python 导入库问题

最后的解决如下:不知道有没有多余的地方

from django.conf import settings

from sys import path
path.extend(['/home/zoueswebsite', '/home/zoueswebsite/blog', '/home/zoueswebsite/zoueswebsite'])
import os

os.environ['DJANGO_SETTINGS_MODULE'] = 'zoueswebsite.settings'


第一版本错误:

设置如下:

from django.conf import settings
settings.configure()
from sys import path
path.extend(['/home/zoueswebsite', '/home/zoueswebsite/blog', '/home/zoueswebsite/zoueswebsite'])
from blog.models import *

错误:

Traceback (most recent call last):

第一版本中:

注释掉这一行#path.extend(['/home/zoueswebsite', '/home/zoueswebsite/blog', '/home/zoueswebsite/zoueswebsite'])
会报错:


root@AY140715013539708c0eZ:~# python xmlgenerator.py
Traceback (most recent call last):
File "xmlgenerator.py", line 11, in
from blog.models import *
ImportError: No module named blog.models

第一版本中:

如果注释掉os.environ['DJANGO_SETTINGS_MODULE'] = 'zoueswebsite.settings' 但是export 包含这个设置的时候 是无变化的 但是当我unset 的时候 就会报错:

报的错误是第一个错误

第一版本中:

如果注释掉:

#from django.conf import settings

是无关紧要的

第二版本错误:

from django.conf import settings
settings.configure()
from blog.models import *

EROROR;

Traceback (most recent call last):
File "", line 1, in
ImportError: No module named blog
