关于pip安装libvirt-python的时候提示Package libvirt was not found in the pkg-config search path的问题解决方法

• 1、一开始以为是网络原因，尝试不同的版本也不行，【未果】
• 2、在网上查阅资料后说是缺少libvirt.py这个文件，建议从安装包中拷贝过来，但是这个是pip安装不同于其它的开源软件，所以这个也行不通，可以参考以下链接

• 3、直到看到有网友说是需要安装libvirt-devel之后，才恍然大悟，其实安装完这个包之后就有/usr/lib64/pkgconfig/libvirt.pc这个文件了

关键的一句You probably need libvirt-dev(el) package installed.，然后执行yum install -y libvirt-devel就没有问题了

错误提示如下：
