[Python Notes]-bash: python: command not found

question:

In the server environment, when using the python command, the prompt: -bash: python: command not found

Check the server python version, usually in the /usr/bin directory. Enter the following command in the terminal: 

find /usr/bin -iname 'python*'

 Get the output:

/usr/bin/python3.10
/usr/bin/python3

reason:

Python is installed normally and no soft links are configured.

Solution

Create a soft link according to the python version. The command is as follows: (such as python3.10, change it to your own according to the version information)

ln -s /usr/bin/python3.10 /usr/bin/python

Sudo permissions may be required.

Enter python -V to verify:

Python 3.10.6

ls -l /usr/bin/python*

lrwxrwxrwx 1 root root      16 Jun 26 06:31 /usr/bin/python -> /usr/bin/python3
lrwxrwxrwx 1 root root      10 Aug 18  2022 /usr/bin/python3 -> python3.10
-rwxr-xr-x 1 root root 5912968 May 29 11:10 /usr/bin/python3.10

Others: if present

ln: failed to create symbolic link '/usr/bin/python': File exists

Just add an f to the command ln -sf

ln -sf /usr/bin/python3.10 /usr/bin/python
