安装Anaconda2.4.0后无法导入scipy

Question

我试图在Windows上导入Python 2.7.10中的numpy和scipy

我无法通过pip或在以下位置提供的二进制文件安装scipy:

http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy

但我听说Anaconda的标准是numpy和scipy.值得注意的是我可以成功导入numpy.

conda list

打印出所有包,scipy就是其中之一,但导入仍然失败.

我跑的时候

$ conda install scipy

这就是我所看到的:

$ conda install scipy
Fetching package metadata: ....
Solving package specifications: ..................
Package plan for installation in environment c:\Users\Nick\Anaconda2:

The following NEW packages will be INSTALLED:

conda-env: 2.4.4-py27_1

Proceed ([y]/n)? y

Linking packages ...
"Ensuring that c:\Users\Nick\Anaconda2\Library\bin is on user PATH environment variable."
"" was unexpected at this time.
Error: Error: post-link failed for: conda-env-2.4.4-py27_1

我跑的时候

$ conda install -f scipy

这就是我所看到的:

$ conda install -f scipy
Fetching package metadata: ....
Solving package specifications: ..................
Package plan for installation in environment c:\Users\Nick\Anaconda2:

The following packages will be UPDATED:

scipy: 0.16.0-np110py27_0 --> 0.16.0-np110py27_0

Proceed ([y]/n)? y

它似乎工作,但当我尝试在我的Python程序的顶部导入scipy时,我得到:

$ python steps.py
Traceback (most recent call last):
  File "steps.py", line 16, in <module>
    import scipy as st
ImportError: No module named scipy 

我做错了导入吗？

根据我的研究，尤其是github.com/conda/conda/issues/1786，我相信 Anaconda 2.4.0 对于 scipy 失败。解决方案是获取更新版本的 Anaconda 或考虑安装最新的 Miniconda。
