我正在使用使用 sqlite3 的 Electron 应用程序。因为我使用的是 sqlite3，所以我按照以下命令使用“electron-rebuild”重建了项目：

electron-rebuild -f -w sqlite3

然后它成功运行。

完成我的项目后，我需要使用“Electron-Packager”制作一个包。这就是为什么我在互联网的帮助下编写了一个脚本（'build.js'）。脚本如下：

const packager = require('electron-packager');
const rebuild = require('electron-rebuild');

packager({
    buildPath: __dirname,
    electronVersion: '7.1.2',
    dir: '../output',
    overwrite: true,
    asar: true,
    platform: 'win32',
    arch: 'ia32',
    icon: '/src/img/icon.ico',
    prune: true,
    out: 'project-name',
    executableName: 'project-name',
    afterCopy: [(buildPath, electronVersion, platform, arch, callback) => {
        rebuild.rebuild({ buildPath, electronVersion, arch })
            .then(() => callback())
            .catch((error) => callback(error));
    }],
})

运行脚本后，出现错误，即：


(node:7712) UnhandledPromiseRejectionWarning: Error: Unable to find all properties in parent package.json files. Missing props: ["productName","name"], "version", "author"

我正在使用的 package.json 是：

{
  "name": "project-name",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "start": "electron .",
    "rebuild": "electron-rebuild -f -w sqlite3 ",
    "package": "node build.js"
  },
  "productName": "project-name",
  "author": "Takiuddin Ahmed",
  "license": "MIT",
  "devDependencies": {
    "electron": "^7.1.2",
    "electron-packager": "^14.2.0",
    "electron-rebuild": "^1.9.0"
  },
  "dependencies": {
    "sqlite3": "^4.1.1"
  }
}

我通过重写'build.js'解决了这个问题。

我得到了电子打包器的API 文档，在那里我发现我需要在构建脚本中指定一些选项。在这些选项中，win32metadata.companyName、name 和 buildVersion 是必需的，但默认情况下，值应从“package.json”设置。“win32metadata.companyName”默认为“作者”名称，“名称”默认为“产品名称”，“buildVersion”默认为 package.json 中的“版本”。但无论如何，该程序无法从“package.json”中获取这些选项。所以，我只是在“build.js”中指定这些选项。它有效。我最终的“build.js”脚本是：


const packager = require('electron-packager');
const rebuild = require('electron-rebuild');

packager({
    name: "project-name",
    buildPath: __dirname,
    electronVersion: '7.1.2',
    version: '1.0.1',
    buildVersion: '1.0.1',
    dir: '../output',
    overwrite: true,
    asar: true,
    platform: 'win32',
    arch: 'ia32',
    icon: '/src/img/icon.ico',
    prune: true,
    appVersion: "1.0.1",
    win32metadata: {
        CompanyName: "Takiuddin Ahmed"
    },
    afterCopy: [(buildPath, electronVersion, platform, arch, callback) => {
        rebuild({ buildPath, electronVersion, arch })
            .then(() => callback())
            .catch((error) => callback(error));
    }],
});
