'npm start run problem with react-app-rewire

I am trying to use mobx in a reactjs project. I have installed these packages using yarn add command:

yarn add mobx mobx-react react-app-rewired react-app-rewire-mobx

after that I have replaced react-scripts with react-app-rewired in package.json file. 

"dependencies": {
    "mobx": "^5.13.0",
    "mobx-react": "^6.1.3",
    "react": "^16.9.0",
    "react-app-rewire-mobx": "^1.0.9",
    "react-app-rewired": "^2.1.3",
    "react-dom": "^16.9.0",
    "react-scripts": "3.1.1"
},
"scripts": {
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test",
    "eject": "react-app-rewired eject"
},

But when I type 'npm start' command in terminal it gives me error and nothing starts. Here the error lines:

 D:\Projects\react\todo>npm start

 > [email protected] start D:\Projects\react\todo
 > react-app-rewired start

I am new to reactjs and not familiar with these errors and their solutions. Would you help me?

Configuring react-app-rewired Installing the package First, let's install the package with the command below.

yarn add react-app-rewired -D

Configuring the scripts The operation of react-app-rewired is quite simple. To make it work in our project, just access our package.json and change the scripts (except for EJECT), replacing react-scripts with react-app-rewired, as shown below:

//package.json
  "scripts": {
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test",
    "eject": "react-scripts eject"
  },
