Node.js 在electron builder中配置pkg选项脚本的最佳方法是什么？

我正在electron builder的package.json配置中使用pkg选项。我有一些预装脚本，我想在安装时运行。为了设置脚本的位置，我遵循了，但是npm似乎无法正确地找到文件

我曾尝试使用chmod+x file命令更改文件和文件夹的所有权，但错误仍然存在

以下是关于pkg脚本配置的代码：

"build": {
    "mac": {
      "target":[
        "pkg"
      ]
    },
    "pkg":{
      "scripts":"build/pkg-scripts"
    }
 }

我收到的错误消息是：

Error: Exit code: 1. Command failed: pkgbuild --root /Users/user/myApp/myApp-out/electron-builder/mac --component-plist /Users/user/myApp/myApp/electron-builder/com.dessci.myApp.plist --install-location /Applications --scripts /Users/user/myApp/build/build/pkg-scripts /Users/user/mtdesktop/mtdesktop-out/electron-builder/com.dessci.myApp.pkg

您不需要此行，因为它是存储脚本命令的默认目录，如果您已经定义了它，则需要在应用程序目录中的../build/pkg scripts/中创建目录名，并且此目录中只允许文件名“preinstall”和“postinstall”，否则，electron builder将在运行发布函数时出错。

您需要为脚本值提供pkg脚本的相对路径

生成目录的文件夹结构-
（位于项目的根级别）

预安装.sh-
（确保已在此文件上运行chmod+x，使其可执行）

上面的预安装脚本是为了确保用户重新安装应用程序时，需要删除以前的日志以及应用程序支持目录中与应用程序相关的内容
