在 electron 中使用 sqlite3

Question

I'm trying to build an electron app with sqlite3.Now I'm trying to use electron builder for sqlite3 but I'm getting errors even after adding postinstall dependencies :

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"
  }
}

The error I'm getting after tryied: npm run postinstall

> install-app-deps

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

Please check this post https://bitfrit.com/how-to-use-sqlite-with-electron/

By far the easiest way to use SQLite with electron is withelectron-builder.

First, add a postinstall step in your package.json

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

and then install the necessary dependencies and build:

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

electron-builder will build the native module for your platform, with the correct name for the Electron binding; and you can then requireit in code as normal.
