Django和apache2（没有virtualenv）：ImportError：没有名为“Django”的模块

Question

我试图通过一个小型的Django站点从一个服务器移植到另一个服务器。在新服务器上，我安装了以下组件：

Ubuntu 16.04.3 LTS
Python 3.5.2
apache 2.4.18
mod_wsgi 4.5.17 (built from source with Python 3.5)
django 1.11.4 (installed using pip3 **without** a virtualenv)

在apache2.conf文件的底部，我添加了以下几行

^{pr2}$

其中/home/user/ProductionServer是我的django站点的根目录。在

站点内启用/000-默认.conf，我有以下内容：

<VirtualHost *:2799>
        ServerName myserver.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        WSGIScriptAlias / /home/user/ProductionServer/my_app/wsgi.py

        Alias /static /home/user/ProductionServer/static

        <Directory /home/user/ProductionServer/my_app>
                <Files wsgi.py>
                        Require all granted
                </Files>
        </Directory>
        <Directory /home/user/ProductionServer/static>
                Require all granted
        </Directory>
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

我可以使用管理.pyrunserver命令。但是，当我通过apache运行它时，在apache2.error文件中收到以下错误消息：

我的文件夹结构如下：

ProductionServer
├── another_app
│   ├── ....
├── manage.py
├── my_app
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── static
    └── ...

有什么想法吗？在

Answer 1

问题是，尽管我最初是这么想的，但pip只为我的本地用户安装了django。为了在全局范围内安装django，我必须使用-H选项运行pip：

sudo -H pip3 install django
