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。我已按照电子生成器的说明设置脚本的位置，但 npm 似乎无法正确找到文件。

\n\n

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。

\n\n

这是关于 pkg 脚本配置的代码：

\n\n

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

\n\n

我收到的错误消息是：

\n\n

您需要为脚本值提供pkg-scripts 的相对路径。

\n\n

包.json

\n\n

"build": {\n"appId": "com.audio.application",\n"productName": "Audio-App",\n"artifactName": "${productName}-Setup-${version}.${ext}",\n"copyright": "Copyright \xc2\xa9 2020 Audio Corp",\n"mac": {\n  "category": "com.audio.application",\n  "target": [\n    "pkg"\n  ],\n  "icon": "dist",\n  "identity": "identity",\n  "darkModeSupport": true,\n  "hardenedRuntime": true,\n  "gatekeeperAssess": false,\n  "artifactName": "${productName}.${ext}"\n},\n"pkg": {\n  "scripts": "../build/pkg-scripts",\n  "installLocation": "/Applications",\n  "background": {\n    "file": "build/icon/sound.png",\n    "alignment": "bottomleft"\n  },\n  "allowAnywhere": true,\n  "allowCurrentUserHome": true,\n  "allowRootDirectory": true,\n  "license": "build/license.html",\n  "welcome": "build/resources/welcome.txt",\n  "conclusion": "build/resources/conclusion.txt",\n  "isVersionChecked": true,\n  "isRelocatable": false,\n  "overwriteAction": "upgrade"\n},\n"directories": {\n  "buildResources": "release",\n  "output": "release"\n}\n},\n

\n\n\n\n

构建目录的文件夹结构-\n
\n（位于项目的根级别）

\n\n

\n\n\n\n

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

\n\n

#!/bin/sh\necho "Executing preinstaller script for custom installer"\n\n# Deleting App components from Application folder.\necho "Deleting Audio-Configration Logs"\nlogsPath=~/Library/Logs/Audio-Configration\nif [ -d "$logsPath" ]\nthen\nrm -rf ~/Library/Logs/Audio-Configration\necho "***Deleted Audio-Configration Logs Successfully***"\nfi\n\necho "Deleting Audio-Configration Application Support"\napplicationSupportPath=~/Library/Application\\ Support/Audio-Configration\nif [ -d "$applicationSupportPath" ]\nthen\nrm -rf ~/Library/Application\\ Support/Audio-Configration\necho "***Deleted Audio-Configration Application Support Successfully***"\nfi\n\necho "Finished:preflight"\nexit 0\n

\n\n

上面的预安装脚本是为了确保当用户重新安装应用程序时，需要删除Application Support目录中以前的Logs和应用程序相关内容
