Laravel: Fatal Python error: _Py_HashRandomization_Init: failed to get random numbers to initialize Python Python runtime state: preinitialized

Question

I can try to run Python script in Laravel. I am using composer require symfony/process for this. Actually, I don’t want to use shell_exec(). When I try to run it, an error is returned. In the command line, everything is okay. My python script is located in the public folder.

My Controller:

    use SymfonyComponentProcessProcess;
    use SymfonyComponentProcessExceptionProcessFailedException;

    public function plagiarismCheck() {
        $process = new Process(['C:/Program Files/Python39/python.exe', 'C:/Users/User/Desktop/www/abyss-hub/public/helloads.py']);
        $process->run();

        // executes after the command finishes
        if (!$process->isSuccessful()) {
            throw new ProcessFailedException($process);
        }
        return $process->getOutput(); 
    }

Python script:

print('Hello Python')

Error:

The command ""C:/Program Files/Python39/python.exe" "C:/Users/User/Desktop/www/abyss-hub/public/helloads.py"" failed. 
Exit Code: 1(General error) 
Working directory: 
C:UsersUserDesktopwwwabyss-hubpublic 
Output: ================ Error
Output: ================ Fatal 
Python error: 
_Py_HashRandomization_Init: failed to get random numbers to initialize Python 
Python runtime state: preinitialized.

Answer 1

You need to configure the process environment variables:

https://symfony.com/doc/current/components/process.html#setting-environment-variables-for-processes

$process = new Process(["python", $pathToFilePython, ...$yourArgs], env: [
  'SYSTEMROOT' => getenv('SYSTEMROOT'),
  'PATH' => getenv("PATH")
]);

$process->run();
$process->getOutput();

PATH: To recognize the "python "command.
SYSTEMROOT: OS dependencies for Python to work.

Use Symfony Process. https://symfony.com/doc/current/components/process.html
Install:

composer require symfony/process

Code:

use SymfonyComponentProcessProcess;
use SymfonyComponentProcessExceptionProcessFailedException;

$process = new Process(['python', '/path/to/your_script.py']);
$process->run();

// executes after the command finishes
if (!$process->isSuccessful()) {
    throw new ProcessFailedException($process);
}

echo $process->getOutput();
