JavaScript错误，缺少``）``，但是在添加了“意外的输入结尾”之后呢？ -需要帮助

Question

你好（我对编程很陌生！）

每当我尝试在CMD中运行我的机器人时，我都会不断收到此错误消息（如下）。（向下滚动查看代码，错误和内容），我对此感到非常困惑！

我尝试通过移除;来修复它，但是那没有用，它告诉我)是意外的，但是当我移除)时它告诉我需要它！

代码块一：

// Runs on bot start
bot.on('ready', () => {

  // Now we post into the console that the  bot has been turned on.
  console.log('Bot turned on in the CMD')
});

代码块二：（删除分号）

// Runs on bot start
bot.on('ready', () => {

  // Now we post into the console that the  bot has been turned on.
  console.log('Bot turned on in the CMD')
})

代码块三：

bot.on('ready', () => {

  // Now we post into the console that the  bot has been turned on.
  console.log('Bot turned on in the CMD')
}

预期结果：机器人打开，然后在CMD中发送一条消息以达到此效果。

Answer 1

代码块1是正确的，它返回的输入意外结束，因为您必须包括一个return语句。

// Runs on bot start
bot.on('ready', () => {

  // Now we post into the console that the  bot has been turned on.
  console.log('Bot turned on in the CMD');
  return('whatever');
});
