Question

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

> 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时安装的，但pip freeze显示有关SVN位置的警告

> pip freeze
Warning: cannot find svn location for pyreadline==1.7.1.dev-r0
...
ipython==0.13.1
## FIXME: could not find svn URL in dependency_links for this package:
pyreadline==1.7.1.dev-r0
...

Answer 1

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

ipython不会在Windows上运行
