SQLite 的版本太低，和django版本不对应。

网上找了一下，有两种方法

一个是降低django的版本，不太想降级。所以就选择了第二种方法。

升级sqlite。

sqlite3 -version  了一下，还是sentOS7自带的版本 3.7.17

到sqlite的官网： https://www.sqlite.org/download.html 选择最新版的 sqlite。

顺便把下载链接搬过来了：https://www.sqlite.org/2019/sqlite-autoconf-3290000.tar.gz

下面开始敲命令：

cd ~

# 下载到服务器
wget https://www.sqlite.org/2019/sqlite-autoconf-3290000.tar.gz

# 解压安装
tar -zxvf sqlite-autoconf-3290000.tar.gz
cd  sqlite-autoconf-3290000
./configure --prefix=/usr/local
make && make install
find /usr/ -name sqlite3

 
# 替换版本
mv /usr/bin/sqlite3  /usr/bin/sqlite3_old
ln -s /usr/local/bin/sqlite3   /usr/bin/sqlite3

# 检查是否已经更新成功
sqlite3 -version

# 共享库修改，
vim /etc/profile
//打开profile文件后将下面一行代码粘贴到文本最后。记得换行，保存退出
export LD_LIBRARY_PATH="/usr/local/lib"

# 配置生效
source /etc/profile

 

# 检查Python的sqlite3 的版本
python3
>>>import sqlite3
>>>sqlite3.sqlite_version

# 打印最新的版本号就表示ok了

再次运行 python manage.py createapp myapp 就可以正常createapp了
