Running npm ls after npm update doesnt show updated version?

Question

i have done the following steps.
1- npm install

2- npm ls c - this gave me dependency tree showing a particular version of package c say 1.4.1

└─┬ a@1.4.0
  └─┬ b@0.13.0
    └── c@1.4.1 

3- npm update c --depth=100
c@1.4.8 added 1 package from 1 contributor, updated 3 packages and audited 69 packages in 2.112s found 3 low severity vulnerabilities run npm audit fix to fix them, or npm audit for details
4- npm ls c

└─┬ a@1.4.0
  └─┬ b@0.13.0
    └── c@1.4.1 

This still showing old package, but when i verified in node_modules i see version 1.4.8. What can i do to make npm ls report updated dependency tree?

Answer 1

Looks like i inadvertently left package-lock.json, after removing package-lock.json and running npm ls gave the correct dependency tree.
