execute_managerdeprecated in Django 1.4 as part of the project layout refactor and was removed in 1.6 per the deprecation timeline: https://docs.djangoproject.com/en/1.4/internals/deprecation/#id3
execute_manager作为项目布局重构的一部分，在 Django 1.4 中已弃用，并在 1.6 中根据弃用时间表删除：https: //docs.djangoproject.com/en/1.4/internals/deprecation/#id3
To fix this error you should either install a compatible version of Django for the project or update the manage.pyto new style which does not use execute_manager: https://docs.djangoproject.com/en/stable/releases/1.4/#updated-default-project-layout-and-manage-pyMost likely if your manage.pyis not compatible with 1.6 then neither is the rest of the project. You should find the appropriate Django version for the project.
要修复此错误，您应该为项目安装兼容版本的 Django 或将manage.py不使用的新样式更新为execute_manager：https: //docs.djangoproject.com/en/stable/releases/1.4/#updated-default- project-layout-and-manage-py最有可能的manage.py是，如果您与 1.6 不兼容，那么项目的其余部分也不兼容。您应该为该项目找到合适的 Django 版本。

@Mark Lavin explained nicely what the error means and how it arises. I think I've just discovered why others may also get this error message so leaving it here for the record.
@Mark Lavin 很好地解释了错误的含义以及它是如何产生的。我想我刚刚发现为什么其他人也可能会收到此错误消息，因此将其留在这里以作记录。
I'm assuming you're running this from within a virtual environment.
我假设您在虚拟环境中运行它。
When starting a new Django project, if you run django-admin startproject <myproject>, you are invoking the global installation of Django. If, as in my case, it comes from a stale repo, it may be an old version - in my case:
当启动一个新的 Django 项目时，如果你运行django-admin startproject <myproject>，你正在调用 Django 的全局安装。如果，就像我的情况一样，它来自一个陈旧的回购，它可能是一个旧版本 - 在我的情况下：
>> django-admin --version
>> 1.3.1
If you want to run Django from within a virtual environment, then you need to invoke it with django-admin.py startproject <myproject>. This way, you get a Django project with the version corresponding to your localinstallation:
如果要在虚拟环境中运行 Django，则需要使用django-admin.py startproject <myproject>. 这样，您将获得一个版本与您本地安装对应的 Django 项目：
>> django-admin.py --version
>> 1.6.6

I was getting this error because I had an old version of django-admin.pyin my /usr/local/binfolder and I had forgotten to create a new virtualenv for my new project.
我收到这个错误是因为我的文件夹中有一个旧版本，django-admin.py我/usr/local/bin忘记为我的新项目创建一个新的 virtualenv。
Remember that the steps for a new project should be:
请记住，新项目的步骤应该是：
- First create a new virtualenv for your new project:
mkvirtualenv <mynewproj> - Update the Python version for your virtualenv if necessary:
virtualenv --python $(which python3.6) ~/.virtualenvs/<mynewproj> - Then create your Django project folder structure:
django-admin startproject <django project name>
- 首先为你的新项目创建一个新的 virtualenv：
mkvirtualenv <mynewproj> - 如有必要，更新您的 virtualenv 的 Python 版本：
virtualenv --python $(which python3.6) ~/.virtualenvs/<mynewproj> - 然后创建您的 Django 项目文件夹结构：
django-admin startproject <django project name>
I also deleted my old obsolete /usr/local/bin/django-admin.pybecause it was created before I discovered the joys of virtualenv.
我还删除了我的旧过时，/usr/local/bin/django-admin.py因为它是在我发现virtualenv.
