You have to inform heroku where to start : missing script: start. In your package.json, you should have something like this:
你必须通知 heroku 从哪里开始：missing script: start。在你的package.json，你应该有类似这样：
"scripts": {
"start": "node index.js"
}
Where index.jsis your entry point.
index.js你的切入点在哪里。
As an alternative, you can specify in Procfile:
作为替代方案，您可以指定Procfile：
web: node index.js

My silly mistake was that I was pushing the master branch to Heroku while my changes were in another branch!
我的愚蠢错误是我将 master 分支推送到 Heroku 而我的更改在另一个分支中！
Make sure that you merge your latest branch with your master branch first
确保首先将最新分支与主分支合并
> git checkout master
> git merge your-latest-branch
> git push heroku master

I also faced similar kind of errors for my node js app while publishing it to heroku.com
我的 node js 应用程序在发布到 heroku.com 时也遇到了类似的错误
First create a procfile, procfile is a simple text file but without any extension.
首先创建一个procfile，procfile是一个简单的文本文件但是没有任何扩展名。
Place only one line in procfile as of now.
现在只在 procfile 中放置一行。
web: npm start
Now create the package.json file using command
现在使用命令创建 package.json 文件
npm init
once your package.json file got created please place the start property inside scripts.
创建 package.json 文件后，请将 start 属性放在脚本中。
"scripts": {
"start": "node app.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
now commit all (procfile/package.json) pending files. and deploy app again from heroku.
现在提交所有 (procfile/package.json) 待处理文件。并从heroku再次部署应用程序。
