1.准备安装环境
yum groupinstall 'Development Tools'
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel
2.安装python3
去官网下载编译安装包或者直接执行以下命令下载
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
解压
tar -xvJf Python-3.6.2.tar.xz
切换进入
cd Python-3.6.2
编译安装
./configure prefix=/usr/local/python3
make && make install
安装完毕,/usr/local/目录下就会有python3了
因此我们可以添加软链到执行目录下/usr/bin
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
[root@greg02 ~]# python3
Python 3.6.2 (default, Nov 15 2017, 03:44:12)

>>> 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 *
File "/usr/local/python3/lib/python3.6/sqlite3/dbapi2.py", line 27, in <module>
from _sqlite3 import *
ModuleNotFoundError: No module named '_sqlite3'
3.安装sqlite3
官网http://www.sqlite.org/download.html
我下载的是:sqlite-autoconf-3210000.tar.gz
configure –prefix=/usr/local/sqlite3
make
make install
4.安装 sqlite-devel
yum install sqlite-devel
5.重新编译安装Python3
编辑python3.6.2里面的setup.py, 添加sqlite的搜索路径:
使用vim setup.py 打开,输入:
/sqlite_inc_paths #用于寻找该字段,如下所示:
[root@greg02 Python-3.6.2]# vim setup.py
OK
