npm ERR! code ECONNRESET

Firstly Check your network connection and then
npm cache clean --force
npm create react-app

The problem could easily be you are being blocked to that website by your ISP's or Company's firewall/proxy. Using the above method is quicker and easier but it's also insecure as it doesnt verify you are connected to the right website. To check if you are being blocked simply go to registry.npmjs.org in your browser. You should get some text back.
Option 1
Try this:
npm config set registry http://registry.npmjs.org/
so that npm requests for http url instead of https.
and then try the same npx create-react-app my-app command.
Option 2
You may also want to check your NPM proxy settings and perhaps remove it.
npm config get proxy
npm config rm proxy
npm config rm https-proxy

create-react-app aborting with code ENOENT

Just started out with React using an online course from Udemy. For some reason my create-react-app stopped working all of a sudden and it shows this log.

I checked out similar questions on here and there were some solutions I tried. The usual answer is to delete package.json but I don't have that seeing as I'm trying to make a new React app. Here's what I've tried so far:
Originally tried npx create-react-app my_app
Then tried running npm install -g create-react-app and then create-react-app my_app.
Then tried npm cache clean --force followed by npm rebuild then step 2 again.
Then tried npm init --yes to generate a package.json file, followed by trying to make a new app again using CRA.
Tried restarting the machine
Curious thing I noticed that I'm not sure is related to the issue:
When I go to Task Manager, there are two Node.js processes running. When I try to end one, it spawns another Node.js process... I can't get rid of all Node.js processes. This is why I originally restarted the machine.
Any help is appreciated! I have no idea how to proceed... I'm even thinking of formatting my machine and starting everything from scratch. However, I'd like to know why this happens so that I can avoid it in the future.

I just solved this using the following command.
npm uninstall -g create-react-app
and then:
npm install -g create-react-app

ENOLOCK npm ERR! Error while running npm audit fix

I am trying to install GLOBALLY a package with npm from my home directory. After the install has completed, it indicates vulnerabilities. Upon trying to run npm audit fix, I obtain the following error.
npm ERR! code ENOLOCK npm ERR! audit This command requires an existing
lockfile. npm ERR! audit Try creating one first with: npm i
--package-lock-only npm ERR! audit Original error: loadVirtual requires existing shrinkwrap file
I understand that the error asks me to run npm i --package-lock-only, but in which directory should I be creating this file? Running the command without specifying a path does not work. I have also tried to create the file in the directory where the package was installed, but that has also not solved the issue. Also, why isn't this file present to start with?

npm audit fix is intended to fix vulnerabilities with the dependencies of your own project. Projects do have a package-lock.json file.
It is not intended for globally installed packages. If there are vulnerabilities with packages from others, they need to be fixed by the package maintainer in a new release. You can then update to this new release.
BTW, you should not use globally installed packages. Use npx instead.

I have been trying to install or create a react app but I kept getting this error message

I have been trying to install or create a react app but I kept getting this error message
" npm ERR! Unexpected end of JSON input while parsing near '...5VmmIPyPaAPmy1Iv3blBY'"

Go to your Command Prompt, cd into the desired folder and write:
npm i -g create-react-app
Once done, write:
npx create-react-app <project-name>
It should work perfectly.

React keeps aborting installation when I try the tutorial

I was trying to follow the tutorial on the react website today but for whatever reason it doesnt want to work for me when i run the command:
npx create-react-app my-app
`I get the following error message;

My npm version is 6.5.0 and Node is 11.6.0
Not sure what the heck is going on as when I did this on my work laptop it worked without any issues with the exact same versions of node and npm

I was fix problem when I error create-react-app

Or can you fix:
--> use git bash terminal

Just an update for everyone. It worked now. All I did was reinstall nodejs for the 4th time, nothing else. Makes 0 sense. anyways, thanks for your answers, appreciate it.

I also got a same error.
Try to run npm cache clean --force after that just run create-react-app
Definitely It will work
