获取 Node 项目上的 `tsc` 导入依赖

Question

我正在使用 Node 和 Typescript 创建一个小型不和谐机器人。

当前的代码非常简单：

import * as Discord from "discord.js";
const config = require("./config.json");

const client = new Discord.Client();

client.on("ready", () => {
  if (client.user) {
    console.log(`Logged in as ${client.user.tag}!`);
  } else {
    console.log(`Ready without client.user`);
  }
});

client.on("message", (msg: any) => {
  if (msg.content === "ping") {
    msg.reply("Pong!");
  }
});

client.login(config.BOT_TOKEN);

bot.js ，我试图让它构建一个要上传到主机的bot.js文件。

到目前为止，它一直失败，因为结果只是：

var __createBinding = (this && this.__createBinding) || (Object.create ? (function(o, m, k, k2) {
    if (k2 === undefined) k2 = k;
    Object.defineProperty(o, k2, { enumerable: true, get: function() { return m[k]; } });
}) : (function(o, m, k, k2) {
    if (k2 === undefined) k2 = k;
    o[k2] = m[k];
}));
var __setModuleDefault = (this && this.__setModuleDefault) || (Object.create ? (function(o, v) {
    Object.defineProperty(o, "default", { enumerable: true, value: v });
}) : function(o, v) {
    o["default"] = v;
});
var __importStar = (this && this.__importStar) || function (mod) {
    if (mod && mod.__esModule) return mod;
    var result = {};
    if (mod != null) for (var k in mod) if (k !== "default" && Object.prototype.hasOwnProperty.call(mod, k)) __createBinding(result, mod, k);
    __setModuleDefault(result, mod);
    return result;
};
define(["require", "exports", "discord.js"], function (require, exports, Discord) {
    "use strict";
    Object.defineProperty(exports, "__esModule", { value: true });
    Discord = __importStar(Discord);
    var config = require("./config.json");
    var client = new Discord.Client();
    client.on("ready", function () {
        if (client.user) {
            console.log("Logged in as " + client.user.tag + "!");
        }
        else {
            console.log("Ready without client.user");
        }
    });
    client.on("message", function (msg) {
        if (msg.content === "ping") {
            msg.reply("Pong!");
        }
    });
    client.login(config.BOT_TOKEN);
});
//# sourceMappingURL=index.js.map

我一直在调整设置，试图让它按预期构建，但到目前为止没有结果。

我的tsconfig.json如下：

在您的编译器选项中，您有"module": "amd" 。 这是错误的。

Discord 使用了一个使用普通 js 的节点 api，因此将其更改为： "module": "commonjs" 。
