根据Scipy网站的说法,在Ubuntu 11.10中,numpy和scipy预先打包,所以我做的是：
apt-get install python2.7 apt-get install python-numpy apt-get install python-scipy
ImportError: cannot import name datetime_data.
任何想法为什么会这样？附加完整的错误消息.

看起来你在/usr/local/lib/python2.7/dist-packages中有一个破坏的numpy安装,包管理器将numpy安装到/usr/lib/pyshared/python2.7
你应该删除破碎的numpy
$sudo rm -rf /usr/local/lib/python2.7/dist-packages/numpy
那么你用apt-get安装的numpy应该按预期工作.
