問題描述

這與我的第一個問題有關.我更新了所有代碼.在我的 bot.js 中是:

This is related to my first question. I updated all of my codes. In my bot.js is:

require('dotenv').config();

let ver = process.env.DISCORD_BOT;

client.once('ready', async () => {
  if (ver === 'production') {
    client.user.setActivity(`in code land`, { type: 'PLAYING' });
  } else {
    client.user.setActivity(`over ${client.guilds.cache.size} server(s)`, {
      type: 'WATCHING',
      status: 'IDLE',
    });
  }
  console.log(`Logged in as ${client.user.tag}!`);
  console.log(`the prefix is ` + prefix);
});

過程文件:

worker: node bot.js

package.json:

 "scripts": {
    "start": "node .",
    "test": "echo "Error: no test specified" && exit 1",
    "production": "NODE_ENV=production&&npm start",
    "development": "set NODE_ENV=development&&npm start"
  }

.env:

DISCORD_BOT= TOKEN

當我檢查 Heroku 應用程序日志時，拋出的錯誤如下:

When I checked the Heroku application logs here's the error thrown:

2021-12-22T03:13:05.436081+00:00 app[worker.1]: 代理??= new https.Agent({ ...this.client.options.http.agent, keepAlive:真 });

2021-12-22T03:13:05.436082+00:00 app[worker.1]: SyntaxError: Unexpected token '??='

我嘗試搜索 SyntaxError: Unexpected token '??='" 并且每個結果都建議將 node.js 更新到 v16-17 但我已經在使用最新版本的 Discord.js 和 Node.js.

I've tried to search for the "SyntaxError: Unexpected token '??='" and every single result is suggesting to update node.js to v16-17 but I'm already using the latest version of both Discord.js and Node.js.

推薦答案

錯誤來自 discord.js，因為您使用的是舊版本的 Node.js.邏輯空賦值運算符 (??=) 僅 在節點 v15+ 中可用.

The error is coming from discord.js and it's because you're using an older version of Node.js. The logical nullish assignment operator (??=) is only available in node v15+.

您可能認為您使用的是最新版本的 Node.js，但 Heroku 表示 如果引擎中未指定 Node 版本，將使用 14.x 版本".你可以在 package.json 文件中添加一個 engines 屬性來指定你需要的版本.由于 discord.js v13 需要 node.js v16.6+，您可以添加以下內容:

You might think that you're using the latest version of Node.js, but Heroku says that "if a Node version isn't specified in the engine, the 14.x release will be used". You can add an engines prop to your package.json file to specify the version you need. As discord.js v13 requires node.js v16.6+, you can add the following:

  "engines": {
    "node": "16.6"
  }

或者請求最新的 v16，添加這個:

Or to request the latest v16, add this:

  "engines": {
    "node": "16.x"
  }
