我现在正在制作一个应用程序。我想使用flask_mysqldb连接到我的数据库。我正在佛罗里达州创造我的环境。但当我尝试下载flask_mysqldb时，我遇到了一个奇怪的错误。我在网上搜索这个问题，但似乎没有找到任何解决方案。或者任何像我这样的问题。我用来安装flask_mysqldb的命令是：
pip install flask_mysqldb
这是我得到的错误：

我使用的是Windows 10。
Flask_mysqldb依赖于mysqlclient python，该python说明了在Windows:上安装
在Windows上构建mysqlclient非常困难。但也有一些二进制轮子，你可以很容易地安装。
以下是当前版本的轮子列表：
https://pypi.org/project/mysqlclient/1.4.6/#files
你可以下载适合你的平台的，然后用pip install filename.whl安装。然后你应该可以安装flask_mysqldb而不会出现错误。
