wsgi无法从其他位置加载应用程序

Question

当我从某个位置直接加载我的课程时，我可以加载它。

>>> import sys
>>> sys.path.append('/path/to/my/flask/application')
>>> from myfile import app as application
>>> 

现在来自wsgi，当我做同样的事情时......它没有加载。

下面的wsgi虚拟主机配置：

WSGIPythonHome /pathto/condadir
WSGIPythonPath /pathto/condadir/lib/python2.7
<virtualhost *:80>
    ServerName myhost.example.com

    WSGIDaemonProcess webtool user=apache group=root threads=5 home=/var/www/flask-prod/
    WSGIScriptAlias / /var/www/flask-prod/webtool.wsgi

    <directory /var/www/flask-prod>
        WSGIApplicationGroup %{GLOBAL}
        WSGIScriptReloading On
        Order allow,deny
        Allow from all
    </directory>
</virtualhost>

以下是wsgi文件。

#!/pathto/condadir/bin/python

import sys
sys.path.append('/path/to/my/flask/application')
from myfile import app as application

服务器挂载状态：

$ df -hP
