由于本人也是初学Python和django。本人使用的Python版本是3.7所以连接MySQL数据库需要安装数据驱动，对应Python3的数据驱动是mysqlclient。因此本人习惯性的使用命令pip install mysqlclient，结果安装失败

You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

然后就从网上寻找各种安装的文章，然后发现一篇文章说

到这个地址下载自己版本对应的资源到本地，然后进行安装https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient

然后我进入下载的资源所在目录

然后使用命令安装，结果仍然失败

然后又苦苦的寻找各种解决办法和答案，幸运的是又让我找到一篇文章是这么说的

下载32位的版本安装能成功，因此我有继续下载如下图中的版本

然后继续执行安装的命令，出人意料，竟然成了！至于原因，因为我的Python版本是32。因此分享给大家，大家有问题欢迎留言评论~
