It seems like you have not installed django in the virtual environment. You need to install all the dependencies in your virtual environment. try using pip:

好像你还没有在虚拟环境中安装django。您需要在虚拟环境中安装所有依赖项。尝试使用pip：

pip install Django

you can find more details here https://docs.djangoproject.com/en/1.10/topics/install/.

After some digging, it seems we are not able to add a new Python version into an existing virtualenv. So, I created a new virtual environment using the command

经过一番挖掘，似乎我们无法在现有的virtualenv中添加新的Python版本。因此，我使用该命令创建了一个新的虚拟环境

virtualenv -p python3.5 project-name

virtualenv -p python3.5项目名称

Here -p specifies which python you want in the environment. Although the default python and python3 are also included, which is a good thing. I then copied my existing django project there, and installed all the dependencies with pip3 install -r requirements.txt. I used pip3 because I am using python3.5.

这里-p指定你想要在环境中使用哪个python。虽然默认的python和python3也包含在内，这是一件好事。然后我复制了我现有的django项目，并使用pip3 install -r requirements.txt安装了所有依赖项。我使用pip3因为我使用的是python3.5。

After this, doing a python3.5 manage.py runserver worked like it's supposed to. Hope this helps someone.

在此之后，做一个python3.5 manage.py runserver就像它应该的那样工作。希望这有助于某人。
