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:
Verify that the Python executable exists: Use the
ls -l /usr/bin/python3command to confirm that the/usr/bin/python3file exists.Add execution permissions: If the file exists, add execution permissions to it using the
sudo chmod x /usr/bin/python3command. 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.
The above is the detailed content of How to solve the permissions problem encountered when viewing Python version in Linux terminal?. For more information, please follow other related articles on the PHP Chinese website!
How do you create multi-dimensional arrays using NumPy?Apr 29, 2025 am 12:27 AMCreate multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.
