I created a new react app using CRA. As soon as I started the development server, it throws the error and exits.
Starting the development server...

The react-scripts version 3.0.1 is avoiding to 'npm start'. I tried downgrading to version 2.1.8, it works fine. But I don't want to downgrade the version everytime to make my app work.
I tried following the similar case, but it didn't help.
Any one else facing the issue, please help to resolve it.
if you tried this and it didn't work for you then this maybe a react-scripts issue so to fix it try this:
remove node_modules and lock files
edit package.json so the version of react-scripts is "2.1.8"
npm install
npm start
LTK how that goes

Try to navigate to your project folder and type this commands. It helps me.
rm -rf node_modules
rm package-lock.json
rm yarn.lock
npm cache clear --force
npm install
It was giving issue for react-script version >= 3.0.0
I am able to find solution for this with my one of colleague Shivani i.e we downgraded the version of react-script from 3.4.0 to 2.1.8 by using below command nothing else changed.
Command needs to be executed from project folder or our app so that it can update package.json
https://www.npmjs.com/package/react-scripts/v/2.1.8
npm i react-scripts#2.1.8
After creating the app in vscode, I am unable to load the server port 3000. I am getting below exception
"app#0.1.0 start D:\React\app

then npm start
I am installing a create-react-app.
I have already managed to do it few weeks ago, but this time it doesn't work. It throws an error when I do the command 'npm start'.
I followed the tutorial on reactjs.org.
I have uninstalled and reinstalled latest version of nodejs (v10.15.3). My version of npm is : 6.9.0.
Any clue to help to solve this issue? Thanks

Try downgrading your react-scripts dependency to ^2.1.8 in your package.json file.
It worked for me
I am not able to execute "npm start" command. I am getting this error while running this command.
node -v : v12.0.0
npm -v : 6.9.0
I have tried to reinstall all the software.
even I have also changed the port number and try to execute the code.
what should I do?

Just delete the node_modules folder, and reinstall npm modules.
npm install
Make sure all the global & local packages that are being used in the scripts are installed, in your case it could be webpack-cli & yarn wasn't installed globally & you are trying to access it using your script.
All Export & PATH environments are setup correctly
rm -rf node_modules && npm install

I've already used npm cache clean, deleted node modules and package-lock.json and ran npm install again. I'm new to React and to programming in general so I can not really figure out what the problem is. Also, I should mention that I am a Windows user. Any help would be much appreciated.
The solution was to set the environment variable $PATH. I followed the steps mentioned here: How do I debug “Error: spawn ENOENT” on node.js?
