Попытка получить доступ к электрону изнутри vue, и он выдает ошибку TypeError.

TypeError: fs.existsSync is not a function
  at getElectronPath (index.js?bdb9:7)
  at Object.eval (index.js?bdb9:18)
  at eval (index.js:20)

Поиск в Google не сильно помог. Я нашел один пост, в котором предлагалось бы добавить следующее к vue .config. js. Это не сработало для меня.

module.exports = {
  pluginOptions: {
    electronBuilder: {
      nodeIntegration: true
    }
  }
}

Я использую следующие

  • macOS Catalina 10.15.3
  • Vue 3.0
  • vue -cli-plugin-электронный-строитель
  • узел v13.3.0
