    one way you can :

    1. go to your package.json
    2. replace "react-scripts": "..." to "react-scripts": "1.1.4",
    3. then run npm install, after that npm build

    if it didn’t work try :

    1. create a file .env at the root of the folder react folder
    2. type SKIP_PREFLIGHT_CHECK=true inside of .env file

    this command will help you in resolving this npm error.

    then try to run npm build and check it should work .

    notice : this command will permanently disable this preflight check
