【问题描述】：

我目前的代码不起作用。

  const args2 = message.content.split(" ")
 
  if (message.content.startsWith("d!eval")) {
    if(!message.author.id == "749092490556080158") return;
    try {
      const code = args2.join(" ");
      let evaled = eval(code);
      
 
      if (!typeof evaled == "string")
        evaled = require("util").inspect(evaled);
 
      message.channel.send(clean(evaled), {code:"xl"});
    } catch (err) {
    console.log(err)
    message.channel.send(err)
    }
  }
  });

相反，它返回错误：

我不知道如何解决它，如果有人可以留下 github 链接或类似的东西，将不胜感激！

这对我有用！

 if (message.content.startsWith("d!eval")) {
    if(!message.author.id == "749092490556080158") return;
    var result = message.content.split(" ").slice(1).join(" ")
        let evaled = eval(result);
        console.log(result)
        }

【解决方案2】：

您忘记定义函数 clean()。据我所知，使用它会正常工作

const args2 = message.content.split(" ")
 
  if (message.content.startsWith("d!eval")) {
    if(!message.author.id == "749092490556080158") return;
    try {
      const code = args2.join(" ");
      let evaled = eval(code);
      
 
      if (!typeof evaled == "string") evaled = require("util").inspect(evaled);
      message.channel.send(evaled, {code:"xl"});
    } catch (err) {
    console.log(err)
    message.channel.send(err)
    }
  }
  });
