老师好
db.js代码如下。
这样写会报错：Client does not support authentication protocol requested by server;
consider upgrading MySQL client

可是把module.exports改成 module.exports=MYSQL_CONFIG就不会报错。这是为什么啊

const env=process.env.NODE_ENV

let MYSQL_CONFIG
let REDIS_CONFIG

if(env==="dev"){
    MYSQL_CONFIG={
        host:"localhost",
        user:"root",
        password:"lwjkkkbbb1997",
        port:"3306",
        database:"myblog"
    }
    REDIS_CONFIG={
        port:"6379",
        host:"127.0.0.1"
    }
}
if(env==="production"){
    MYSQL_CONFIG={
        host:"localhost",
        user:"root",
        password:"lwjkkkbbb1997",
        port:"3306",
        database:"myblog"
    }
    REDIS_CONFIG={
        port:"6379",
        host:"127.0.0.1"
    }
}

module.exports={
    MYSQL_CONFIG,
    REDIS_CONFIG
}
