View Python version permissions problem and solutions on Linux terminal

When executing the python --version command to view Python version in Linux terminal, you may encounter permission errors, such as: " bash: /usr/lib/command-not-found: /usr/bin/python3: bad interpreter: permission denied ". This article provides steps to resolve this issue.

First, try to execute the command with administrator privileges: sudo python --version . If the prompt " sudo: python: command not found ", it means that the system cannot find the Python command.

Next, check the environment variable PATH: echo $PATH . Even if the PATH variable contains Python paths (e.g. /usr/local/bin/python3:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/usr/bin/python3 ), the problem may still exist.

An error message indicates insufficient permissions. The solution is as follows:

1. Verify that the Python executable exists: Use the ls -l /usr/bin/python3 command to confirm that the /usr/bin/python3 file exists.

2. Add execution permissions: If the file exists, add execution permissions to it using the sudo chmod x /usr/bin/python3 command. This will resolve errors caused by insufficient permissions.

After completing the above steps, try the python --version or python3 --version command again to view the Python version information.
