1 Problem description
yum install cmakeInstalling cmake using yum failed. The failure information is as follows:
[root@localhost]# yum install cmake
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
/root/anaconda3/lib/liblzma.so.5: version `XZ_5.1.2alpha' not found (required by /lib64/librpmio.so.3)
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:
2.7.5 (default, Oct 14 2020, 14:45:30)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq2 Problem analysis
From the analysis of the following sentence, we can draw the conclusion
/root/anaconda3/lib/liblzma.so.5: version `XZ_5.1.2alpha' not found (required by /lib64/librpmio.so.3)
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:
2.7.5 (default, Oct 14 2020, 14:45:30) This problem is mainly caused by the conflict between yum and anaconda3. The python version in the yum environment is 2.7, while the version in the anaconda3 environment is 3.x.
