I've cloned a reactJs repository and after that, I wanted to run the " npm install " but when I was running it I got Syntax Error about using python

error code:

stack Error: Command failed: /opt/homebrew/bin/python3 -c import sys; print 
"%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack   File "<string>", line 1
gyp ERR! stack     import sys; print "%s.%s.%s" % sys.version_info[:3];

That code was evidently written for Python 2. – jonrsharpe Jun 21 '22 at 09:44
@jonrsharpe yes, your right, but the problem is homebrew does not have python 2 anymore, I just found python 3 because my MacBook has M1 Chip – Daniel Ef Jun 21 '22 at 09:48
macOS system Python (`/usr/bin/python`) is v2. – robertklep Jun 21 '22 at 09:52
@robertklep $> cd /usr/bin/python -------------------- cd: no such file or directory: /usr/bin/python – Daniel Ef Jun 21 '22 at 09:55
@robertklep not since 12.3 – jonrsharpe Jun 21 '22 at 09:58
You could update the code from Python 2 to Python 3 (and create a pull request). – jabaa Jun 21 '22 at 10:03
Hmm I'm still on 12.2… – robertklep Jun 21 '22 at 10:10
@robertklep so how can I execute it? – Daniel Ef Jun 21 '22 at 10:12
@jabaa how can I update it? – Daniel Ef Jun 21 '22 at 10:13
@DanielEf never mind, if you're on 12.3, apparently it doesn't exist anymore :( You may be able to find it still in `/System/Library/Frameworks/Python.framework/Versions/` but I'd expect it to be removed from there as well. You can try and use `pyenv` though: https://stackoverflow.com/a/67274521 – robertklep Jun 21 '22 at 10:13
Fix the code. It's written for Python 2. Rewrite it to Python 3. – jabaa Jun 21 '22 at 11:03
@robertklep I tried pyenv but it's not working too and it says python2 is not compatible with my CPU type – Daniel Ef Jun 21 '22 at 11:46
How large is the actual? Is it a dozen of lines containing `print` statements that have to be fixed or a codebase with millions of lines with complex code? Updating a simple script can be the easiest and quickest fix. Python 2 is dead. – jabaa Jun 21 '22 at 14:42
@jabaa cant get you, which scripts should update? – Daniel Ef Jun 22 '22 at 12:34
The script that contains `print "%s.%s.%s" % sys.version_info[:3]` should be updated to `print("%s.%s.%s" % sys.version_info[:3])` – jabaa Jun 22 '22 at 12:39
@jabaa where can I change this script? – Daniel Ef Jul 26 '22 at 12:22
You're trying to install an outdated package. Find out which package it is. Find that line in the package. Fix it. Either create a pull request or fork the project. Use the fixed package. That's how open source works. – jabaa Jul 26 '22 at 14:25
