[已解决]关于Python3使用 CentOS7使用SNMP工具的问题

LuckFly

各位鱼油
          我想问个问题，我在CentOS7安装完Python3后，想使用netsnmp这个工具，但那是我经过各种坎坷安装成功以后，发现Python2没有问题，Python3无法使用，请问各位鱼油，有没有类似的经验，求教。
实验目的：是为了使用Python做设备巡检，如路由器，交换机，服务器等等。

Collecting netsnmp

pip3 install python3-netsnmp

因为你装到python2里面去了，要装到python3里面去，可以使用pip3 install netsnmp

尝试使用安装，提示我没有找到相关的版本
[root@localhost ~]# pip3 install netsnmp
Collecting netsnmp
  Could not find a version that satisfies the requirement netsnmp (from versions: )
No matching distribution found for netsnmp
You are using pip version 19.0.3, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

更新pip发现是2版本
[root@localhost ~]# pip install --upgrade pip

这难道是我版本下的有问题么，是否和centos7有关系？
