I have been trying to create my first React App for a while now and it has been flagging me different errors.
This is the code I typed in my Hyper terminal: "npx create-react-app app".
After trying to download for some minutes it would then flag the error below:
Installing packages. This might take a couple of minutes.

I've been following a video course for full stack web development, and have gotten to the react part. The video course says that the create-react-app npm package can be used to readily and easily do an initial setup of a react app file hierarchy with all dependencies.
The method discussed in the course is to install the craete-react-app package globally using npm install -g create-react app, which I did. Then I should be creating the react app by using create-react-app my-project-name. When I launch this command, i get an output like this: Screenshot of error. In text:

The log file mentioned in the error has no extra information as far as I can see, only the same error message exactly replicated in a log file along with the preceding installation steps. Just to be sure, I've made 3 pastebins to contain the gigantic log file here: Part 1 Part 2 Part 3
Methods I've tried to resolve the issue (And a combination of some) :
The good old restart your computer!
Clearing the npm cache by usingnpm cache clear -f
Uninstalling create-react app, and reinstalling
Uninstalling create-react-app and using npx create-react-app robofriends to first install the package and then create the app folder right after
Opening my command line in administrator mode
Any help or guidance on the issue will be greatly appreciated. Thank you.
Also, it might help to mention that I am using Windows 10 64bit.
It looks like there is a problem with your path (special characters etc.). If I recreate your exact path on my drive, I fail to create a react-app as well. However, if you change your directory to another one and try again it should work!
I am trying to create a react app with

Have you tried clearing your cache using npm cache clean --force?
Check your version of npm and other
or,
Try deleting cache in the terminal as :
npm cache clean --force

if you didn't install npm in general mode, it should better you do it with this comment in the root with the command
npm install -g
, or if you did it before you need to update it with the command
npm update [-g]
There are two things that you can do that might possibily help you resolve the issue you are facing.
1.If you are on a slow internet connection you might have to increase the timeout from 30s to 60s by adding this to your .npmrc file:
timeout=6000
You can find the .npmrc file at the path:
C:\Program Files\nodejs\node_modules\npm
2. This issue might be due to npm version mismatch, you can try to install the latest npm version by typing the following command in cmd:
npm install -g npm
Hope this helps!!
Hello guys i am trying to install react into my system but from 2 days i am facing the error for several times now. At first, i have used these commands to install react app and it was working fine for me
1. npm install -g creat-react-app
2. create-react-app reactapp
but form 2 days i was facing error while choosing these options to install, therefore I visited https://create-react-app.dev/docs/getting-started/ where it was clearly stated- If you've previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app to ensure that npx always uses the latest version. Then i used the command npx create-react-app reactapp but i am facing this error. I have multiple time uninstalled nodejs and installed, also have used the command npm cache clean --forcetoo. But not working!!!!
e:\react-learn>npm uninstall -g create-react-app
removed 98 packages in 5.031s
e:\react-learn>npx create-react-app reactapp
npx: installed 98 in 39.888s

How to resolve this error???And one interesting thing you know when i copied my previous project and run npm start it is working fine. What is the issue reactapp is justing eating my nerves...
Try clearing your cache and try again.
You can run
npm cache clean --force
or
npm cache clear --force
Try using npx create-react-app client --use-npm. Sometimes some issues arise due to package managers .
