在WSGI模式下在Apache中接收“无模块命名编码错误”

Question

我遇到了“没有名为‘编码’的模块”错误。在我看来，Python虚拟环境没有正确加载。但是我还包含了wsgi文件以防万一。

httpd使用模块/wsgi.solddwsgi.so：

• 创建一个新用户“python\u user:python\u user”（uid=501）
• 创建一个目录/var/www/m.abcd。com并由python_用户拥有：python_用户。此外，子目录也归python\u用户所有：python\u用户
• 在/var/www/m.abcd下。com，创建python src、venv、html、logs、applogs等
• python src包含安装程序。py和应用程序源文件
• 通过运行python3-m venv venv（编辑：非python2）（设置虚拟环境）来设置venv
• 在python src中，pip安装-e 将应用程序依赖项添加到虚拟环境

下面是我在格雷厄姆·邓普尔顿的帮助下在评论部分找到的。

问题是来自AmazonLinux的mod_wsgi的默认安装非常旧的3.5。使用pip-3.6安装mod_wsgi（当前为4.6.2）并将其链接到httpd后，问题得到解决。
