我试图为服务器制造一个不协调的机器人，我在终端中输入“ node .”以运行该机器人，但出现此错误：

在终端中。 这是index.js文件：

const Discord = require('discord.js');
const config = require('./config.json');
const client = new Discord.Client();

client.once('ready',() => {
    console.log('Ready!');
});

client.on('message',message => {
    if (message.content === '!ping') {
        message.channel.send('Pong.');
    }
});

client.login(config.token);

这是config.json：

{
"prefix": "!","token": "7F2x4ct0AMuBeJKZUGmtIz_RZVKve-N4"
}

我意识到我没有把全部错误    哎呀
