Apache + mod_wsgi - Python 不加载已安装的模块

Question

我有一个带有 mod_wsgi 的 Apache 服务器，运行 Python 2.7 脚本。该脚本使用通过 pip 安装的 python Pillow 模块。

使用正常运行脚本可以正常python script.py工作，但是当从 wsgi 运行脚本时 - 会为 PIL 引发 ImportError 异常。

这是来自 Apache 的配置/etc/apache2/sites-enabled/000-default.conf：

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/

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

        WSGIScriptAlias /wsgi/ /home/nitay/Desktop/WebsitePath/Python/wsgi.py

        <Directory "/home/nitay/Desktop/WebsitePath/Python">
            Require all granted
        </Directory>
</VirtualHost>

没有安装virtualenv，这台机器上只有一个Python安装。

我该怎么做才能让 python 找到它安装的模块？

我已经看到了使用 mod_wsgi 的守护进程模式手动定义 python 路径的同一个球场的解决方案。有没有办法在嵌入式模式下这样做？

编辑：Apache 错误日志：

正常 Python 和 WSGI 的 sys.path 和版本：

Normal:
>>> sys.version
'2.7.11+ (default, Apr 17 2016, 14:00:29) \n[GCC 5.3.1 20160413]'
>>> sys.path
['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/home/nitay/.local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/gtk-2.0']

就我而言，模块安装在用户环境中，而不是机器的环境中。我只是运行：

sudo -H pip3.7 install mako

该-H说要sudo安装该模块中的根目录机器VS谁运行命令的用户目录...

这是因为 Apache 无法访问/读取个人用户的文件。
