Question

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

然后我尝试在Python中调用numpy，但得到一个错误：

ImportError: cannot import name datetime_data.

为什么会这样？附加完整的错误消息。

Answer 1

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

然后您使用apt-get安装的numpy应按预期工作。

升级我的numpy版本后，我遇到了类似的问题。我解决了它重新安装和删除numpy lib文件夹（对于你的python版本）

sudo apt-get remove python-numpy
sudo rm -r /usr/local/lib/pythonX.X/dist-packages/numpy
sudo apt-get install python-numpy

（或从任何numpy包中安装新的numpy版本）
