django makemigrations 与 python-social-auth 导致权限被拒绝错误

Question

将 python 社交身份验证添加到我安装的应用程序后，即

INSTALLED_APPS = (
    ...
    'social.apps.django_app.default',
    ...
)

然后尝试

python manage.py makemigrations

我收到一个毫不奇怪的权限错误

Migrations for 'default':
  0002_auto_20150217_2053.py:
    - Alter field user on usersocialauth
Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/lib/python2.7/site-packages/django/core/management  /__init__.py", line 385, in execute_from_command_line
utility.execute()

  output = self.handle(*args, **options)

  self.write_migration_files(changes)

  with open(writer.path, "wb") as fh:
  IOError: [Errno 13] Permission denied: u'/usr/lib/python2.7/site-packages/social/apps/django_app/default/migrations/0002_auto_20150217_2053.py'

我无法写入系统范围的包安装目录，这是有道理的。

有一些明显的方法可以解决这个问题，例如更改 site-packages/social 目录的权限。然而，这是唯一的方法吗，还是我错过了什么？

通过上面接受的解决方案，您可以有效地将项目文件放入您的 python 环境中。每次部署到新服务器时，您都必须运行 makemigrations 来创建这些文件。

如何告诉 makemigrations 将社交迁移放入您自己的项目中？

MIGRATION_MODULES = {
    # social.apps.django_app.default    
    'default': 'myproject.mysocial.migrations',           
}

这样，当您部署到服务器时，您的项目是独立的，并且无需破坏您的 Python 环境即可运行。
