Solution 1

Edit you package.json like below:

• Windows:

    "scripts": {
        "start": "react-scripts start",
        "build": "set \"GENERATE_SOURCEMAP=false\" &&  react-scripts build",
        "test": "react-scripts test",
        "eject": "react-scripts eject"
      },

• Linux:

    "scripts": {
        "start": "react-scripts start",
        "build": "GENERATE_SOURCEMAP=false react-scripts build",
        "test": "react-scripts test",
        "eject": "react-scripts eject"
      },

Solution 2 (Recommended)

This solution is not operating system dependent and works on both Linux and Windows. Just create a file called .env and add the following line to it:

GENERATE_SOURCEMAP=false
