Getting error when npm start with React application

Question

I'm having this problem whenever I create a new React folder using npx create-react-app test. npm start does not work and throws this error message in the terminal

> test@0.1.0 start C:\Users\franc\Desktop\test
> react-scripts start

Does anybody know how to solve it?

Take a look in your package.json folder test ./test/package.json You will see something like this:

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

If that is there run npm run start add the word run - also make sure you cd into the test folder after you have created the app.

The "scripts" section that you have is the same as mine. Also, I did make sure I was in the right folder, but both `npm start` and `npm run start` give me the same error. – Francesco Pecora Mar 23 '20 at 02:07
Try removing `node_modules` and than do `npm install`. – Manan Joshi Mar 23 '20 at 02:08

I solved my problem by adding C:\Windows\System32 to the PATH in my environment variables and restarting the system.
