Error in “npm start” for newly created project

问题

I just created a react js project. Then I run "npm start" for run the project. this error come and I am stuck here for 1 day now. I have already have other reactJS projects. This error came for all other projects. That's why I tried it with new project. So I confirmed by creating new project. Error is not in my project.

I already tried.

Delete node_module folder then npm install
clear node cache.
Reinstall node.js
Create new project.
Reduce the version of 'react-script'
Uninstall node.js and delete all files in c drive with the name of "node"
Installing old version of node.js

Error is,

C:\Suranga\ReactJS\JMSL\my_app>npm start

> my_app@0.1.0 start C:\Suranga\ReactJS\JMSL\my_app
> react-scripts start

For archive purposes, here is the solution reported by OP.

Downgrade to react-scripts 2.1.8.

create-react-app my-app
cd my-app
npm install react-scripts@2.1.8
npm start

First make sure you are in the right application folder that was created with create-react-app. Else, trying running npm install in the folder.

Still had same problem for others. Previous solution is not success for those projects. finally I did it with following steps.

1) Install Chocolatey for windows (https://chocolatey.org/)
2) Install npm by using choco ("choco install nodejs-latest")
3) npm start
