Answer 1

I had the same issue "Install for create-react-app@latest failed with code 7" Use this. It worked for me.

npm install -g create-react-app    
npx create-react-app my-app     
cd my-app      
npm start

Answer 2

If you are unable to create the app try reinstalling nodeJS in 32-bits and try it.

Answer 3

To fix the issue, run these commands in sequence

npm init
npm install create-react-app
npx create-react-app myapp

Answer 4

I had the same problem in creating react project when I used commands from official source https://reactjs.org/docs/create-a-new-react-app.html#create-react-app

npx create-react-app my-app
cd my-app
npm start

The above commands din't work on my windows. I have Node >= 6 and npm >= 5.2 on my machine even then it is not able to open localhost:3000 then I used this commands

npm install -g create-react-app
create-react-app my-app-name
cd my-app-name
npm start

It worked perfectly fine. I learned from https://www.youtube.com/watch?v=pCgDRgmfilE

Answer 5

Clean npm cache:

npm cache clean --force

then try again

Answer 6

Sometime it happens because of slow internet speed. Try with this one.

 npx create-react-app <app name> -timeout=60000

Default timeout=30000(30sec). increase timeout, if you necessary.
