. npm start
does not work and throws this error message in the terminal
> test@0.1.0 start C:\Users\franc\Desktop\test

Does anybody know how to solve it?
回答1:
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.

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