Pipfile文件截取如下
[packages]
sasl = {version="==0.2.1", index="douban"}
直接执行pipenv install会报错

解决
遂到网上找到答案: Stack Overflow (这里这个只适合python2.7的哦)
从http://www.lfd.uci.edu/~gohlke/pythonlibs/#sasl 找到适合自己的版本 cp27 代表python2.7, cp37代表python3.7 以此类推. 我的是python3.7所以找到下面这个版本下载下来到电脑里. 再用pip安装.
pip install D:\documents\sasl-0.2.1-cp37-cp37m-win_amd64.whl
如果你用的是pipenv, 那么要将pip换成pipenv. 但是同时, pipenv会自动更改你的Pipfile形如下面:
sasl = {path = "D:/documents/sasl-0.2.1-cp37-cp37m-win_amd64.whl"}
所以这里需要注意, 如果你需要和其他人合作或者是在不同平台、电脑上都运行这个项目的话, 需要将这个改成原来从pip库中获取的样式, 不然就太不优雅且容易出错了.
