Node.js Oracle数据库连接错误：错误：类型错误：Oracle.getconnection不是函数

获取错误

错误：TypeError:oracle.getconnection不是函数

显示：

看起来你把getconnection错拼成了小写的c

export class DBConnect {

  databaseConnection() {
    let connection;
    const oracle = require('oracledb');
    try {
    connection = oracle.getconnection({
      user : 'user',
      password : 'password',
      connectString : 'connectString'
    });
    connection.execute('Select * from table',
    function (err, result) {
     console.log(result.rows);
    });
   } catch 
    (err) {
     console.log('Error :' + err);`enter code here`
    }
  }

}

 connection = await oracledb.getConnection(dbConfig);
