sqlite3_1.default.database 不是构造函数

如何解决sqlite3_1.default.database 不是构造函数

我通过 yarn 安装在我的 Electron-React-Typescript-Webpack 应用程序 sqlite3 中：yarn add sqlite3@latest

并使用 yarn electron-rebuild -f -w sqlite3

重建所有内容

在 webpack.config.js 中，我输入了：

const webpack = require('webpack');
    externals: [
      {
        'sqlite3': sqlite3,}
    ],

如果在 main.ts 中，我输入：

import sqlite3 from 'sqlite3';

let db = new sqlite3.Database(
    path.join(app.getPath('userData'),'/infopiecesleveldb'),(err) => {
      if (err) {
        return console.error(err.message);
      }
      console.log('Connected to the in-memory sqlite database.');
});

我收到此错误：sqlite3_1.default.database is not a constructor

关于如何解决它的任何想法？

解决方法

与

import sqlite3 from 'sqlite3';

//let db = new sqlite3.Database(':memory:',(err) => {
let db = new sqlite3.Database(
    path.join(app.getPath('userData'),'/infopiecessql3db'),(err) => {
      if (err) {
        return console.error(err.message);
      }
      console.log('Connected to the in-memory SQlite database.');
});
db.close();

现在我收到这条消息Connected to the in-memory SQlite database
