So the installation is complete. But because some software, such as node. js, relies on python2.7, you need to modify the system path at this point. python command points to 2.7. Version 3:

[Root@/Usr/Local/Bin]# cp/usr/bin/python/usr/bin/python.bak.2014.11.16[Root@/Usr/Local/Bin]# Rm/usr/bin/python[Root@/Usr/Local/Bin]# ln-s/usr/local/bin/python2.7/usr/bin/python

So, if you encounter yum problems, the following "there was a problem importingone of the Python modules":

[Root@~/Software/Python-2.7.3]# Yum Search bZIPThere is a problem importing one of the Python modulesrequired to run yum. The error leading to this problem was:No module namedYum pleaseInstalla Packagewhichprovides this module, orverify the module is installed correctly. It' s possible that the above module doesn 'T match thecurrent version of Python,whichis:2.7.3(default, Nov -  the,  -: A: $) [GCC 4.4.720120313 (Red Hat 4.4.7-4)]If You cannot solve this problem yourself and go to theYumFAQ at:http://yum.baseurl.org/Wiki/Faq

This is because Yum relies on older versions of Python, which can be fixed as follows:

[root@~/software/Python-2.7.3] # Vim/usr/bin/yum

Modify the first line of the command line to point Python to the specified version:

  1 #!/usr/bin/python2.6  2Import SYS3Try:4ImportYum
