Probably, pipinstalls packages into dist-packagesdirectory, which is not included into PYTHONPATHenvironment variable. You have a couple of solutions:
可能pip将软件包安装到dist-packages目录中，该目录未包含在PYTHONPATH环境变量中。你有几个解决方案：
- Create and configure
virtualenvfor your project, before usingpip. This is the most Pythonic way Try to install
Djangousing built-in pip module:python -m pip install djangoThis command should install packages into
site-packagesdirectory.- You may also add
dist-packagesto yourPYTHONPATH. This question should help you: How to globally modify the default PYTHONPATH (sys.path)?
- 创建和配置
virtualenv使用前为您的项目，pip。这是最 Pythonic 的方式 尝试
Django使用内置 pip 模块安装：python -m pip install django此命令应将软件包安装到
site-packages目录中。- 您也可以添加
dist-packages到您的PYTHONPATH. 这个问题应该对你有帮助：如何全局修改默认的 PYTHONPATH (sys.path)？

For Mac users; If you've previously downloaded and installed python3, just running pythonvia the terminal shell defaults to using the pre-installed python v2, which will not recognise your installation of django (unless you install it via the python2 module) and you'll probably get an error when you check the version:
对于 Mac 用户；如果您之前已经下载并安装了 python3，仅python通过终端 shell运行默认使用预装的 python v2，它不会识别您安装的 django（除非您通过 python2 模块安装它）并且您可能会得到检查版本时出错：
$ python
>>> from django import get_version
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named django
Try starting python using:
尝试使用以下命令启动 python：
$ python3
Then try:
然后尝试：
>>> from django import get_version
>>> get_version()
You should get the output:
你应该得到输出：
'2.0.3'

I had given the dependency in requirements.txtas Django==2.0.7. So after activating the virtual environment, if you are receiving the message, try installing the requirements:
我已经在requirements.txtas 中给出了依赖Django==2.0.7。所以激活虚拟环境后，如果收到消息，尝试安装需求：
pip install -r requirements.txt

You need to close the other active virtual environment in your machine if you're using virtualenv, and make sure django installed. Go to python3 interpreter and run this:
如果您使用的是 virtualenv，则需要关闭机器中的其他活动虚拟环境，并确保已安装 django。转到python3解释器并运行：
>>>from django import get_version
>>>get_version()
make sure it show you this '2.1.4'
确保它显示你这个'2.1.4'
