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 的说明进行操作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(除了我将其称为 testsite 而不是 mysite 等)，但如果有人认为它可能有帮助，我将发布代码。

最佳答案
我认为你错过了将 pythonpath 写入你的 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'
