I updated from Django 1.5.8 to 1.7:

This is my error message.

这是我的错误信息。

But when I run

但当我运行

python
import django
print(django.get_version())

I get 1.7. Can I use the version like that or do I have to reinstall it? Will it work?

我得到1.7。我可以使用这样的版本吗?还是需要重新安装?会工作吗?

Thank you!

谢谢你!

This is because the first time you installed django, you did sudo pip install django, which has installed django in your global Python interpreter as the root user (or the superuser).

这是因为在第一次安装django时，您做了sudo pip安装django, django已经在全局Python解释器中作为根用户(或超级用户)安装了django。

You can only have one version of django in your global Python interpreter, so once you upgrade it, any of your django applications that are using the global Python interpreter (in other words, not using a virtual environment) will be automatically upgraded to 1.7

您只能在您的全局Python解释器中有一个django版本，因此一旦您升级它，任何使用全局Python解释器(换句话说，不使用虚拟环境)的django应用程序都将自动升级到1.7。

If you don't have any other django projects, then this doesn't really have any negative effects - but as a best practice, you should use virtual environments so that you can easily test versions of libraries.

如果您没有任何其他django项目，那么这实际上没有任何负面影响——但是作为一种最佳实践，您应该使用虚拟环境，以便能够轻松地测试库的版本。

To solve your immediate problem, you need to sudo pip install -U django which will upgrade django to the latest stable release.

要解决当前的问题，您需要sudo pip安装-U django，它将django升级到最新的稳定版本。
