今天需要安装一个软件时，发现系统的python版本太低，出现下面的错误：
- File "setup.py", line 39
- with open("ChangeLog", "w") as changelog_file:
- ^
- SyntaxError: invalid syntax
google后发现这个软件需要python2.6.5
centos5的自带python为2.4.3
下面是我升级的python的步骤
- wget http://mirrors.sohu.com/python/2.6.5/Python-2.6.5.tar.bz2
- tar -jxvf Python-2.6.5.tar.bz2
- cd Python-2.6.5
- ./configure
- make;make install
测试
- [root@UNI-HEB-1-N015-bind-006 swift-1.3.0]# rm /usr/bin/python
- rm: remove regular file `/usr/bin/python'? y
- [root@UNI-HEB-1-N015-bind-006 swift-1.3.0]# ln /usr/local/bin/python2.6 /usr/bin/python
- [root@UNI-HEB-1-N015-bind-006 swift-1.3.0]# python
- Python 2.6.5 (r265:79063, Jun 29 2011, 12:30:49)
- [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2

安装好了
不过在执行yum的时候，发现无法执行，
出现下面错误
- [root@UNI-HEB-1-N015-bind-006 swift-1.3.0]# yum search apt
- 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:
- 2.6.5 (r265:79063, Jun 29 2011, 12:30:49)
- [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)]
- If you cannot solve this problem yourself, please go to
- the yum faq at:
- http://wiki.linux.duke.edu/YumFaq
改回来就好了
- [root@UNI-HEB-1-N015-bind-006 swift-1.3.0]# rm /usr/bin/python
- rm: remove regular file `/usr/bin/python'? y
- [root@UNI-HEB-1-N015-bind-006 swift-1.3.0]# ln -s /usr/bin/python2.4 /usr/bin/python
这个问题暂时未解决，大家先用/usr/local/bin/python2.6执行吧
