iotop 是通过 yum install iotop 安装的

Answer 1

我能够通过以下步骤更正此错误

1. 删除 yum 安装的 iotop - yum remove iotop
2. 安装 python 2.6 - yum install python26
3. 安装 iotop rpm - rpm -ivh http://guichaz.free.fr/iotop/files/iotop-0.4.1-1.noarch.rpm
4. 编辑/usr/bin/iotop
   • 将第一行#!/usr/bin/python修改为#!/usr/bin/python2.6
5. 运行iotop并享受
