Question

嗨，我想将一个create-react-app生产版本部署到Heroku服务器。现在，我已经尝试了所有方法，但是在不使用serve npm或express服务器的情况下无法找到任何方法来部署它。我对此有点陌生，因此请建议部署是否必须使用Express Server或npm服务器。现在，我正在尝试通过以下方式进行部署：-

Hi have put npm run build command and get build folder now , 
In   >  .gitignor

file .

**I have added src/*
           public/*
and removed /build.**

when i tried the process suggested by heroku.
git init
heroku create -b https://github.com/mars/create-react-app-buildpack.git
git add .

git commit -m "react-create-app on Heroku"
git push heroku master


**

    Error :- 
     Could not find a required file.

I have also gone through various tutorials and all about use server.js in your react app to server build file.

Now  I want to actually know that if i am doing right process or we could not deploy react production build on heroku.
You also can   suggest better way to deploy it to heroku.

为什么需要npm serve或Express服务器才能将create-react-app生产版本部署到heroku云服务器？
