Javascript sqlite3在电子商务中的应用

我正在尝试使用sqlite3构建一个electron应用程序。现在我正在尝试将electron builder用于sqlite3，但即使在添加了安装后依赖项之后，我仍然会出错：

My package.json：

{
  "name": "store_electron",
  "version": "1.0.0",
  "description": "trying ",
  "main": "main.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "postinstall": "install-app-deps"
  },
  "author": "armelzong@gmail.com",
  "license": "ISC",
  "dependencies": {
    "sqlite3": "^4.2.0"
  },
  "devDependencies": {
    "electron-builder": "^22.7.0",
    "electron-rebuild": "^1.11.0"
  }
}

我在尝试后遇到的错误：npm运行postinstall

> install-app-deps

  • please use as subcommand: electron-builder install-app-deps
  • electron-builder  version=22.7.0

使用“postinstall”时：“electron builder安装应用程序deps”： 我明白了：

请检查这篇文章

到目前为止，将SQLite与electron一起使用的最简单方法是使用electron builder

首先，在package.json中添加postinstall步骤

"scripts": {
   "postinstall": "electron-builder install-app-deps"
   ...
 }
"devDependencies": {
   "electron": "6.0.11",
   "electron-builder": "^21.2.0",
   ....
 }

然后安装必要的依赖项并生成：

npm install --save-dev electron-builder
npm install --save sqlite3
npm run postinstall

---

electron builder将为您的平台构建本机模块，并使用电子绑定的正确名称；然后你就可以像平常一样要求输入代码了。

我明白了⨯ 无法从已安装的节点模块计算electron版本-没有安装任何可能的electron模块请在package.json“electron”：“6.0.11”、“electron builder”：“^21.2.0”中尝试此操作，我不知道我已经共享了package.json。我的软件包中似乎没有electron。请使用“electron”更新您的设计附件：“6.0.11”，“electron builder”：“^21.2.0”，然后使用npm instal，然后再执行其他步骤。为什么版本为6.0.11和builder 21.2.0？这是否回答了您的问题？
