Linux how to delete the version of Python that comes with the system
This article mainly explains how Linux deletes the system's own version of Python, the content is clear, interested friends can learn, I believe it will be helpful after reading.
1. Uninstall python (prevent clean uninstall)
Rpm-qa | grep python | xargs rpm-ev-- allmatches-- nodeps # forcibly delete installed programs and their associations
Whereis python | xargs rm-frv # Delete all remaining files # xargs, allowing you to execute certain other commands on the output
two。 Uninstall yum
Rpm-qa | grep yum | xargs rpm-ev-- allmatches-- nodeps
Rm-rf / etc/yum.repos.d/*
Whereis yum | xargs rm-frv
3. Verify that the deletion is clean
Whereis python # verifies deletion. No result should be returned.
Whereis yum
4. Install python and yum
Software download address (my system is centos 7.5.1804)
Check the linux system version: cat / etc/redhat-release
Http://vault.centos.org/7.5.1804/os/x86_64/Packages/
The required files are as follows: (just download the corresponding version of your own system)
