我的目录结构可以从这张大图片中看到：directory tree

1 个答案:

答案 0 :(得分：0)

在屏幕快照中很难看到它，但是看起来直接的问题是您拥有额外的目录级别：

  • .git/
  • fixandflex/←
    • fixandflex/
      • settings.py
      • wsgi.py
      • ...
    • main/
      • ...
  • Pipfile
  • Pipfile.lock
  • ...

通常，顶级fixandflex/目录中的所有内容都将位于存储库的根目录中，位于.git/，Pipfile和Pipfile.lock旁边。

您可以从顶级项目目录中执行以下操作：

mv fixandflex fixandflex-old
cd fixandflex-old
git mv fixandflex ..
cd ..
rmdir fixandflex

然后提交并部署。

如果您不想这样做，则可以通过修改Procfile使其与现有目录结构一起使用：

web: gunicorn fixandflex.fixandflex.wsgi

尽管这样做，您将遇到其他问题。例如，您将必须更新DJANGO_SETTINGS_MODULE并将另一个fixandflex.放在前面。而且，您可能必须对设置文件中的任何INSTALLED_APPS执行相同的操作。总而言之，我建议删除无关的目录。

除了该问题之外，您还有一个名为requirement.txt的文件，该文件（a）的命名方式不是常规名称（通常是requirements.txt，结尾是s），（b）则不是如果您有Pipfile和Pipfile.lock，则必须由Heroku使用或使用。我建议删除它。

此外，我还看到一个db.sqlite3文件。如果您使用的是SQLite，则应该知道，由于其ephemeral filesystem和should not be used on Heroku，这在Heroku上无法正常工作。

我强烈建议使用相同的数据库引擎进行本地开发和生产。它们都是微妙的（并且不是那么微妙）不同，并且您不想只在代码投入生产后才发现错误。 PostgreSQL是常见的选择，并且在Heroku上得到了很好的支持，例如使用Heroku's own Postgres service。
