Why Your Dependencies Break AND How to Actually Fix Them
Ever run npm install and watched your terminal explode with errors? Here's what's actually happening — and how to fix it.
Most developers treat package managers like a slot machine: run the command, cross your fingers, pray it works. When it fails? Delete node_modules, clear the cache, restart the computer for good luck.
You'll understand:
• What dependency trees are and why installing 1 package can add hundreds
• How semantic versioning works (and what that ^ symbol actually means)
• Why version conflicts happen — visualized with simple metaphors
• What lock files do and why you MUST commit them
• How to read npm errors like a detective instead of panicking
