它说我需要 simplegeneric，但我已经安装了它

这是我的 pip 冻结日志：

C:\big data\ipython-notebooks>pip freeze
(...)
ipython==1.1.0
(...)
pyzmq==14.7.0
(...)
simplegeneric==0.8.1
(...)

我使用的是 Python 2.7，并且安装了 MS VC++ for Python

C:\big data\ipython-notebooks>python --version
Python 2.7.3

更新

指定版本不起作用，无论是否使用 -U 标志都一样

C:\big data\ipython-notebooks>pip install ipython==3.2.1

Pip 版本是 1.3.1

C:\big data\ipython-notebooks>pip --version
pip 1.3.1 from c:\python27\lib\site-packages (python 2.7)

Answer 1

将 pip 更新到 新版本（从 1.3.1 到 7.1）有帮助
