Python升级提示Tkinter模块找不到的解决方法

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

[root@li250-193 ~]# yum -y install tkinter

...

[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

>>> import Tkinter

>>>

二、升级Python
Linux的Python版本默认都不叫低
查看Python版本

[root@li250-193 ~]# python -V

Python 2.6.6

DOWN新版本

[root@li250-193 ~]# wget http://www.python.org/ftp/python/2.7.4/Python-2.7.4.tgz

解压安装

[root@li250-193 ~]# tar -xf Python-2.7.4.tgz 

[root@li250-193 ~]# cd Python-2.7.4

[root@li250-193 Python-2.7.4]# ./configure

...

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

...

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

...

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 linux2

Type "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]# 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

>>>

旧版的没问题，难道需要yum install tkinter一次？

[root@li250-193 Python-2.7.4]# yum install tkinter

Loaded plugins: fastestmirror, security

Loading mirror speeds from cached hostfile

 * base: mirror.team-cymru.org

 * extras: mirror.team-cymru.org

 * updates: mirror.team-cymru.org

Setting up Install Process

Package tkinter-2.6.6-36.el6.x86_64 already installed and latest version

Nothing to do

提示已安装，看来不是tkinter的问题，看看tkinter模块在哪里？

[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

[root@li250-193 Python-2.7.4]# vim Modules/Setup.dist

找到下面这几行，把前面的井号去掉打开它

_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]# ldconfig

[root@li250-193 Python-2.7.4]# ./configure

...

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

...

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

...

看下新版Python是否可以使用tkinter模块

[root@li250-193 Python-2.7.4]# ./python

Python 2.7.4 (default, Apr 12 2013, 08:49:11) 

[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import Tkinter

>>>

已经没问题，旧版再看看

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

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

>>>

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

[root@li250-193 Python-2.7.4]# which python

/usr/local/bin/python

cp 过去

[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 modules

required 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

   

 

[root@lee ~]#

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
