centos6.5安装django创建app时报错

安装之前，首先已经安装好setuptools和pip。见文档

1.下载安装包，在/mnt/hdfs/sharelinux下。

 

2.#cd /mnt/hgfs/sharelinux/

#tar -zvxf Django-1.8.18.tar

#cd Django-1.8.18

#python setup.py install

最终显示成功安装

 

验证：

 

 

接下来配置：

以创建一个博客为实例：

一、创建一个工程名字为myblog

#django-admin.py startproject myblog

然后进入myblog目录，命令行下输入：

python manage.py startapp blog

这时会出现以下报错：

[root@server1 myblog]# python manage.py startapp blog

django.core.exceptions.ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named _sqlite3

 

解决方法：

由于centos6.5默认python2.6，安装django需要python版本为2.7。我自己安装python2.7后，有一些系统问题依旧依赖于python2.6版本，所以需要一些配置。

python2.7出现 import sqlite3 找不到_sqlite模块的问题。

 

1、# find / -name _sqlite*.so

 

 

2、# whereis python2.7

 

 

3、cp /usr/lib64/python2.6/lib-dynload/_sqlite3.so /usr/lib/python2.7/lib-dynload/_sqlite3.so

 

 

ok,搞定！创建app成功。
