CentOS上的iotop命令出错

14

在新安装的CentOS 7.5的终端中使用sudo iotop（最新版本0.6-2.el7）时，出现以下错误消息：

Traceback (most recent call last):
  File "/sbin/iotop", line 17, in <module>

    key, value = line.split(':\t', 1)
ValueError: need more than 1 value to unpack

任何想法如何解决此问题？

这个对我有用。使用者名称：Linux 4.4.0-127-通用＃153〜14.04.1-Ubuntu iotop版本：iotop 0.6 Phyton版本/usr/bin/python2.7

显然，最新的内核版本在/proc/(pid)/statusiotop期望的范围内引入了空行：

CapBnd: 0000001fffffffff
CapAmb: 0000000000000000
Seccomp:    0

SpeculationStoreBypass: vulnerable

作为修订的第零近似值，请编辑（以root用户身份），/usr/lib/python2.7/site-packages/iotop/data.py约为195：

def parse_proc_pid_status(pid):
    result_dict = {}
    try:
        for line in open('/proc/%d/status' % pid):
            if not line.strip(): continue
            key, value = line.split(':\t', 1)
            result_dict[key] = value.strip()
    except IOError:
        pass  # No such process

    return result_dict

当if not line.strip(): continue是新的。注意python没有明显的花括号，因此此行的缩进应与其下方的行相匹配。

与“ Pympler” Python软件包相同。第147行。if not entry.strip(): continue在解决该问题之前添加。pythonhosted.org/Pympler

只是为了补充已接受的答案（无法添加为注释，因为它们不允许多个空格）

搜索Python脚本的文件路径

sudo find ./usr/lib | grep iotop/data.py

替换为sed

sed -i '1n;/key, value = line/i\            if not line.strip(): continue' <script_path>

请小心，并在首次运行时检查一切正常。

对于我的系统，它是：

sudo sed -i '1n;/key, value = line/i\            if not line.strip(): continue' /usr/lib/python2.7/dist-packages/iotop/data.py
