SyntaxError:意外的令牌'?在 repl.it 上用 JavaScript 制作不和谐机器人时

问题描述

我收到一个错误:

const token = this.client.token ?? this.client.accessToken;
                                 ^
SyntaxError: Unexpected token '?'

Discord Bot 代码:

Code For Discord Bot:

const Discord = require("discord.js")
const client = new Discord.Client()

client.on("ready", () => {
  console.log(`Logged in as ${client.user.tag}!`)
})

client.on("message", msg => {
  if (msg.content === "ping") {
    msg.reply("pong")
  }
})

client.login("my token here")

推荐答案

这大概和FreeCodeCamp教程有关使用 JavaScript 编写 Discord 机器人.您实际上可以使用 repl.it shell 来解决这个问题.转到 shell(控制台选项卡右侧的选项卡)并输入 npm i discord.js@12.5.3

This is probably related to the FreeCodeCamp tutorial Code a Discord Bot with JavaScript. You can actually use the repl.it shell to solve this. Go to the shell (the tab on the right of the console tab) and enter npm i discord.js@12.5.3
