Can anyone help me?
I wanted to work with NextJS......but I encountered this error!

You should give directory address in the installation command ,
Try : npx create-next-app#latest . if you want to install the packages in current directory or
npx create-next-app#latest YOUR_FOLDER_NAME and packages will be installed in new folder with the given name as YOUR_FOLDER_NAME.

Try this:
npm i -g create-next-app
It will install create next app globally. To create a next app run this command, if you want to install in current folder.
npx create-next-app
Otherwise, specify the folder name like,
npx create-next-app [your app name]

This text clearly states that you gave the same name to your project in package.json as the name of this package.

Rename your project in package.json and maybe a folder itself not to confuse it with this package

You should rename your project name in package.json file and try again. install package that you want to install. All of them must be OK

npm start throwing error 'This is related to npm not being able to find a file.'

I just created a react app, it was working fine but once I restart the editor it is throwing error like this :
Poojas-MacBook-Air:newreact pooja$ npm start
npm ERR! path /Users/pooja/Desktop/projects/newreact/package.json
npm ERR! code ENOENT
npm ERR! errno -2

Please help if anyone knows about it.

Make sure you have the latest npm (npm install -g npm).
Add an exception to your antivirus to ignore the node_modules folder in your project.
rm -rf node_modules package-lock.json
npm install

Sometimes the PATH is not correct, just open the cmd and cd to the address where the package.json is and then run npm start

For me, it was because of the running Metro server. If anyone is experiencing this issue in react-native, make sure you have stopped the running Metro server instance before entering npm i <package-name>.
With yarn, I think, there's no such issue.

To resolve package.json file, go to your project folder and find package.json location folder.
Open terminal and make sure your are in correct path where package.json file located.
eg: c://projectfolder/folder1/clientapp> npm start

Can not run React App after cloning it from Github

I really need your help. I would be highly appreciated.
I clone this project : https://github.com/iearn-finance/iearn-finance,
and I want to have a front-end website like this: https://yearn.finance/.
But I can not run it locally. I have tried "npm install" and then "npm start", check package.json carefully but it still does not work and gave me this error:
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path D:\iearn-finance-develop\package.json
npm ERR! errno -4058
npm ERR! enoent ENOENT: no such file or directory, open 'D:\iearn-finance-develop\package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

1- are you sure path D:\iearn-finance-develop is correct??
isn't D:\iearn-finance ??
2-did you :
delete package-lock.json and node_modules and then npm install
3-check on your filesystem if the file exists.
try these :
npm cache clean
you should initialize package with :
npm init
then install your packages

Try cleaning the cache with npm cache clean
Then initialize with npm init
After that, install your packages.
It worked for mine.

You're trying to run the command npm start
