Question

请帮助提供任何将wsgi或apache定向到正确的sqlite3库的想法。

我试图在CentOS Web服务器上部署一个具有基本模块和“ hello world”首页的网站。但是，引发了内部服务器错误，仅在www.example.com上的Web冲浪（端口80）中发生。调用“ python3 manage.py runserver”（Django版本：2.2.2）时，（端口8000）运行良好。上面是错误的详细信息，这是关于需要使用错误版本的SQLite 3.8.3或更高版本（发现3.7.17）的原因。

我曾经重新安装sqlite3，但无法正常工作。将base.py的内容更改为以下命令时，可以在管理页面出现故障时访问hello world站点（可能是由于另一个问题...）。但是硬编码并不健康...

if Database.sqlite_version_info < (3, 7, 3):

无论在根环境和虚拟环境中，python2和python3都可以打开3.28.0版的sqlite3

Answer 1

这是Ubuntu / Debian依赖项的问题，当前稳定版本中的python构建与Django 2.2的sqlite要求不兼容。有两种解决方案：

简单的方法就是将Django降级到OS软件包可以满足要求的2.1.2
使用必需的sqlite依赖项编译Python3。

[Django]显示错误配置的错误“需要SQLite 3.8.3或更高版本（找到3.7.17）”，但在manage.py runserver中正常工作
