Fix · Node, npm and build

ENOENT: no such file or directory, open package.json

What you may see

npm says it cannot find package.json

Most likely cause

You ran the command in a folder that is not the project, or the file is in a sub-folder.

Check first (about two minutes)

Run pwd and ls to see the folder and files.

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
ENOENT: no such file or directory, open package.json

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
You ran the command in a folder that is not the project, or the file is in a sub-folder.

DO THESE STEPS, IN THIS ORDER
1. Run pwd and ls and find the folder that contains package.json.
2. cd into that folder and run the command again.
3. If the project truly has no package.json, explain what it should contain and ask me before creating one.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- npm run dev starts from that folder.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not run npm init in the wrong folder.
- 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?
