Error installing create-react-app with npm

Question

When I try to install create-react-app (or nodemon) globally or even within a project, I get the following error. However, I can install other packages perfectly fine both globally and locally. I think it has something to do with the fact that both create-react-app and nodemon are run from the terminal rather than used within a project's code.

I have already tried reinstalling nodejs and opening the terminal as administrator, but that did not work.

$ npm i -D nodemon

UPDATE: When I ran npm cache clean --force, I got the following error

$ npm cache clean --force

For create react app try `npx create-react-app appname`, have you tried including `sudo` in front of the terminal commands? — Dmitriy, Dec 22 '18 at 14:52
I get the same error using npx. I am on Windows 10, so I can't sudo, but I have tried to run as admin which had no result. — Shivang Patel, Dec 22 '18 at 14:57
Below the error, it also said: Install for create-react-app@latest failed with code 4294963202 — Shivang Patel, Dec 22 '18 at 14:59
@ShivangPatel, posted my solution below which worked for me. — Sikandar, Nov 29 '19 at 12:54

I got an error when running this command. Check my question for more details (I updated it). – Shivang Patel Dec 22 '18 at 13:58
@ShivangPatel delete the npm-cache found in this path: `C:\Users\Shivang\AppData\Roaming\npm-cache` and try again. This is definitely cache related issue – SanSolo Dec 22 '18 at 14:04
For some reason, I can't delete the folder. I tried right clicking and then clicking delete but that didn't work. I even tried dragging to the recycling bin, but that didn't work either. – Shivang Patel Dec 22 '18 at 14:15
@ShivangPatel then may be some virus infection or admin permission issues. Try again after restarting – SanSolo Dec 22 '18 at 14:16
I restarted and ran as admin, but it didn't make a difference. I am going to run a virus scanner right now. – Shivang Patel Dec 22 '18 at 14:24
I ran Avast and Malware-bytes but they didn't find any viruses. Do you have any other suggestions? – Shivang Patel Dec 22 '18 at 14:43
@ShivangPatel sorry nothing else. Your solution involves that npm-cache folder – SanSolo Dec 22 '18 at 14:43

Did you try to execute the command as administrator?

I was facing the same issue. Found a solution for the same.

Go to C:\Users\%UserName%\AppData\Roaming\npm-cache
Delete all items present there
Some files inside 1 or more folders you may not be able to delete, then just rename them to some random name.
Now retry npm install. It should work

Try running these commands.

npm cache clean --force

And then

sudo npm install -g create-react-app

This should work.

Use npx command instead of npm

Like this, First Mkdir appName mkdir appName Secondly Cd into the app cd appName

Thirdly run npx npx create-react-app ./

This how to run npx in react 18

Lol i just took the two previous answers and put them together. So the solution is:

npm cache clean --force (-g if first try doesnt work after npx). then just use npx instead of npm.
