在 virtualenv 中工作,我正在尝试安装 scikit-image,但它失败了,告诉我我需要更新(或任何)版本的 numpy。
$ sudo pip install -U scikit-image
...
ImportError: You need `numpy` version 1.6 or later.
----------------------------------------
Command python setup.py egg_info failed with error code 1 in /Users/aps/Dropbox/experiments/build/scikit-image
我不明白这一点,因为从 Python 开始,numpy 1.7 已经在我的路上了。
$ python

>>> import numpy
>>> numpy.__version__
'1.7.1'
怎么回事 - 为什么安装 scikit-image 的系统看不到最新版本的 numpy?我该如何解决这个问题?
numpy 的路径似乎已经在我的~/.bash_profile
:
>>> numpy.__path__
['/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/numpy']
>>> exit()
$ vi ~/.bash_profile
...
export PYTHONPATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages:$PYTHONPATH
更新:
numpy 1.7 版也在su
路径中:
$ sudo python
