在尝试从Apache服务CKAN时找不到错误

Question

我正在尝试为CKAN 2.7配置DataPusher，并且作为先决条件，我已经安装了DataStore和Apache HTTP服务器。

Apache HTTPD版本：Apache/2.4.25(UNIX(MOD_WSGI软件包安装了4.5.15conf文件的权限如CKAN文档中指定http://docs.ckan.org/en/latest/maintaining/installing/deployment.html

ckan_default.conf 的内容

WSGIScriptAlias / /etc/ckan/default/apache.wsgi
WSGIPassAuthorization On
WSGIDaemonProcess ckan_default display-name=ckan_default processes=2 threads=15
WSGIProcessGroup ckan_default
ErrorLog /var/log/apache2/ckan_default.error.log
CustomLog /var/log/apache2/ckan_default.custom.log combined

apache.wsgi文件的内容：

import os
ckan_home = os.environ.get('CKAN_HOME', '/usr/lib/ckan/default')
activate_this = os.path.join(ckan_home, 'bin/activate_this.py')
execfile(activate_this, dict(__file__=activate_this))
from paste.deploy import loadapp
config_filepath = os.path.join(os.path.dirname(os.path.abspath(__file__)), 
'production.ini')
from paste.script.util.logging_config import fileConfig
fileConfig(config_filepath)
application = loadapp('config:%s' % config_filepath)

当我启动Apache HTTPD服务器时，我在日志中看到以下错误。

任何人都可以帮我解决这个问题吗？预先感谢

ps：使用Paster Serve时，CKAN站点可以很好地加载

谢谢你格雷厄姆·邓普顿(Graham Dumpleton(。链接帮助了。问题是由于安装了Python的不同版本和虚拟环境路径。我添加并设置了适当的虚拟环境的路径。

步骤1(激活虚拟环境

步骤2(在下面执行命令以了解虚拟env

    python -c 'import sys; print(sys.prefix)'

步骤3(在ckan_default.conf文件中添加以下行(在虚拟主机之前(

    WSGIPythonHome <path you got in step 2>

步骤4(重新启动apache
