Answer 1

似乎此行未正确读取文件：

let hp = require("./hp.json");

检查并确保它在您指定的位置。 require语句应该对其进行解析。

Answer 2

请替换这段代码：

if(!hp[message.author.id]){

  hp[message.author.id] = {
    hp: 0
  };
}

let hpAmt = Math.floor(Math.random() * 1) + 1;
let basepAmt = Math.floor(Math.random() * 1) + 1;
console.log(`%{hpAmt} ; ${basepAmt} ; `);

if(hpAmt === basepAmt){
  hp[message.author.id] = {
    hp: hp[message.author.id].hp + hpAmt
  };
  fs.writeFile("./hp.json", JSON.stringify(hp), (err) => {
    if (err) console.log(err)
  });
}

使用：

client.on("message", async message => {

if(!hp[message.author.id]){

  // Not a problem anymore :)

  hp[message.author.id] = {
    hp: 0
  };
}

let hpAmt = Math.floor(Math.random() * 1) + 1;
let basepAmt = Math.floor(Math.random() * 1) + 1;
console.log(`%{hpAmt} ; ${basepAmt} ; `);

if(hpAmt === basepAmt){
  hp[message.author.id] = {
    hp: hp[message.author.id].hp + hpAmt
  };
  fs.writeFile("./hp.json", JSON.stringify(hp), (err) => {
    if (err) console.log(err)
  });
}
});

为什么消息未定义
