Answer 1

You have not created a react application. Your first command installed the create-react-app globally.

$ npm install -g create-react-app

You then try to cd (Change Directory) into a directory react-app which does not exist with the command

$ cd react-app

What you want to do is simply run this command before the other commands

$ npx create-react-app react-app

Then you can issue the following commands

$ cd react-app
$ npm run start

Answer 2

Run the create-react-app command with the name of the application that you want to build, eg:

 $ npx create-react-app name-of-your-app

Note that you use 'npx' so that create-react-app doesn't have to be installed locally. After running that command a new directory with the same name as your app is automatically created with all of the files in it.

Also it's a good idea to test that you installed Node correctly. To test this just check the version using the following command line prompts. If it prints the version then you know you installed it correctly:

 $ node --version $ npm --version

Answer 3

You have successfully installed create-react-app , which is a popular toolchain for creating react based application.

npm start command is used to start your standard react app. But in this case, you haven't created a react app yet. That's why it's giving you an error.

So to create a react app, you have already installed create-react-app toolchain. The first step is done.

Now type npx create-react-app my-first-app in your terminal. It will take some time to create your react app.

Take note that you can call your react app anything you want (in this case its my-first-app ), but make sure that all characters of your react app name are lowercase.

Once its done creating your app, it will give you a success message. After that, you need to run cd my-first-app in your terminal.

Then you can run npm start to start your application.

Answer 4

Run all the commands with Administrator access to your Terminal/Command Prompt. I was getting the same errors until I ran all the code with Admin access.
