Linux升级Python提示Tkinter模块找不到解决

一、安装tkinter

在Linux中python默认是不安装Tkinter模块，

[root@li250-193 ~]# pythonPython 2.6.6 (r266:84292, Feb 22 2013, 00:00:18) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> import TkinterTraceback (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 tkinter2 ...3 [root@li250-193 ~]# python4 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 linux26 Type "help", "copyright", "credits" or "license" for more information.7 >>> import Tkinter8 >>>

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 -V2 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-2.7.43 [root@li250-193 Python-2.7.4]# ./configure4 ...5 [root@li250-193 Python-2.7.4]# make6 ...7 [root@li250-193 Python-2.7.4]# make install8 ...

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]# 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 ^tktk-8.5.7-5.el6.x86_64tkinter-2.6.6-36.el6.x86_64[root@li250-193 Python-2.7.4]# rpm -qa | grep ^tcltcl-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

1
[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

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)

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

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 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
