>>> import sqlite3
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/python3/lib/python3.6/sqlite3/__init__.py", line 23, in <module>
from sqlite3.dbapi2 import *

ModuleNotFoundError: No module named '_sqlite3'

1、安装sqlite3

先执行

sqlite3 -version

输出下面的版本信息说明已经安装了sqlite3，那直接跳过1.1，进行1.2操作

[root@ns Python-3.7.0]# sqlite3 -version
3.7.17 2013-05-20 00:56:22 118a3b35693b134d56ebd780123b7fd6f1497668

1.1、安装sqlite3

wget https://www.sqlite.org/2021/sqlite-autoconf-3350500.tar.gz
configure –prefix=/usr/local/sqlite3
make
make install

1.2、安装 sqlite-devel

yum install sqlite-devel

2、配置安装python

编辑python3.7目录里面的setup.py,添加sqlite的搜索路径:

vim setup.py
/*直接输入下面的字符,就能跳转到所属行，python 3.7.0大概在1130行，不会vim的去百度一下啊
键盘/搜索字符
键盘i输入字符
键盘:wq保存文件并退出
键盘:q!强制退出，不保存文件
键盘esc取消命令
*/
/sqlite_inc_paths
改为以下内容，增加了后3行
        sqlite_inc_paths = [ '/usr/include',
                             '/usr/include/sqlite',
                             '/usr/include/sqlite3',
                             '/usr/local/include',
                             '/usr/local/include/sqlite',
                             '/usr/local/include/sqlite3',
                             '/usr/local/sqlite3/include',
                             '/usr/local/sqlite3/include/sqlite',
                             '/usr/local/sqlite3/include/sqlite3',
                             ]

3、重新安装python3.7

下面的代码是带SSL安装的，安装方法见上一篇文章
CentOS7 Python3.7 pip安装找不到TLS/SSL处理方式

LD_RUN_PATH=/usr/local/lib ./configure LDFLAGS="-L/usr/local/lib" CPPFLAGS="-I/usr/local/include" --with-openssl=/usr/local/openssl
LD_RUN_PATH=/usr/local/lib make
make install

3、安装完成

[root@ns Python-3.7.0]# sqlite3 -version
3.7.17 2013-05-20 00:56:22 118a3b35693b134d56ebd780123b7fd6f1497668
[root@ns Python-3.7.0]# vim setup.py
[root@ns Python-3.7.0]# /usr/local/bin/python3.7
