npm install hangs or takes forever

What you may see

The progress bar does not move for many minutes

Most likely cause

Slow network or a very large dependency list, a stuck cache, or an install waiting for a question.

Check first (about two minutes)

Wait five minutes on a good connection before stopping.

Prompt language

You are a patient senior engineer who knows Node.js, npm and build tools and explains them to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

THE PROBLEM
npm install hangs or takes forever

THE EXACT ERROR OR WHAT I SEE
[paste the exact error here]

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
Slow network or a very large dependency list, a stuck cache, or an install waiting for a question.

DO THESE STEPS, IN THIS ORDER
1. Stop it with Ctrl+C and rerun with npm install --loglevel verbose to see where it waits.
2. Check network (see the network entry), disk space (df -h), and the npm cache health (npm cache verify).
3. If it still hangs, try npm ci with the lock file.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- npm install ends and node_modules is complete.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not interrupt it again and again.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Steps

Do not do this

Do not delete the lock file.
Do not interrupt it again and again.

Fix it npm install fails with network errors (ETIMEDOUT, ENOTFOUND)
