  ]
}

And then I tried to install the module with this command:

npm i side-channel

I still got an error:

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\USER-PC\AppData\Local\npm-cache\_logs\2022-10-04T15_30_26_716Z-debug-0.log

What could possibly be the problem? I ran the start command just after installing the dependencies with 'npm install' command.

Answer 1

The best solution i have found for this problem is to uninstall and reinstall react.

This will uninstall React

to make sure it's there and show dependencies run

npm ls -g --depth=0

output:

F:\Dev\NodeJS\node22

to uninstall run

npm uninstall -g create-react-app

to install run

npm install -g create-react-app  

Answer 2

You can try removing node_modules and reinstalling all modules with npm install

To show your modules as of npm 7 for windows:

Global modules: npm ls --link --global

Local modules: npm ls --link

To unistall package run

npm uninstall <module_name>

To install just run

npm install <module_name>

Answer 3

It worked now. I had to delete the yarn.lock in my project, after deleting the node_modules file, then I ran the command again: npm install
