do you have a different package management file? like a pyproject.toml or a pipfile?

Yes, I have package.json and tailwind.config.js for TailwindCSS

Procfile
web: gunicorn dsdamembership.wsgi --log-file -

I tried using railway.json and remove Procfile

{
"$schema": "https://railway.app/railway.schema.json",
"build": {
"builder": "NIXPACKS"
},
"deploy": {
"startCommand": "python manage.py migrate && python manage.py collectstatic --noinput && gunicorn dsdamembership.wsgi",
"restartPolicyType": "ON_FAILURE",
"restartPolicyMaxRetries": 10
}
}

But no lack. I always got crashed on every deployment

And now I have got this error.

It says
/bin/bash: line 1: python: command not found

please share your repo

Shared with you. Thank you for helping me even though you stated in your profile here that "I don't work for Railway". Really appreciated your help..

try using this railway.json file instead

{
  "$schema": "https://schema.up.railway.app/railway.schema.json",
  "build": {
    "builder": "NIXPACKS",
    "nixpacksPlan": {
      "providers": ["python"],
      "phases": {
        "setup": {
          "nixPkgs": ["...", "nodejs"]
        },
        "npm:install": {
          "dependsOn": ["setup"],
          "cmds": ["npm ci"]
        }
      }
    }
  },
  "deploy": {
    "startCommand": "python manage.py migrate && python manage.py collectstatic --noinput && gunicorn dsdamembership.wsgi",
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  }
}

Edit, seems the start command is getting a little messed up, please correct that when you put this into use.

I have applied this new code in railway.json and corrected the start command and redeploy it and I think it worked!.

I want to share the deploy logs

There are INFO logs, are all these fine? right?
