Just stop your node server in "task manager", and start. After that try to install with npx or npm.

Hope it is useful.

Don't worry, I also got this error. This error comes when you try to write the command create-react-app

when you type the command npm install -g create-react-app, after running this command you should restart the command prompt or command powershell whatever you are using. After restarting command prompt now you can type create-react-app cmd.

if you're a Windows OS user open your Powershell and paste the following command on your PowerShell cmd -> set-executionpolicy remotesigned.

  • run cmd as adminstrator then
  • cd to the folder you want to create the app in it and type the following

    create-react-app myapp

    this worked for me

Simply run Power shell as administrator then execute the command:set-executionpolicy remotesigned

This error comes because Microsoft changed some PowerShell execution policies for your security.

We can create react app from mainly two places.

  1. Command Prompt - You can easily create new react project without facing any issue.
  2. Powershell terminal in Visual code - If you not disables new policies of powershell yet then you will face such problem. You need follow some steps to disable these security features.
  • Run power shell as administrator
  • Type set-executionpolicy remotesigned
  • There will be 5 options.
  • You need to type Y (for [Y] Yes) and click Enter button.
  • Now you will be able to create react app in your visual code.

Hope it will work for you.

Make sure you remove create-react-app from npm globally and use npx create-react-app {project_name} to generate a react app.

npm uninstall --global create-react-app
npx create-react-app sample

also, make sure that your npm version is after 5.2 while doing these.

I think you are using Windows, I came across the same problem and it's because of a security feature in your system.

  1. Open powershell as an administrator.
  2. Run the following command set-executionpolicy remotesigned
  3. Try again.

This worked for me.
