centos7安装python3和Django后，ModuleNotFoundError: No module named '_sqlite3'，python3django,1.准备安装环境yu

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

cdPython-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

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/sqlite3make 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：

[[email protected] Python-3.6.2]# vim setup.py

OK
