When I pack my Ionic project with @capacitor-community/electron packager (using electron-builder), I get the following error:

Unhandled Promise Rejection
Error: ENOENT: no such file or directory, open 'D:/Users/.../example/electron/dist/win-unpacked/resources/app-update.yml'

Steps to reproduce the problem:

# create generic ionic example
ionic start example tabs --type angular
cd example
npm i @capacitor-community/electron --save-dev
# required to add electron
ionic build
npx cap add @capacitor-community/electron
cd electron
# runs npm run build && electron-builder build --dir -c ./builder-effective-config.yaml
npm run electron:pack

Here is package.json of ./example/electron project:

{
  "name": "example",
  "version": "1.0.0",
  "description": "An Amazing Capacitor App",
  "author": {
    "name": "",
    "email": ""
  },

And here is electron-builder.config.json file:

{
  "appId": "com.yourdoamnin.yourapp",
  "directories": {
    "buildResources": "resources"
  },
  "files": [
    "assets/**/*",
    "build/**/*",
    "capacitor.config.*",
    "app/**/*"
  ],
  "publish": {
    "provider": "github"
  },
  "nsis": {
    "allowElevation": true,
    "oneClick": false,
    "allowToChangeInstallationDirectory": true
  },
  "win": {
    "target": "nsis",
    "icon": "assets/appIcon.ico"
  },
  "mac": {
    "category": "your.app.category.type",
    "target": "dmg"
  }
}

CodePudding user response：

So, apparently problem lies in default publish method. You need to change your electron-builder.config.json file to the following form (without the comment):

{
  "appId": "com.yourdoamnin.yourapp",
  "directories": {
    "buildResources": "resources"
  },
  "files": [
    "assets/**/*",
    "build/**/*",
    "capacitor.config.*",
    "app/**/*"
  ],
  "publish": {
    "provider": "github",
    "publishAutoUpdate": false // This is the line you need to add!
  },
  "extends":null,
  "nsis": {},
  "win": {
    "target": "nsis",
    "icon": "assets/appIcon.ico"
  }
}
