windows下很多库安装不方便，主要是编译C之类的。
之前这样做：
1去https://www.lfd.uci.edu/~gohlke/pythonlibs/ 下载各种版本编译好的.whl
2 pip install XXX.whl 。
但是用pipenv就报各种hash256错误
比如
Installing dependencies from Pipfile.lock (f6c5bf)▒▒

Will try again.
去官网，发现这个bug 1年前就讨论半天了，也没见解决：
Cannot install from a local wheel #914
去stackoverflow上看到这样：https://stackoverflow.com/questions/51528441/pipenv-how-to-handle-locally-installed-whl-packages
1打开https://www.lfd.uci.edu/~gohlke/pythonlibs/
2chrome浏览器按F12 开启控制台，点击要下载的文件，控制台上显示文件网址
3复制这个地址，用pipenv安装形如
pipenv install https://download.lfd.uci.edu/pythonlibs/l8ulg3xw/aiohttp-3.3.2-cp36-cp36m-win_amd64.whl
但这么干仍然有错误，最新官网作者回复，似乎不太重要
THESE PACKAGES DO NOT MATCH THE HASHES FROM Pipfile.lock #2863
Given that the wheel is from PyTorch it very well might be that they simply changed the wheel and now the hash is different. This is completely outside of our control and exactly what pipenv is designed to catch. If you don't mind, just re-lock with
pipenv lock.
