centos默认python版本是2.6,升级到2.7后,发现yum不能用了
报错内容:
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:
2.7.10 (default, Aug 25 2017, 11:09:17)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
解决办法:
vi /usr/bin/yum
编辑首行,
#!/usr/bin/python
修改为
#!/usr/bin/python2.6
再次执行yum就没有问题啦
