我正在尝试在运行git push heroku master之后在Heroku上部署我的Django应用程序，然后heroku open因异常而失败。
heroku logs显示：

我无法弄清楚是什么导致了这个错误，请有人指导我这个。
答案 0 :(得分：0)
ImportError: No module named taggit：Python进程无法找到taggit模块。我假设你使用的是django-taggit：https://pypi.python.org/pypi/django-taggit。
通常，Heroku接受requirements.txt作为依赖项列表。在文件中添加一行django-taggit~=0.22.2，提交它，然后推送到Heroku。
