raise ImportError, str(msg) + ‘, please install the python-tk package‘
ImportError: No module named _tkinter, please install the python-tk package

解決辦法：

Tkinter是Python的GUI widget。一般情況下Linux都沒有自帶，要自己安裝。

1、確定Tkinter沒有安裝：
>>> import Tkinter
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 41, in ?
raise ImportError, str(msg) + ‘, please install the python-tk package‘
ImportError: No module named _tkinter, please install the python-tk package
>>>

2、安裝Tkinter：
$sudo apt-get install python-tk

3、安裝成功：
>>> import Tkinter
>>>

Python的Tkinter庫的安裝
