Question

我正在使用Electron + React + Webpack模式为Mac OS构建桌面应用程序。当我将Electron桌面应用程序构建为生产版本时，我想在安装文件（Test.app和Test.dmg）中插入一些图像文件，并使用如下图像：

let Logo = process.resourcesPath + '/logo.png';

class Loading extends Component {
  render() {
    return (
        <div className={styles.container}>
          <img className={styles.logo} src={Logo} />
          ...
       </div>
      );
  }
}

但是这个应用程序无法获取图像，因为当我运行'npm run package'命令并为Mac构建Test.app时，logo.png文件未包含在Test.app/Content/Resources/目录中OS。

此处的问题如下：

GET file：///Applications/Test.app/Contents/Resources/logo.png 净:: ERR_FILE_NOT_FOUND

我想在Mac OS的Test.app包中插入此图像文件。

请帮助我如何将一些图像文件插入到Mac OS桌面应用程序的Test.app包中。

安装电子应用程序后，它将所有源代码和资源文件放入 .asar 包中。因此，要插入任何图像，您必须在应用程序外部使用目录。通常，此目录可以是“文档”文件夹。

//alt_title[text() = "HP"]/parent::title

使用 tempFolder 目录保存图像。
