直接pip install gmpy2 存在如下报错

正确安装方法
1.查看本机python环境的版本
进入cmd，输入python
Python 3.7.6 (tags/v3.7.6:43364a7ae0, Dec 18 2019, 23:46:00) [MSC v.1916 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.
如上代码块可知，该python版本为win32位下的3.7.6
2.进入下方网站安装轮子，即wheel
https://www.lfd.uci.edu/~gohlke/pythonlibs/
3.全局搜索gmpy2
命名规范如下，根据自己的python版本下载对应的轮子
cp27代表2.7版本 cp36代表3.6版本 amd64代表64位 win32代表32位
4.下载好后，将轮子复制到pythn环境下的scripts目录下
5.打开cmd进入刚刚的scripts文件下
执行以下命令
pip install + 轮子文件夹所在路径 轮子路径
如上图显示，gmpy2以及安装成功
pycharm安装方法大致同上
首先查看pycharm使用的解释器版本和路径
接着将轮子丢进pycharm使用解释器的scripts中
然后进入cmd安装即可
如图所示，安装成功
