报错原因：

Django的版本太高，sqlite的版本太低。

 

解决办法：

方法1：给Django降级

方法2：给sqlite升级

 

 

sqlite升级方式：

（1）下载sqlite安装包

 

（2）上传安装包到服务器上

（3）解压

（4）进入解压后的sqlite目录

（5）编译安装

?

./configure --prefix=/usr/local/sqlite　　   make && make install

　　

（6）移除旧的sqlite版本

?

1	mv /usr/bin/sqlite3 /usr/bin/sqlite3_old_version

　　

（7）给新的sqlite添加软链接

?

1	ln -s /usr/local/sqlite/bin/sqlite3 /usr/bin/sqlite3

　　

（8）修改共享库

?

vim /etc/profile   export LD_LIBRARY_PATH="/usr/local/sqlite/lib"

　　

（9）生效并检查sqlite版本

?
