我一直在尝试使用 django 和 djangoitem 设置一个 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。

我建立了一个新的 django 站点并按照 https://stackoverflow.com/a/19073347/3988392 中的说明进行操作而且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所述进行设置(除了我将事物称为 testsite 而不是 mysite 等。)但是如果有人认为它可能有帮助，我会发布代码。

运行scrapy crawl example时的回溯:

请您参考如下方法:

我想你错过了将 pythonpath 写入你的 django 项目。您添加的是应用程序，而不是项目。

在 testbot/settings.py 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'
