ipython不能在Windows上运行

Question

通过pip install ipython在Windows上安装ipython之后，我无法运行它并收到以下错误。在

> ipython
Traceback (most recent call last):
  File "C:\Python27\scripts\ipython-script.py", line 5, in <module>
    from pkg_resources import load_entry_point
  File "C:\Python27\lib\site-packages\pkg_resources.py", line 2607, in <module>
    parse_requirements(__requires__), Environment()
  File "C:\Python27\lib\site-packages\pkg_resources.py", line 565, in resolve
    raise DistributionNotFound(req)  # XXX put more info here
pkg_resources.DistributionNotFound: pyreadline>=1.7.1

pyreadline是在ipython通过pip安装的，但是pip freeze显示有关SVN位置的警告

解决方案是卸载安装ipython时拉出的pyreadline版本（pip uninstall pyreadline），然后从http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyreadline下载并安装pyreadline-1.7.1.win32-py2.7.‌exe
