NPM packages are not updated

Recently, we are facing an issue where if there is a tgz file that we push to the repository, it works, and if we make some changes onto the tgz file locally and push it to the Nexus repository, the changes are not visible. Is there any way, that we could remove the caching and make the latest changes onto the repository?

The issue has been resolved by clearing npm caches. And once that is done, we are able to see the latest changes to the repository.
Thank you,
