Pip 无法在Windows 64位上将ipython从1.1升级到4.0

我无法正确升级或安装ipython

上面说我需要simplegeneric，但我已经安装好了

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

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
(...)

我正在使用Python2.7，并且已经安装了MS VC++for Python

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

更新

指定版本无效，使用-U标志或不使用-U标志时相同

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

更新2

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)

---

将pip更新为新版本（从1.3.1到7.1）有帮助

---

你能添加

pip--version

和

哪个pip

？@cel我添加了pip版本。1.3是旧的吗？。到目前为止，我从未遇到过pip或easy_安装的问题，我已经使用它两年或更长时间了。
