在服務器上剛部署完Django項目，
python manage.py runserver 0.0.0.0:8000啓動啓動的時候報錯：django.core.exceptions.ImproperlyConfigured: SQLite 3.8.3 or later is required (found 3.7.17).，以下爲報錯展示及解決辦法。
一、報錯演示

二、問題解決
-
按照習慣，翻譯一下報錯信息
![在這裏插入圖片描述]()
大致意思是：Django需要SQLite 3.8.3或更高版本，而現在的版本爲3.7.17 -
兩個解決辦法
方法一：給Django降級如果是生產環境或者項目規定了Django版本，那麼降級Django會引起一系列的問題，本人建議使用
方法二，慎重慎重，當然測試環境就無所謂了。卸載Django
pip uninstall django安裝低版本，版本號根據自身項目選擇合適的
pip install django==2.1.7方法二：升級SQLite
(1)獲取安裝包下載鏈接
下載地址：https://www.sqlite.org/download.html
![在這裏插入圖片描述]()
最好重新獲取一下下載鏈接，否則可能不是最新版（以上截圖爲本人寫此篇文章時候的最新版）
(2)wget下載
#鏈接最好重新獲取，否則可能不是最新版本 wget https://www.sqlite.org/2019/sqlite-autoconf-3300100.tar.gz(3)解壓並安裝
[root@localhost home]# tar zxvf sqlite-autoconf-3300100.tar.gz [root@localhost home]# cd sqlite-autoconf-3300100/ [root@localhost sqlite-autoconf-3300100]# ./configure [root@localhost sqlite-autoconf-3300100]# make & make install(4)查看版本
#檢查新安裝的sqlite3版本 [root@localhost home]# /usr/local/bin/sqlite3 --version 3.30.1 2019-10-10 20:19:45 18db032d058f1436ce3dea84081f4ee5a0f2259ad97301d43c426bc7f3df1b0b #檢查舊的sqlite3版本 [root@localhost home]# /usr/bin/sqlite3 --version 3.7.17 2013-05-20 00:56:22 118a3b35693b134d56ebd780123b7fd6f1497668 # 把舊的sqlite3改個名字 [root@localhost home]# mv /usr/bin/sqlite3 /usr/bin/sqlite3_old # 設置軟鏈接 [root@localhost home]# ln -s /usr/local/bin/sqlite3 /usr/bin/sqlite3 #查看sqlite3版本 [root@localhost home]# sqlite3 --version 3.30.1 2019-10-10 20:19:45 18db032d058f1436ce3dea84081f4ee5a0f2259ad97301d43c426bc7f3df1b0b(5)設置開機自啓動
# 設置開機自啓動 [root@localhost home]# export LD_LIBRARY_PATH="/usr/local/lib"(6)檢查Python的SQLite3版本
[root@localhost home]# python3 Python 3.6.5 (default, Jul 9 2019, 20:03:55) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import sqlite3 >>> sqlite3.sqlite_version '3.30.1' >>> exit() [root@localhost home]#(7)完成
如果你使用虛擬環境啓動的項目，可能還會繼續報錯，需要把虛擬環境刪除，重新創建即可
友情提示：可以先生成依賴文件，然後一會批量導入。
可能用到的命令：
- 依賴文件生成：
pip freeze > requirements.txt- 依賴文件安裝：
pip install -r requirements.txt- 創建虛擬環境(不指定Python版本，Centos7默認會使用2.7)：
virtualenv name- 創建虛擬環境(指定Python版本)：
virtualenv -p /usr/bin/python3 name
歡迎留言吐槽
