’db' not defined 怎么解决？
code: `let tribe=require('tribedb'), tribe_config=tribe.config;
// 添加数据库配置:第一个参数为数据库名，第二个参数为数据库配置对象 tribe_config.db('test',{ host: '127.0.0.1', port: 3306, user: 'root', password: 'root' }); //设置默认数据库 tribe_config.default_db('test');
let tribe_pool=tribe.pool; tribe_pool.query('SELECT * from stu', { db: 'test' }, function(err, rows, fields){ console.log(err); console.log(rows); console.log(fields); });`
Error: tribe.config.db('test',{ ^
TypeError: Cannot read property 'db' of undefined
at Object.
