无法成功建立从electronic-js到sqlite3数据库的连接

编程问答 2022-06-07

问题描述

我尝试了以下操作，还创建了一个数据库

import { app,browserWindow,ipcMain } from 'electron';
const sqlite = require("sqlite3").verbose();
declare const MAIN_WINDOW_WEBPACK_ENTRY: any;

if (require('electron-squirrel-startup')) { // eslint-disable-line global-require
  app.quit();
}

const createWindow = (): void => {
  const mainWindow = new browserWindow({
    height: 600,width: 800,});

  mainWindow.loadURL(MAIN_WINDOW_WEBPACK_ENTRY);
  mainWindow.webContents.openDevTools();
};

//connection to database file
let db = new sqlite.Database('./database.sqlite',(err: any) => {
  if(err) {
    return console.error(err.message)
  }
  console.log('Connected to database')
});

app.on('ready',createWindow);

app.on('window-all-closed',() => {
  if (process.platform !== 'darwin') {
    app.quit();
  }
});

app.on('activate',() => {
  if (browserWindow.getAllWindows().length === 0) {
    createWindow();
  }
});

但是运行应用程序时，我收到以下错误消息：

App threw an error during load
Error: node-loader:
Error: dlopen(/Users/newuser/workspace/programming/desktop/numberz/.webpack/main/fff62d64630267b2e965af6812745c92.node,1): no suitable image found.  Did find:

当我尝试一种方法时，我仍然得到上面相同的方法。

let db = new sqlite.Database(':memory:',(err: any) => {
  if(err) {
    return console.error(err.message)
  }
  console.log('Connected to database')
});

我已经使用过电子重建和产后检查，但仍然无法成功连接到我的数据库。请帮助
