Django 1.7 makemigrations freezing/hanging

问题

I'm finally upgrading from Django 1.6 to 1.7, and removing South in the process. I followed the official Django instructions and removed all my old numbered migrations. Now I'm trying to run python manage.py makemigrations to get the new migrations to continue moving forward with 1.7's migrations module, but it completely hangs and the only output I get is the following:

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)

And then even if I leave it for hours, nothing happens.

What is happening here? How can I debug a manage.py command?

Update:

After running with dtruss per @WilfredHughes's advice, I get the following output (output at the top has been clipped because was too long for StackOverflow):

sudo dtruss python manage.py makemigrations

Update: Per comments and answers below, I tried completely shutting down and restarting Postgres to ensure that there were no open connections, and makemigrations still hangs. However, what I did notice is that if I kept Postgres completely shut down (confirmed by trying $ psql and getting no response), and then trying makemigrations, I had the same behavior.

回答1:

You should try disabling all of your installed_apps and seeing if that solves the problem. If it does, isolate the one causing the issues. Then set debugging traces.

回答2:

Django 1.7 had this bug apparently that can cause migrations for a large enough number of models to freak out. They said they were doing something about this, and seems like they might have fixed it in 1.7.1.

https://docs.djangoproject.com/en/1.7/releases/1.7.1/

It's the third entry, and there's a few more improvements that may be connected to this.

Heard it first in this talk, hope it solves your problem: https://www.youtube.com/watch?v=bjIXZ-XX2SM

回答3:

Are there open connections to the database you're migrating? If so, that is probably the reason your migration hangs. See this south bug for more information. I realise that Django 1.7 does not use south and that bug refers specifically to south. Migrations are built directly in Django 1.7, but since other people have the same problem, I fear this issue is still around.

回答4:

I had exactly the same issue, and as suggested in another answer i tried to eliminate applications in INSTALLED_APPS and then found my app which was causing this behavior.

Finally this line of code was the cause:

import fabric

when i removed it everything worked fine.

回答5:

I noticed (following first django tutorial) that adding new field to the model class causes makemigrations to hang. Editing existing field, removing field, adding new model class - it all works, only adding new field to existing class hangs. Im not sure if this is also the case in 1.8 version.

Edit: this only happens in git bash under windows 7. when I try windows cmd console - it works.
