Create-react-app: Yarn start gives such message "error Couldn't find the binary react-scripts start"

[savitskiyevgeniy]

Describe the bug

I created an app using create-react-app, but can't start it using yarn start or npm run start because I'm getting an error "Couldn't find the binary react-scripts start" or "Failed to exec start script".

Did you try recovering your dependencies?

[binarysubstrate]

On Windows, there seems to be a problem with the path. Unless you manually add the repository to your environment path variable, npm start fails.

@savitskiyevgeniy, modify your package.json with the full relative path and see if it works:

"scripts": {
    "start": "node node_modules/react-scripts/scripts/start.js"
}

[savitskiyevgeniy]

@binarysubstrate , I tried to modify package.json as you recommended but get such error after trying to exec yarn start "Couldn't find the binary node node_modules/react-scripts/scripts/start.js".

So I tried to execute node node_modules/react-scripts/scripts/start.js and it works.

Thanks a lot!
