Creating a new project with npm <= 5.2

instructions.md

If you use npm 5.1 or earlier, you can't use npx. Instead, install create-react-app globally:

npm install -g create-react-app

Now you can run:

create-react-app my-app

thanks

Thank you

Could someone please help me on how to work this out for me as I had no luck for the past month. Thanks.

Re-start your computer, Windows. Use, gitbash or cmd for the commands, don´t use power shell

"npx create-react-app doesn't work for me. I get this feedback I already tried reinstalling the latest version of node using nvm-windows. This is what the path of my environment variable looks like, automatically added by nvm; If i first do "npm i -g create-react-app" before the npx command it works, but i shouldn't have to do that right?

Run

1. npm install create-react-app
2. npx create-react-app project-name.

It will probably work without the -g flag.

yeah it worked, thanks !!

Thanks @gaearon!

Thanks!

You are running create-react-app` 4.0.3, which is behind the latest release (5.0.1).

We no longer support global installation of Create React App.

Please remove any global installs with one of the following commands:

• npm uninstall -g create-react-app
• yarn global remove create-react-app
  `

Thanks a lot for this post, Its help

thankz pro!

not working with this command please guide me
npm install -g create-react-app
create-react-app my-app

I solved my own issue. I was able to find help here https://lightrun.com/answers/facebook-create-react-app-create-react-app-stuck-on-v403-cannot-create-a-new-app and fixed by running command: npx create-react-app@5.0.1 app-name

I'll leave this here in case this can help anyone else with the same issue.

Thanks @angv2852 That helps!

For everybody who had or may have a problem with installation, here is one example of a solution
