当我试图创建一个新的应用程序时，我也遇到了同样的问题。如果你写python manage.py startapp myapp，那么它会寻找usr/bin/python。但是你需要这个“python”，它位于你的虚拟env路径的/bin目录下。我通过提到virtualenv的python路径来解决这个问题，就像这样:

<env path>/bin/python manage.py startapp myapp

此问题的另一个可能原因是您的操作系统默认运行python3。

你必须显式地执行:python2 manage.py

或者你需要编辑manage.py的shebang，就像这样:

#!/usr/bin/env python2

或者如果你使用python3:

#!/usr/bin/env python3

解决了它! !

在搜索了很长时间并尝试了所有这些都没用的建议之后，我终于找到了适合我的设置的解决方案。

我的设置/场景:

窗户,Python27 我的django项目是通过svn签出的 当在新文件夹中运行python manage.py runserver时，我得到了导入错误 python manage.py runserver曾经在原始文件夹中工作(我将从原始文件夹提交更改)，直到我删除它

解决方案

删除manage.py目录下所有名为django的文件夹

这是正确的…当我删除文件夹“django”，它只包含__init__.py文件…我可以再次运行服务器!

不知道为什么

对我来说，我的服务器使用的是Python 2.4。我只是查找了安装在我服务器上的Python 2.7，并创建了一个别名。

alias python=python2.7

如果你想知道更多，我在这里找到了解决方案

它是这样的:

你已经创建了一个虚拟环境，django模块只属于这个虚拟环境。由于virtualenv将自己与其他所有东西隔离，因此您看到了这个。

阅读以下内容以获得进一步帮助:

http://www.swegler.com/becky/blog/2011/08/27/python-django-mysql-on-windows-7-part-i-getting-started/

1.你可以切换到虚拟环境所在的目录，然后运行django模块。

2.或者你也可以通过运行pip或easy_install将django全局安装到你的python->site-packages中

使用pip命令:pip安装django

然后这样做:

进口django Print (django.get_version())(取决于你使用的python版本。适用于python 3+系列)

然后你可以运行这个: Python manage.py runserver 在浏览器中输入:localhost:8000进行检查 你应该会看到django powered page。

希望这能有所帮助。

================================== 解决方案 =========================================

第一个转到：虚拟环境

通过运行命令: 源bin /激活

然后安装django，因为你会得到与import django相关的错误:

pip install django

然后运行:

python manage.py runserver

(注意:请将'runserver'更改为您要运行的程序名称)

对于同样的问题，它在我的案例中起了作用。 ================================== 剧情简介 =========================================
