当在虚拟环境下和内部导入时，Pandas 正在生成“模块”对象没有属性“核心” 。它可以在虚拟环境内的开发服务器下正常运行。djangomod_wsgidjango

其他模块，例如：numpy 没有问题，所以我认为这意味着虚拟环境已正确设置mod_wsgi。任何意见，将不胜感激。

分期.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

Traceback (most recent call last):

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

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，这会导致问题。

'RuntimeError: module compiled against API version 6 but this version of numpy is 4'是我在原始帖子中遗漏的错误行，它可能有助于调试答案。
