django - heroku 没有名为 _sqlite3 的模块

Question

尝试在 heroku 上部署 django 应用程序时，出现以下错误。我可以在本地测试。它工作正常。但是“heroku run python manage.py syncdb”会导致以下错误。我浏览了其他一些相关的帖子，但找不到满意的答案。

我有 python 2.7 和 django 1.3 并使用 sqlite3 作为数据库。我正在尝试在 heroku 上部署以下内容 - https://github.com/Stackato-Apps/pinax-social .如果您需要更多信息，请告诉我。

Heroku 不支持 SQLite3，您应该按照此处 https://devcenter.heroku.com/articles/django#database-settings 的描述使用 Postgres 配置您的应用程序
