ipython不會在Windows上運行

Question

通過pip install ipython ipython在Windows上pip install ipython ，我無法運行它並收到以下錯誤。

> 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

當ipython通過pip時安裝pyreadline，但是pip freeze顯示有關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

解決方法是卸載安裝ipython時拉出的pyreadline版本（ pip uninstall pyreadline ）並從http://www.lfd.uci.edu/下載並安裝pyreadline-1.7.1.win32-py2.7.‌exe 。 gohlke / pythonlibs /＃pyreadline
