測試伺服器執行報錯，這是由於centos7系統自帶的sqlite版本比較低，有多種辦法可以解決這個報錯

django.core.exceptions.ImproperlyConfigured: SQLite 3.8.3 or later is required (found 3.7.17).
法一：註釋掉預設的sqlite資料庫，改用mysql或postgresql
# vim settings.py
#DATABASES = {
# 'default': {
# 'ENGINE': 'django.db.backends.sqlite3',
# 'NAME': BASE_DIR / 'db.sqlite3',
# }
#}
法二：升級系統自帶的sqlite3版本
sqlite官網下載：https://www.sqlite.org/download.html
選擇sqlite-autoconf這個，帶configure指令碼方便編譯
解壓&編譯&安裝
tar zxvf sqlite-autoconf-3340000.tar.gz
cd sqlite-autoconf-3340000
./configure
make && make install確認版本
# /usr/local/bin/sqlite3 --version
3.34.0 2020-12-01 16:14:00 a26b6597e3ae272231b96f9982c3bcc17ddec2f2b6eb4df06a224b91089fed5b
移除老的sqlite3版本，不要直接解除安裝，centos有很多包依賴這個，直接yum remove sqlite會導致系統有問題
# mv /usr/bin/sqlite3 /usr/bin/sqlite3_ori設定連結庫
# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/lib # 這個是追加的，sqlite編譯把lib庫檔案都放在這個路徑下的
# ldconfig 再執行下這個命令，在當前執行時中生效
確認python的sqlite版本
>>> import sqlite3
>>> sqlite3.sqlite_version
'3.34.0'
再次執行django測試服務，就不會再報錯了
# python manage.py runserver
