在Ubuntu系統中啓動Django項目報錯：ModuleNotFoundError: No module named '_sqlite3’
1.首先安裝缺失的sqlite3庫：
sudo apt-get install sqlite-devel
或
sudo apt-get install libsqlite3-dev
2.如果上面的方法不行，重新下載編譯安裝sqlite3
sudo wget https://www.sqlite.org/2018/sqlite-autoconf-3250300.tar.gz
sudo tar zxvf sqlite-autoconf-3250300.tar.gz
cd sqlite-autoconf-3250300
sudo ./configure
sudo make && make install
3.安裝結束後，進入到python源文件目錄下，重新編譯安裝python即可
sudo ./configure
sudo make && make install
4.進入到django項目下啓動項目：
python3 manage.py runserver
項目順利運行:
root@ubuntu:/home/fanzhh/projects/mysite# python3 manage.py runserver
