node.js - 在电子构建器中配置 pkg 选项脚本的最佳方法是什么？

Question

我在电子构建器的 package.json 配置中使用 pkg 选项。我有一些预安装脚本想要在安装时运行。我已经关注了electron-builder instructions为了设置脚本的位置，但 npm 似乎无法正确找到文件。

我尝试使用 chmod +x file 命令更改文件和文件夹的所有权，但错误仍然存​​在。

这是有关 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

您需要为脚本值提供 pkg-scripts 的相对路径。

package.json

"build": {
"appId": "com.audio.application",
"productName": "Audio-App",
"artifactName": "${productName}-Setup-${version}.${ext}",
"copyright": "Copyright © 2020 Audio Corp",
"mac": {
  "category": "com.audio.application",
  "target": [
    "pkg"
  ],
  "icon": "dist",
  "identity": "identity",
  "darkModeSupport": true,
  "hardenedRuntime": true,
  "gatekeeperAssess": false,
  "artifactName": "${productName}.${ext}"
},
"pkg": {
  "scripts": "../build/pkg-scripts",
  "installLocation": "/Applications",
  "background": {
    "file": "build/icon/sound.png",
    "alignment": "bottomleft"
  },
  "allowAnywhere": true,
  "allowCurrentUserHome": true,
  "allowRootDirectory": true,
  "license": "build/license.html",
  "welcome": "build/resources/welcome.txt",
  "conclusion": "build/resources/conclusion.txt",
  "isVersionChecked": true,
  "isRelocatable": false,
  "overwriteAction": "upgrade"
},
"directories": {
  "buildResources": "release",
  "output": "release"
}
},

构建目录的文件夹结构 -

preinstall.sh -
(确保您已对此文件运行 chmod +x 以使其可执行)

#!/bin/sh
echo "Executing preinstaller script for custom installer"

# Deleting App components from Application folder.
echo "Deleting Audio-Configration Logs"
logsPath=~/Library/Logs/Audio-Configration
if [ -d "$logsPath" ]
then
rm -rf ~/Library/Logs/Audio-Configration
echo "***Deleted Audio-Configration Logs Successfully***"
fi

echo "Deleting Audio-Configration Application Support"
applicationSupportPath=~/Library/Application\ Support/Audio-Configration
if [ -d "$applicationSupportPath" ]
then
rm -rf ~/Library/Application\ Support/Audio-Configration
echo "***Deleted Audio-Configration Application Support Successfully***"
fi

echo "Finished:preflight"
exit 0

以上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Application Support目录中之前的日志和应用程序相关内容
