electron-builder is not bundling the python files

问题

This is my directory structure where renderer.js is included by index.html . The python scripts visitor.py and download.py are called from renderer.js via python-shell. Once I bundle, it is not able to find the python scripts

  |_ index.html
  |_ styles.css
  |_ main.js
  |_ package.json
  |_ dist/
  |_ node_modules/
  |_ renderer.js
  |_ visitor.py
  |_ download.py

I tried putting everything in files: [...] in package.json under build > files and then ran npm run dist. I also tried copying python files to dist folder explicitly and then ran npm run dist. None are working.

/Application/test.app/Contents/Resources/app.asar/remderer.js:226 Error: python: can't open file 'visitor.py': [Error 2] No such file or directory

This is my package.json

  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "start": "electron .",

      "renderer.js",
      "styles.css",
      "visitor.py",
      "download.py"
    ],

        }
      ]
    },
    "linux": {
      "target": [
        "AppImage",
        "deb"
      ]
    },
    "win": {
      "target": "squirrel",
      "icon": "build/icon.ico"
    }
  },
  "dependencies": {
    "csv-parse": "^2.5.0",
    "electron-css": "^0.6.0",
    "npm": "^6.1.0",
    "python-shell": "^0.5.0",
  },
  "devDependencies": {
    "electron": "^2.0.3",
    "electron-builder": "^20.19.1"
  }
}

PS: This is the electron-builder I am talking about https://github.com/electron-userland/electron-builder

You need to specify them as follows:

    "extraFiles": [
        "from":"source path",
        "to":"your destination"
    ]

if you want to put those files by creating directory then use extraResources

    "extraResources": [
        "from":"source path",
        "to":"some directory name"
    ]
