错误代码：“MODULE_NOT_FOUND”试图在 Heroku 上部署机器人

Question

我正在尝试在 Heroku 上部署我的 Twitter Bot，但我做不到。

我已经在 Heroku Vars 中配置了 Twitter 密钥，package.json 没问题...我在 Google 中进行了调查，但找不到解决方案。我不知道我做错了什么。有人可以帮帮我吗？

错误是这样的：

Answer 1

抱歉，我找到了，所以我会尝试回答问题：

终于路由问题。在 Heroku 上部署机器人时，程序无法访问 config.js 文件或 bot.js。

Config.js 不想将其公开，因为其中包含 Twitter 密钥。最后我将其公开，但参考 Config.env 文件，这是实际读取 Twitter 密钥的位置（存储在 Heroku Vars 中），我通过 [dotenv] 模块访问该文件（https://www .npmjs .com/package/dotenv)，如下所示：

Config.js：

const path = require('path')
const dotenv = require('dotenv')
require('dotenv').config();
// Load config
dotenv.config({ path: './config/config.env' })

module.exports = {
    consumer_key : process.env.API_KEY,
    consumer_secret : process.env.API_SECRET_KEY,
    access_token : process.env.ACCESS_TOKEN,
    access_token_secret : process.env.ACCESS_TOKEN_SECRET
};

推送完成后，就完美运行了。

如果将来有人发生类似的事情，希望这会有所帮助:)
