ERROR: Cannot install flask-mysqldb==0.1.1, flask-mysqldb==0.2.0, flask-mysqldb==1.0.0 and                                                                                                                                               flask-mysqldb==1.0.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    flask-mysqldb 1.0.1 depends on mysqlclient>=1.3.7
    flask-mysqldb 1.0.0 depends on mysqlclient>=1.3.7
    flask-mysqldb 0.2.0 depends on mysqlclient
    flask-mysqldb 0.1.1 depends on mysqlclient

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

网上找了很多方法有的说安装wheel 有的方法是需要安装c++环境试了一边发现还是没有解决

也怀疑是python版本和包的不兼容

看报错信息是安装flask-mysqldb需要依赖mysqlclient包，

由于安装mysqlclient也出现报错，去官方文档查看需要安装以下两个工具

yum cài đặt python3-devel mysql-devel

再去执行pip install flask-mysqldb 大功告成
