事情的经过大概是这样的
服务器需要安装psutil工具来获取进程信息
然后搓了一顿的py命令，结果乘兴而来，特么的各种报错。。。。
服务器的系统是linux centos7.2，结果碰了一鼻子灰
第一阶段：服务器默认是安装的python2，然后pip还没有安装。。。
我就默默的yum install pip，慢慢悠悠安装后，提示需要升级pip，就从9升级到了20，大概是这么个版本，我不常用py，模糊记得是这样。
然后我pip install psutil，结果提示说，python2.7要寿终正寝。。。最好是更换新版本。。。我顿时一紧
第二阶段：那就正常打怪，不，正常安装py3吧。
yum install python3 python3-devel，同时也安装怕pip3，就是操作的时候各种警告提示，不管他，继续安装psutil
结果遇到了一片红，再三确认后，确实是一片红。。。安装不上，报错了。
错误在文章最后，有点长，见谅哈。
然后就挨着看错误，就看到了gcc的问题，看到是GCC在编译，那就是psutil有点特殊，安装的时候，还需要编译，我安装了一大推其他的工具，也没碰到个需要编译的。
第三阶段：本着缺啥补啥的原则，开始安装gcc
yum install gcc，安装后，再次安装psutil，就看到了久违的successful
总结：其实我最开始的时候，并没有仔细去看报错的信息，老以为版本不对，或者命令用的不对。然后五花八门的尝试了很多东西，都不见效。后来没辙，挨着一行一行的错误看，看看有啥特殊的提示没，然后就看到了gcc编译的错误。。。特么的我是眼瞎，没早一点看，哎。
最终BOSS被击败，以后多长点眼神。
我一个开发的搞运维，确实有点心累，没法子，我不干，谁干。那就先这样吧，赶紧写会代码压压惊！
