Answer 2

It sets up your development environment so that you can use the latest JavaScript features, provides a nice developer experience, and optimizes your app for production.

You’ll need to have Node >= 8.10 and npm >= 5.6 on your machine. To create a project, run:

npx create-react-app my-app

cd my-app

npm start

Note: npx on the first line is not a typo — it’s a package runner tool that comes with npm 5.2+.

Create react app provides more information regarding this.

It may be the problem of cache also, so can also try:

npm cache clean --force

Edit 1: This may be due to slow internet speed, Please check the internet and try again.

Answer 3

I had the same problem, and I solved it by:
1. update the npm version (npm install npm@latest -g)
2. clear the cache (npm cache clean --force)
3. create the react project (npx create-react-app todo)
(create-react-app was already installed)

Answer 4

Make sure you are not running any antivirus, stop/pause all antivirus or protection software.

You can also try

use create-react-app projectname --save
or create-react-app projectname --save-exact and start again

OR

as the error suggests, you should use a newer version of node. You are using 8.9.4, you should probably use 8.12.0 LTS.

Answer 5

The problem on my machine was caused by yarn. I am windows 10 and after uninstalling yarn using npm uninstall -g yarn, my script run correctly. So

1. Open terminal and type: npm uninstall -g yarn
2. Once done, close terminal and open new one
3. type create-react-app (app name) and this should create your app :)

Please note that the above steps assume that you already have node and react-cli installed on your machine.

Answer 6

Please try this:

npm cache clean --force
