先从pip和Scripts文件夹说起
pip是python的包管理工具，Scripts是python根目录下的一个文件夹。我们家下载好的要安装的四个文件都放在Scripts文件夹中。
如果一切顺利，直接在windows命令行进入到Scripts文件夹下使用
pip install xxx.whl命令即可安装。
此处给出一个良心网站：https://www.lfd.uci.edu/~gohlke/pythonlibs/
它里面拥有大量的做python开发需要用到的包。
在官网下载Numpy安装是没有问题的，但是当我们再安装从官网下载的Scipy时会报错。
原因：看到有网友说Scipy依赖numpy-1.16.5+mkl-cp36-cp36m-win_amd64.whl（找到自己适合的版本）；所以我们先安装这个包。
用pip -m pip install -U pip 将pip更新到最新版本（可以用pip show pip查看自己的pip版本，不更新可能在安装包时提示更新，但是给出的语句是：python -m pip install --upgrade pip ，但是我自己的不好使，也有人说如果是python3.X就用：python3 -m pip install --upgrade pip；我的python确实是python3.X但是也不好使，最后就选择了pip -m pip install -U pip，它可以卸载以前的旧版本并且更新到最新版本）
完事之后在用python命令进入到python环境中
import pip._internal
print(pip._internal.pep425tags.get_supported())
查看自己适合什么样类型的包，去上面给出的网站中下载。
下载完之后就可以安装了：
