Django报错：ImportError: No module named 'pysqlite2'

发表于 | 分类于 ，

运行环境：Cent OS6.5，Python3.4.3，Django1.8.3

执行如下命令时报错： 

python manage.py runserver

错误信息如下：

django.core.exceptions.ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named 'dbapi2'

解决：
1.安装sqlite-devel 

yum install sqlite-devel

此时又出现错误信息： 

  File "/usr/bin/yum", line 30
    except KeyboardInterrupt, e:
                            ^
SyntaxError: invalid syntax

由于python3和python2语法规则不同导致，修改/usr/bin/yum第一行： 

#!/usr/bin/python_old

然后就可以安装sqlite-devel了。

2.重新编译安装python： 

./configure --prefix=/usr/local/python-3.4.3
make
make install

再次运行django，问题解决。
