我正在尝试使用virtualenvwrapper创建一个django项目。我已经安装了virtualenvwrapper和virtualenvwrapper.django模板。但是，每当我尝试使用mkproject命令创建django项目时，都会出现标题中提到的错误。这是我的终端输出：
$ mkproject -t django todolist

该环境中的pip软件包列表：
(todolist) ➜ todolist pip list
Package Version
---------- -------
Django 2.1.7
pip 19.0.3
pytz 2018.9
setuptools 40.8.0
wheel 0.33.1
如您所见，Django已安装。另外，当我尝试在该环境下手动创建django项目时，也会收到相同的消息：
(todolist) ➜ django-code django-admin startproject mysite
Traceback (most recent call last):
File "/Users/tanmay/.virtualenvs/todolist/bin/django-admin", line 6, in <module>

我在做什么错了？
