推荐答案
经过大量的跟踪、错误和谷歌搜索，我终于能够成功运行.
After lots of trail and error and googling, finally i was able to run successfully.
我收到了 lru_cache 错误，因为我执行了 sudo apt-get install libapache2-mod-wsgi安装 mod-wsgi.我认为这可能已安装到 Ubuntu 16.04(即 python2.7)上的默认 python.
I got the lru_cache error because, I did sudo apt-get install libapache2-mod-wsgi to install mod-wsgi. I think this might have installed to default python on Ubuntu 16.04 which is python2.7.
解决方案:我从ubuntu卸载libapache2-mod-wsgi并用pip install mod-wsgi安装，最后从site-packages目录复制安装mod-wsgi的路径并在里面更新apache2/mods-available/wsgi.load 文件.
Solution: I uninstalled libapache2-mod-wsgi from ubuntu and installed it with pip install mod-wsgi and then finally copied the path of installed mod-wsgi from site-packages directory and updated it inside apache2/mods-available/wsgi.load file.
所以最好从 virtualenv 或普通 python3 安装 mod-wsgi，然后更新 apache 文件，而不是直接在 ubuntu 上安装 libapache2-mod-wsgi.
So its better to install mod-wsgi from virtualenv or normal python3 and then update apache files instead of installing libapache2-mod-wsgi directly on ubuntu.
