Django新版本报错问题解决

在创建app的时候会报如下错误：

python3 manage.py startapp test

django.core.exceptions.ImproperlyConfigured: SQLite 3.9.0 or later is required (found 3.7.17).

这是因为启动app的时候会检测当前的SQLite的版本，如果低于3.9.0就会报错，如果不准备用SQLite的话，可以修改代码，如下：

vi /usr/local/python3/lib/python3.9/site-packages/django/db/backends/sqlite3/base.py

# 找到如下代码段：
def check_sqlite_version():
    if Database.sqlite_version_info < (3, 9, 0):
        raise ImproperlyConfigured(
            'SQLite 3.9.0 or later is required (found %s).' % Database.sqlite_version
        )

# 修改为：
def check_sqlite_version():
    if Database.sqlite_version_info < (3, 6, 3):
        raise ImproperlyConfigured(
            'SQLite 3.9.0 or later is required (found %s).' % Database.sqlite_version
        )
