python加载包出错_python导入Pmw包运行提示一下错误

我是Centos7.2的系统 python版本是2.7.5

错误提示:

Traceback (most recent call last):

File "./py020.py", line 14, in

'min':2, 'max':12})

File "/usr/lib/python2.7/site-packages/Pmw/Pmw_1_3_3/lib/PmwCounter.py", line 126, in init

self.initialiseoptions()

File "/usr/lib/python2.7/site-packages/Pmw/Pmw_1_3_3/lib/PmwBase.py", line 594, in initialiseoptions

'" for ' + self.__class__.__name__

KeyError: 'Unknown option "extryfield_validate" for Counter'

源码如下

!/usr/bin/env python

from Tkinter import Button, END, Label, W

from Pmw import initialise, ComboBox, Counter

top = initialise()

lb = Label(top, text='Animals (in pairs; min: pair, max: dozen)')

lb.pack()

ct = Counter(top, labelpos=W,label_text='Number:',

datatype='integer', entryfield_value=2,

increment=3, extryfield_validate={'validate':'integer',

'min':2, 'max':12})

ct.pack()

cb = ComboBok(top,labelpos=W,label_text='Type:')

for animal in ('dog', 'cat', 'hamster', 'python'):

cb.insert(end, animal)

cb.pack()

qb = Button(top,text+'QUIT',

command = top.quit, bg = 'red', fg = 'white')

qb.pack()

top.mainloop()

希望前辈指导一下
