ImportError:使用mod_wsgi时无法导入numpy.core.multiarray

Question

我在运行web.py脚本时遇到问题mod_wsgi.脚本使用numpy和opencv.

以下是我的问题的详细信息.

我在盒子上有两个python版本,但我希望脚本能够运行python2.7.所以从解释器我已经确保我可以导入cv和numpy

$ python
Python 2.7.3 (default, Oct  8 2013, 15:53:09) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> import numpy
>>> import sys
>>> sys.prefix
 '/usr/local'

我从源代码下载了mod_wsgi,并使用以下命令对其进行了配置和安装:

./configure --with-python=/usr/local/bin/python2.7 --with-apxs=/usr/sbin/apxs
LD_RUN_PATH=/usr/local/lib/ make 
sudo make install

确保正确配置mod_wsgi.

$ ldd /usr/lib64/httpd/modules/mod_wsgi.so 
    linux-vdso.so.1 =>  (0x00007fff36dff000)
    libpython2.7.so.1.0 => /usr/local/lib/libpython2.7.so.1.0 (0x00007f9462710000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f94624e8000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00007f94622e4000)
    libutil.so.1 => /lib64/libutil.so.1 (0x00007f94620e1000)
    libm.so.6 => /lib64/libm.so.6 (0x00007f9461e5c000)
    libc.so.6 => /lib64/libc.so.6 (0x00007f9461ac9000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f9462d15000)

另外,我有以下内容 httpd.conf

WSGIPythonHome /usr/local
WSGIPythonPath /usr/local/lib/python2.7/site-packages/

站点包目录包含以下文件:

cv2.so
cv.py
distribute-0.6.35-py2.7.egg
easy-install.pth
numpy-1.7.1-py2.7-linux-x86_64.egg
README
setuptools-0.6c11-py2.7.egg-info
setuptools.pth
web.py-0.37-py2.7.egg

这是脚本:

import web
import json
import cv2
#import numpy as np

urls = (
    '.*', 'Sample'
)

class Sample:
    def GET(self):
        user_data = web.input()
        return json.dumps(self.perform(user_data.color, user_data.shade))

    def perform (self,color, shade):
        return {'color': color, 'shade': shade}

application = web.application(urls, globals()).wsgifunc()

当我从浏览器访问脚本时,我看到下面的错误 error_log

[error] ImportError: numpy.core.multiarray failed to import

注意这发生import cv2在线.如果我也评论,就像import numpy as np那时我的脚本工作正常.

我确保我有以下文件:

$ sudo find / -name libpython2.7.a
/usr/local/lib/python2.7/config/libpython2.7.a
/usr/local/lib/libpython2.7.a

$ sudo find / -name libpython2.7.so*
/usr/local/lib/libpython2.7.so
/usr/local/lib/libpython2.7.so.1.0
/usr/lib/libpython2.7.so
/usr/lib/libpython2.7.so.1.0

我的python2.7配置文件显示:

config.c
config.c.in
install-sh
libpython2.7.a
libpython2.7.so -> ../../libpython2.7.so
libpython2.7.so.1.0 -> ../../libpython2.7.so.1.0
Makefile
makesetup
python.o
Setup
Setup.config
Setup.local

题

我该怎么做才能解决这个问题？

Answer 1

对于 Windows ！您需要下载并安装NumPy 1.6.1和SciPy 0.9.0（您还需要选择支持Python 2.7的文件）
