【问题描述】：

尝试在 heroku 上部署 django 应用程序时，我收到以下错误。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。

【问题讨论】：

嗯，这些包似乎丢失了，或者它们从你的 python 路径中丢失了

你不能在 Heroku 上使用 sqlite3。您需要使用 postgres。

【参考方案1】：

Heroku 不支持 SQLite3，您应该使用 Postgres 配置您的应用程序，如下所述https://devcenter.heroku.com/articles/django#database-settings
