一、安装tkinter
在Linux中python默认是不安装Tkinter模块，
[root@li250-193 ~]# python Python 2.6.6 (r266:84292, Feb 22 2013, 00:00:18) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import Tkinter Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named Tkinter >>>
我们安装Tkinter模块
1 [root@li250-193 ~]# yum -y install tkinter 2 ... 3 [root@li250-193 ~]# python 4 Python 2.6.6 (r266:84292, Feb 22 2013, 00:00:18) 5 [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2 6 Type "help", "copyright", "credits" or "license" for more information. 7 >>> import Tkinter 8 >>>
二、升级Python
Linux的Python版本默认都不叫低
查看Python版本
1 [root@li250-193 ~]# python -V 2 Python 2.6.6
DOWN新版本
1 [root@li250-193 ~]# wget http://www.python.org/ftp/python/2.7.4/Python-2.7.4.tgz
解压安装
1 [root@li250-193 ~]# tar -xf Python-2.7.4.tgz 2 [root@li250-193 ~]# cd Python-2.7.4 3 [root@li250-193 Python-2.7.4]# ./configure 4 ... 5 [root@li250-193 Python-2.7.4]# make 6 ... 7 [root@li250-193 Python-2.7.4]# make install 8 ...
看看新版本Python是否可以使用Tkinter？
[root@li250-193 Python-2.7.4]# ./python
Python 2.7.4 (default, Apr 12 2013, 08:03:09) [GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
Traceback (most recent call last): File "<stdin>", line 1, in <module>
File "/root/Python-2.7.4/Lib/lib-tk/Tkinter.py", line 39, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter>>>提示找不到tkinter模块？看看旧版的是不是正常
root@li250-193 Python-2.7.4]# find /usr -name *tkinter.so /usr/lib64/python2.6/lib-dynload/_tkinter.so
找到一个，在2.6旧版本的目录下，估计是因为新版本库指向问题。于是认真读了README说明。重新配置安装
三、正确安装新版Python
首先修改Setup.dist文件
_tkinter _tkinter.c tkappinit.c -DWITH_APPINIT -L/usr/local/lib -I/usr/local/include -ltk8.5 -ltcl8.5 -lX11
以上第四行
-ltk8.5 -ltcl8.5 默认是 8.2 ，请你系统实际tcl/tk版本修改
[root@li250-193 Python-2.7.4]# rpm -qa | grep ^tk tk-8.5.7-5.el6.x86_64 tkinter-2.6.6-36.el6.x86_64 [root@li250-193 Python-2.7.4]# rpm -qa | grep ^tcl tcl-8.5.7-6.el6.x86_64
我系统中装的是8.5，所以这里我改成了8.5
保存退出
安装tck-devel、tk-devel
|

|
[root@li250-193 Python-2.7.4]# yum -y install tcl-devel tk-devel
|
开始配置安装

...[root@li250-193 Python-2.7.4]# make install

看下新版Python是否可以使用tkinter模块

>>> import Tkinter

已经没问题，旧版再看看

[root@li250-193 Python-2.7.4]# /usr/bin/python2.6

>>> import Tkinter
>>> |
也没问题
如果直接敲入python -V查看版本是不是最新的，如果不是可以这么干：
which出python命令路径
|
1
2
|
[root@li250-193 Python-2.7.4]# which python
/usr/local/bin/python |
cp 过去
|
1
|
[root@li250-193 Python-2.7.4]# cp python /usr/local/bin/python
|
四、升级Python引起yum版本无法使用的问题解决
不少童鞋安装后就
cp python /usr/bin/python
导致yum时就提示

[root@lee ~]# yum
There was a problem importing one of the Python modulesrequired to run yum. The error leading to this problem was: No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.It‘s possible that the above module doesn‘t match the
current version of Python, which is:
2.7.4 (default, Apr 9 2013, 17:12:56) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)]If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq

因为yum头部默认制定python脚本的路径就是
#! /usr/bin/python
你把旧版的python替换后就是用不了，不知道为何新版Python不能被yum识别，目前唯一最好解决的方法就是修改yum头部声明
改成
#! /usr/bin/python2.6
即可，这里的python2.6是我centos默认版本，大家的默认版本是多少请按实际情况修改即可
