I'm new to codeigniter 4 and I try to simply run a python code from file in controller method: So I have following: public function runPythonScript(){ log_message('debug', 'OKKKKrun1' ); //echo shell_exec("whoami"); //by this i got: nt authority\system $scriptPath = "C:/xampp/htdocs/ci4-test/public/assets/python/welcome.py"; //$command = "echo Hello World 2>&1";//this works properly $command = escapeshellcmd("C:/Users/L/AppData/Local/Microsoft/WindowsApps/python.exe $scriptPath 2>&1");//returns empty and no log in python itself so does not exacuted at all $output = shell_exec($command); log_message('info', 'OKKKKrun2' .print_r($output,true));//this logged empty if ($output === null) { $error = error_get_last(); log_message('error', 'Error executing script: ' . print_r($error, true));//this logged empty echo "An error occurred. Check the logs."; } else { echo 'result is: '.$output; } } While the path is added to system variables and shell_exec is worked properly with inline comment as mentioned above, the welcome python code does not execute at all; and any logging does not performed there; accordingly the result of python code run is empty and I get nothing when I run code on browser other than bellow: INFO - 2025-02-05 12:41:47 --> OKKKKrun1 INFO - 2025-02-05 12:41:47 --> Python script output: INFO - 2025-02-05 12:41:47 --> Executing command: C:/Users/L/AppData/Local/Microsoft/WindowsApps/python.exe C:/xampp/htdocs/ci4-test/public/assets/python/welcome.py 2^>^&1 INFO - 2025-02-05 12:41:47 --> OKKKKrun2 ERROR - 2025-02-05 12:41:47 --> Error executing script: Here is my python code: import sys try: print("Welcome to CodeIgniter!") except Exception as e: print(f"Error: {e}", file=sys.stderr) and part in routs.php $routes->get('run-script', 'Properties\PropertiesController::runPythonScript'); Can anyone describe what the is problem and how I should resolve it?
