一、背景
1、Python版本：Python 3.6.8
2、Django版本：3,.1.3
3、报错信息
File "/usr/local/lib/python3.6/site-packages/django/db/backends/sqlite3/base.py", line 70, in <module>
check_sqlite_version()
File "/usr/local/lib/python3.6/site-packages/django/db/backends/sqlite3/base.py", line 67, in check_sqlite_version
raise ImproperlyConfigured('SQLite 3.8.3 or later is required (found %s).' % Database.sqlite_version)
django.core.exceptions.ImproperlyConfigured: SQLite 3.8.3 or later is required (found 3.7.17).
二、解决方法
1、降级Django版本到django==2.1.7
但这种方法不推荐，依赖太多
2、升级sqlite
（1）安装包下载地址：https://sqlite.org/download.html
（2）下载最新压缩包
wget https://www.sqlite.org/2022/sqlite-autoconf-3390300.tar.gz
（3）解压安装
#解压缩
tar zxvf sqlite-autoconf-3390300.tar.gz
#安装
cd sqlite-autoconf-3390300/
./configure
make & make install
（4）更新版本
# 把旧的sqlite3改个名字
mv /usr/bin/sqlite3 /usr/bin/sqlite3_old
# 设置软链接
ln -s /usr/local/bin/sqlite3 /usr/bin/sqlite3
#查看sqlite3版本
sqlite3 --version
（5）确认版本
#更新前
[root@test-qa-app-01 home]# python3
