centos需要同时yum install zbar-devel

centos只pip3 install pyzbar的话会报错

再yum install zbar-devel就没问题了

在readme里提醒一下吧（）

我知道是我的问题centos已经停止维护了我再也不用centos了我已经熟读并背诵下次一定选debian

如果yum install zbar-devel出现报错Could not resolve host: mirrors.tencentyun.com; Unknown error的话那是因为根据gocq的提示，手动修改了dns地址导致无法解析这个腾讯云的内网域名。需要去/etc/yum.repos.d目录，换一个CentOS-Base.repo（百度cnetos7更换yum源），再把CentOS-Epel.repo里的所有http://mirrors.tencentyun.com/换成http://mirrors.cloud.tencent.com/，然后yum install zbar-devel

centos √都不用
