熊猫+ Django + mod_wsgi + virtualenv

Question

熊猫正在制作＆＃39;模块＆＃39;在虚拟环境中的django和mod_wsgi下导入时，对象没有属性＆＃39; 。它在虚拟环境中的django开发服务器下运行良好。

其他模块例如：numpy没有问题因此我认为这意味着使用mod_wsgi正确设置了虚拟环境。任何建议将不胜感激。

staging.wsgi

import os
import sys
import site

PROJECT_ROOT = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))
site_packages = os.path.join(PROJECT_ROOT, 'env/openportfolio/lib/python2.7/site-packages')
site.addsitedir(os.path.abspath(site_packages))
sys.path.insert(0, PROJECT_ROOT)
sys.path.insert(0, os.path.dirname(os.path.dirname(__file__)))
os.environ['DJANGO_SETTINGS_MODULE'] = 'openportfolio.settings_staging'

import pandas #triggers error
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

错误

Answer 1

事实证明这是一个Python路径顺序问题。通过在我的wsgi配置文件中运行sys.path.reverse（），代码现在可以运行了。

由于Python路径的顺序，必须首先在虚拟环境中导入内置的OS X numpy库，导致问题。

'RuntimeError：针对API版本6编译的模块，但此版本的numpy为4'是我在原始帖子中遗漏的错误行，可能有助于调试答案。
