I can't install next-themes

Question

I am trying to implement the shadcn dark mode ui, but the package isn't downloading. Here is what I get in the terminal when I enter npm i next-themes:

$ npm i next-themes  

up to date, audited 1716 packages in 4s

281 packages are looking for funding      
  run `npm fund` for details

To address issues that do not require attention, run:
  npm audit fix      

To address all issues possible (including breaking changes), run:
  npm audit fix --force

Some issues need review, and may require choosing
a different dependency.

Run `npm audit` for details.

The issue is that it doesn't show inside my package.json when I install it and when I try to import it, it can't be found. I thought it was because of my next version but I updated it and it still does not work.

Answer 1

Try removing the lock file package-lock.json After that clear the npm cache with the following command: npm cache clean –force. Now try installing the package(s) again npm install next-themes
