[Errno 2] No such file or directory: 'python3'--following Python Crash Course 2nd ed

#1

I know there are related posts but I have studied them without success. I’m on a Mac running Mojave 10.14.6
I’ve installed python 3; at the terminal,
$python3
gives:
Python 3.9.4 (v3.9.4:1f2e3088f3, Apr 4 2021, 12:32:44)
and I can run python3 without problems.
Trying to configure sublime text as per “python crash course” 2nd edition, following the steps carefully multiple times, when I build my “hello_world.py” code I get:
[Errno 2] No such file or directory: ‘python3’
[cmd: [‘python3’, ‘-u’, ‘/Users/spencerri/Dropbox/python_work/hello_again.py’]]
[dir: /Users/spencerri/Dropbox/python_work]
[path: /usr/bin:/bin:/usr/sbin:/sbin]
[Finished]
Note: my Python3.sublime-build file reads:
{
“cmd”: [“python3”, “-u”, “$file”],
}

I’m out of (very elementary) ideas and would greatly appreciate any insight! I am working around this by creating code in the TextEdit utility and changing the .txt to .py; this actually works fine but I’d like to use the additional functionality of sublime text.

If you type where python3 in the terminal, does it exist in one of the locations that are on your PATH:

[path: /usr/bin:/bin:/usr/sbin:/sbin]

Well, I have found the solution after going around the net a lot.
I only had to change the code in the file “Main.sublime-menu” found in the directory:
/Users/User/Library/Application Support/Sublime Text/Packages/SublimeREPL/config/Python/Main.sublime-menu
by this other code:

The answer I found is in this link: https://t.ly/KVQOq

Hi @OdatNurd
First, sorry for my bad english.

I’m new coding and I’m trying to execute Python in Sublime Text 3. I work with mac (Monterrey 12.6.6)
I have installed this version of python: /Applications/Python 3.11

I Think that I have the same problem than @RGS but I don’t Know how to fix it. See the image attached here down.
