Django 1.7 makemigrations 冻结/挂起

2024-04-29

我终于从 Django 1.6 升级到 1.7，并在此过程中删除了 South。我跟着Django 官方说明 https://docs.djangoproject.com/en/1.7/topics/migrations/#upgrading-from-south并删除了我所有旧编号的迁移。现在我正在尝试跑步python manage.py makemigrations让新的迁移继续使用 1.7 的迁移模块，但它完全挂起，我得到的唯一输出如下：

bash -cl "/Users/me/.virtualenvs/mysite-Dj17/bin/python /Applications/PyCharm.app/Contents/helpers/pycharm/django_manage.py makemigrations /Users/me/Coding/mysite"
/Users/me/.virtualenvs/mysite-Dj17/lib/python2.7/site-packages/django/test/_doctest.py:59: RemovedInDjango18Warning: The django.test._doctest module is deprecated; use the doctest module from the Python standard library instead.
  RemovedInDjango18Warning)

/Users/me/.virtualenvs/mysite-Dj17/lib/python2.7/site-packages/django/test/simple.py:27: RemovedInDjango18Warning: The django.test.simple module and DjangoTestSuiteRunner are deprecated; use django.test.runner.DiscoverRunner instead.
  RemovedInDjango18Warning)

然后，即使我将其放置几个小时，也不会发生任何事情。

这里发生了什么？如何调试manage.py命令？

Update:

运行后dtruss per @威尔弗雷德休斯根据建议，我得到以下输出（顶部的输出已被剪裁，因为对于 StackOverflow 来说太长）：

sudo dtruss python manage.py makemigrations

Update:根据下面的评论和答案，我尝试完全关闭并重新启动 Postgres 以确保没有打开的连接，并且makemigrations仍然挂起。然而，我did请注意，如果我让 Postgres 完全关闭（通过尝试确认）$ psql并没有得到回应），然后尝试makemigrations，我也有同样的行为。


您应该尝试禁用所有已安装的应用程序，看看是否可以解决问题。如果确实如此，请隔离导致问题的原因。然后设置调试跟踪。
