npm install

Breakdown of the Command “rm – Rf node_modules”

  • rm: The command used to remove (delete) files or directories.
  • -r (or -R): Recursive flag. It instructs the terminal to dig inside the folder and delete all nested files and subdirectories.
  • -f: Force flag. It bypasses any confirmation prompts and ignores non-existent files.
  • node_modules: The target folder holding your local Node.js package dependencies.

If we want delete package-lock.json or yarn.lock file then we need to use either

rm -rf node_modules package-lock.json

(or)

rm -rf node_modules yarn.lock
