在百度了许久之后，发现找到的解决方案并不适用，于是我仔细地查看报错信息，发现了

Building wheels for collected packages: simplejson
  Building wheel for simplejson (setup.py) ... error

应该是因为simplejson安装失败导致了这个问题，所以尝试安装simplejson模块，但报了相同的错误，现在可以确定是安装simplejson模块出错导致了我们遇到的错误，猜测应该是pip下载的simplejson版本不兼容，以下是我的python版本

Python 3.7.3 (default, Apr 24 2019, 15:29:51) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32

我使用的是anaconda的python环境，版本问题的话就好解决了

conda install simplejson

然后再安装我们的django-rest-swagger

pip install django-rest-swagger

安装成功

Installing collected packages: django-rest-swagger
Successfully installed django-rest-swagger-2.2.0

如果不是基于anaconda的python环境该怎么做呢，我们可以去这个网站https://www.lfd.uci.edu/~gohlke/pythonlibs/#simplejson寻找对应版本的whl文件，然后pip install 即可。
别问我为什么不去官网找对应文件,不知道是我找错了还是什么原因,我没在官网找到我所需要的版本…
