属性不存在于类型'；对象'；Typescript错误

我创建了config.ts文件，如下所示

export interface IDBConfig {
  username: string;
  password: string;
  database: string;
  host: string;
  dialect: string;
}

class Config {
  private DBConfig: IDBConfig;

  constructor() {
    this.DBConfig = {
      username: "",
      password: "",
      database: "",
      host: "",
      dialect: "",
    };
  }

  public getDBConfig(environment: string): Object {
    switch (environment) {
      case "local":
        this.DBConfig = {
          username: "root",
          password: "1234",
          database: "test",
          host: "127.0.0.1",
          dialect: "mysql",
        };
        break;
    }
    return this.DBConfig;
  }
}

export { Config };

我在sequelize.ts文件中导入了这个配置
'console.log（dBConfig）毫无问题地为我提供了dBConfig的对象。
但下一行给了我一个错误，即类型“Object”上不存在属性“database”。
“用户名”、“密码”、“主机”也有同样的问题

import { Sequelize } from "sequelize";
import { Config } from "./config";

class SequelizeRun {
  private sequelize: object;

  constructor() {
    this.sequelize = {};
  }

  public getSequelize() {
    const config = new Config();
    const dBConfig = config.getDBConfig("local");

    console.log(dBConfig);

    this.sequelize = new Sequelize(
      dBConfig.database,
      dBConfig.username,
      dBConfig.password,
      {
        host: dBConfig.host,
        dialect: "mysql",
        timezone: "+00:00",
        pool: {
          max: 30,
          min: 0,
          acquire: 30000,
          idle: 10000,
        },
      }
    );
  }
}

你能给我一些解决办法吗？谢谢你阅读这篇文章

public getDBConfig(environment: string): IDBConfig {
    switch (environment) {
      case "local":
        this.DBConfig = {
          username: "root",
          password: "1234",
          database: "test",
          host: "127.0.0.1",
          dialect: "mysql",
        };
        break;
    }
    return this.DBConfig;
  }

试试这个。

您声明了

getDBConfig（）

以返回

Object

。它没有

数据库

属性。
