我是新手编码，但目前正在学习，因为我想在我的脸书页面上创建一个聊天机器人。 Belows是我在每个.js中的脚本和我之后遇到的错误。输入heroku后，网络显示“应用程序错误 应用程序中发生错误，无法提供您的页面。如果您是应用程序所有者，请检查日志以获取详细信息。“
希望有人可以帮助我，非常感谢！

var app = express()
app.set('port', (process.env.PORT || 5000))

我已经尝试并阅读了其他人在github上提出的很多问题，但我仍然无法解决问题。我从以下网站学习了设置nodejs和heroku服务器的方法：https://chatbotsmagazine.com/have-15-minutes-create-your-own-facebook-messenger-bot-481a7db54892
我真诚地希望有人能帮我解决问题，非常感谢你！

Procfile文件名应该只是Procfile，我看到你的文件名似乎是Procfile.json，可能是它。
但是当你的package.json有启动脚本时，只需确保你有git添加所有文件并在推送到Heroku之前提交它们
答案 1 :(得分：0)
这听起来可能重复，但相信我不是。我正在做一门课程，其中 100 人（如果不是数千人）有同样的问题。如果您遇到此错误，请查看以下内容。
在你的 package.json 文件中，确保你在脚本中提到了 "start": "node app.js" 以及 "licence" 下的“engines”。这是我的 package.json 的示例代码正在工作：
{
"name": "todolist-v1",
"version": "1.0.0",
"description": "todolist",
"main": "app.js",
"scripts": {
"start": "node app.js"
},
"author": "Armaghan",
"license": "ISC",
"engines": {
"node": "14.15.3"
},
"dependencies": {
"body-parser": "^1.19.0",
"ejs": "^3.1.5",
"express": "^4.17.1",
"jquery": "^3.5.1",
"lodash": "^4.17.20a",
"mongoose": "^5.11.14",
"nodemon": "^2.0.7"
}
}
为了确保您添加了正确版本的节点，请在终端中使用此命令来显示您当前的节点版本。 node --version
将 app.listen 代码替换为以下 Heroku 应用部署代码：
let port = process.env.PORT;
if (port == null || port == "") {
port = 3000;
}
app.listen(port, function() {
console.log("Server started succesfully");
});
确保您提交了正确的 git 分支。我忘记提交一个不同的（实验性）分支，它在 package.json 文件中没有更新的更改。要检查您当前的 git 存储库分支，请使用 git branch
分支显示后，您可以使用 git checkout branchname 在分支之间切换
就我而言，我想提交 master，所以我首先使用 git branch master 进入 master，然后使用
git add .（空格后包含点）。
然后使用 git commit -m "your comment"
最后使用以下命令再次将其推送到 Heroku 服务器上。
git push heroku master
推送完成后，最好在到达互联网上的网络应用地址之前给它几分钟时间，因为这可能需要一些时间来启动和运行。
亲切的问候，
