当我尝试运行IPython
时，我收到此错误消息Traceback (most recent call last):
File "/usr/local/bin/ipython", line 5, in <module>
from IPython import start_ipython
ImportError: cannot import name start_ipython
所以我决定这样做：
sudo pip uninstall ipython
sudo pip install ipython
我无法重新安装，我收到此错误消息：
Requirement already satisfied (use --upgrade to upgrade): ipython in /usr/local/lib/python2.7/site-packages
Cleaning up...
我正在运行Mac OS X 10.9
