python psutil.cpu_times_percent（）。guest_nice AttributeError：“ scputimes”對象沒有屬性“ guest_nice”

Question

我在linux機器（centos 6.10）python 2.6上使用。 我正在嘗試安裝使用python的psutil模塊的工具，因此我也安裝了psutil模塊：

yum install python-psutil.x86_64
...
yum info python-psutil.x86_64
Installed Packages
Name        : python-psutil
Arch        : x86_64
Version     : 0.6.1
Release     : 1.el6
Size        : 354 k
Repo        : installed
From repo   : epel
Summary     : A process and system utilities module for Python
URL         : http://psutil.googlecode.com/

Description : psutil is a module providing an interface for retrieving information on all
        : running processes and system utilization (CPU, memory, disks, network, users) in
        : a portable way by using Python, implementing many functionalities offered by
        : command line tools such as: ps, top, df, kill, free, lsof, free, netstat,
        : ifconfig, nice, ionice, iostat, iotop, uptime, pidof, tty, who, taskset, pmap.

但是，在工具本身中，我遇到了下一個錯誤：

ERROR:  AttributeError: 'module' object has no attribute 'get_sysinfo'
ERROR:  AttributeError: 'scputimes' object has no attribute 'guest_nice'

當我嘗試將psutil導入python`s shell時，出現下一個錯誤：

>>> import psutil
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.6/site-packages/psutil/__init__.py", line 64, in     <module>
    import psutil._pslinux as _psplatform
  File "/usr/lib64/python2.6/site-packages/psutil/_pslinux.py", line 89, in     <module>
    TOTAL_PHYMEM = _psutil_linux.get_sysinfo()[0]
AttributeError: 'module' object has no attribute 'get_sysinfo'

因此，我從pypi網站下載了psutil版本5.4.7的源代碼，並將其手動安裝在服務器上。 現在，當我導入模塊時，出現下一個錯誤：

>>> import psutil
Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
  File "psutil/__init__.py", line 101, in <module>
    from . import _pslinux as _psplatform
  File "psutil/_pslinux.py", line 26, in <module>
    from . import _psutil_linux as cext
ImportError: cannot import name _psutil_linux

=============

更新

所以用yum刪除psutil並用pip安裝后，我可以導入模塊，但是出現下一個錯誤：

>>> from psutil import cpu_times_percent, cpu_percent, cpu_count
>>> from os import getloadavg
>>> from psutil import cpu_times_percent, cpu_percent, cpu_count
>>> ct = cpu_times_percent()
>>> ct.guest_nice
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'scputimes' object has no attribute 'guest_nice'

我要安裝的工具出現錯誤...我應該檢查什么？
