问题解决 No module named '_sqlite3'

1、问题描述

报错信息如下：

from sqlite3.dbapi2 import *
  File "/opt/python3.6.6/lib/python3.6/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *
ModuleNotFoundError: No module named '_sqlite3'

2、解决方法

实际上这是因为缺少 /opt/python3.6.6/lib/python3.6/lib-dynload/_sqlite3.cpython-36m-x86_64-linux-gnu.so

使用下面的命令查找，发现确实没有_sqlite3.cpython-36m-x86_64-linux-gnu.so

sudo find / -name _sqlite3.cpython-36m-x86_64-linux-gnu.so

解决方法实际上很简单

(1) sudo apt install libsqlite3-dev

(2) 重新编译安装python3.6.6

首先cd进入源码根目录

sudo ./configure --prefix==/opt/python3.6.6

sudo make -j8

sudo make install
