我一直在尝试使用django和djangoitem设置scrapy蜘蛛。当我尝试运行我的蜘蛛时，item.py总是无法导入django应用程序的模型。Scrapy django模型导入错误

我建立了一个新鲜的django网站，并遵循https://stackoverflow.com/a/19073347/3988392的指示，我仍然无法从我的应用程序导入模型。我认为一切都按照该线程中的说明设置（除了我称之为testsite而不是mysite等）。但是如果有人认为它可能有用，我会发布代码。

回溯运行scrapy crawl example时：

尝试包括空'__init __。py'在'testapp'目录文件 – shaktimaan 2014-08-29 03:54:45

它看起来像有一个空的'__init __。当我跑'py'创建蟒蛇manage.py的startApp myapp'所以我不我认为那是错的。 – 2014-08-29 04:01:53

你的models.py在哪里？它在myapp文件夹或testapp文件夹下吗？ – 2014-08-29 06:59:57

我想你好想写的PYTHONPATH到Django项目。您正在添加应用程序，而不是项目。

在testbot/settings.py中添加：

# Setting up django's project full path. 
import sys 
sys.path.insert(0, '/home/TristanTrim/PycharmProjects/testsite') 

# Setting up django's settings module name. 
# This module is located at /home/rolando/projects/myweb/myweb/settings.py. 
import os 
os.environ['DJANGO_SETTINGS_MODULE'] = 'testsite.settings'

import sys 
import os

＃设置Django的项目完整路径。

sys.path.append('/home/testsite') 

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