使用django3.X版本在centos7系統運行拋錯

# [django can't find new sqlite version? (SQLite 3.8.3 or later is required (found 3.7.17))](https://stackoverflow.com/questions/55674176/django-cant-find-new-sqlite-version-sqlite-3-8-3-or-later-is-required-found)

剛剛開始拋當前版本不支持。我升級sqlite3的版本后，驗證了 sqlite3 的版本為我安裝的版本。也驗證了python3中導入的 sqlite3 版本 也是我安裝的版本。繼續運行django項目， 繼續拋以下錯誤：

以為是動態鏈接庫沒有更新 又重新安裝了一把python3.8、發現結果還是一樣不能運行成功
升級之后由一個不能被支持的參數引發NotSupportError，說明django雖然獲取到了>=3.8.3版本的sqlite，但是部分方法仍然不能支持新特性、

如此這般，只能走另外一條途徑解決問題。不依賴系統提供的sqlite3 使用 pysqlite3 和 pysqlite3-binary 庫來操作。首先需要安裝這兩個庫

pip3 install pysqlite3

pip3 install pysqlite3-binary

修改db代碼導入庫

vi /usr/local/python3/lib/python3.8/site-packages/django/db/backends/sqlite3/base.py
# 修改內容
# from sqlite3 import dbapi2 as Database (注釋掉這段)
from pysqlite3 import dbapi2 as Database # 啟用pysqlite3
# :wq 保存即可

然后可運行 python3 manage.py runserver 即成功運行
