need to
'import pkg_resources' and then use a 'require()' call similar to one of
these examples, in order to select the desired version:

    pkg_resources.require("pyreadline")  # latest installed version
    pkg_resources.require("pyreadline==2.0")  # this exact version
    pkg_resources.require("pyreadline>=2.0")  # this version or higher

pipでpyreadlineを再インストールしようとしたら、pipも何故かエラーorz
Permission denied? root権限なんだけど..ﾇｰﾝ

$pip

pipを再インストール

無事起動ｼﾀ!

$pip --version

再度pyreadlineをインストール

$pip install pyreadline

なんかすでにある的なことを言われたので、-mでもう一回削除したけどダメ
pipでuninstallを試みる

$pip uninstall pyreadline

エラーでたけど..上手くいったのかな?

そしてipythonを起動
