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

downgrade react scripts for project with these commands
npm install react-scripts#2.1.8
npm start
Create a new folder and try with this:
npx create-react-app my-app
cd my-app
npm start
You’ll need to have Node >= 8.10 and npm >= 5.6 on your machine
https://reactjs.org/docs/create-a-new-react-app.html
You can try to reinstall node in the path C:\windows\System32
or you can
Follow these steps:
npm cache clean --force
delete node_modules folder
delete package-lock.json file
npm install
I have followed bellow steps for reactjs environment setup.
Installed Node.js with version - v10.16.3
npm version - 6.14.5
npm install -g create-react-app
create-react-app my-app
cd my-app
npm start.
But when I start it using npm start. It is giving me error like events.js:174 throw er; // Unhandled 'error' event

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
error from cmd

I have tried updating the yarn and even reinstalling it
You could downgrade with help of this script and writing that on your terminal then everything should be work:
create-react-app my-app
cd my-app
npm install react-scripts#2.1.8
npm start
This would definitely work. Thanks ))
I had your same problem. I deleted the node_modules folder and reinstalled using:
npm install
After that all works fine.
I find the solution here https://gitmemory.com/issue/facebook/create-react-app/6985/491604318
Please Try After Adding C:\Windows\System32 To Environment Variable Path And Restarting Your Device .
I'm guessing that you are trying to use the create-react-app
did you use npx to set it up?
npx create-react-app joakims-app
cd joakims-app
npm start
BTW: It looks like you are running windows - don't know if this is of any help

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
