Looking for package.json in all the wrong places

HALPi-Thousand

Hi, Guys -
I’m trying to run Magic Mirror on a Pi 4b. I followed the install instructions perfectly, but I keep getting this error:

pi@HALpiThousand:~ $ npm start
    npm ERR! **path /home/pi/package.json**
    npm ERR! code ENOENT
    npm ERR! errno -2
    npm ERR! syscall open
    npm ERR! enoent ENOENT: **no such file or directory, open '/home/pi/package.json'**
    npm ERR! enoent **This is related to npm not being able to find a file.**

So, it can’t find the file. I found the file. It’s in the Magic Mirror folder, right where it should be. For whatever reason, MM hasn’t thought to look there. Any idea on how to teach it geography?

Fair warning, I am somewhere on the opposite end of the programming spectrum from anyone who knows what they’re doing.

Thanks

@halpi-thousand You need to be in the MagicMirror folder to run npm start. cd ~/MagicMirror then npm start

Funny thing, after I wrote that, I deleted and reinstalled Magic Mirror, then remembered that during an earlier install, I might not have done that directory change.

So now, it may be that it’s looking in the main Pi home folder, even though I’ve installed it the right way twice or three times since then.

So, I guess the question is, how do I let it know that the file is where it should be? Is there something else I should delete from somewhere else? Something that got installed in the main home folder and is probably still there?

Also, on this last install, I got this message:

pi@HALpiThousand:~/MagicMirror $ npm install

Does this help any with that question?

I think I’ve found the cuse of the problem. it begins at the npm install part:

pi@HALpiThousand:~/MagicMirror $ npm install
npm WARN read-shrinkwrap This version of npm is compatible with **lockfileVersion@1**, but package-lock.json was generated for **lockfileVersion@2**. I'll try to do my best with it!

So, it looks like, for whatever reason, it keeps doing that, and that results in it having problems trying to use it.

So, I guess the question is, what exactly is lockfile, what’s the deal with it putting this package in V@2 instead of V@1, and how can I get it to do what it’s supposed to do with it?

@halpi-thousand do

 npm install --only=prod

playwright is a testing tool for development purposes

if you used my scripted install it would have done the same

see
https://github.com/sdetweil/MagicMirror_scripts

u may have the wrong version of npm which s causing the problem.

mm needs v16

bullseye comes w v12

my script handles the upgrade too

HALPi-Thousand

@sdetweil

I’m still running Buster; tried Bullseye, ran into issues. Decided to wait a few versions. Will your script work with Buster as well, or just Bullseye?

Thanks

sdetweil

@halpi-thousand yes, and Mac, and any linux

So, I tried using that install script, ran into a few problems.

First I should mention that I did have a successful install of Magic Mirror at one point recently. Found Mystic Mirror, which apparently includes Alexa, which I want, so I deleted Magic and went to install Mystic, but ran into a bit of trickiness, so I installed Magic (or thought I did) until I could work out what to do with Mystic. And that’s around when I started running into this npm problem. Might have skipped something somewhere or gotten somethign wrong, I really don’t recall.

—edit----
You were about to be wading through a ton of text copied from the Terminal, but I somehow managed to figure out the right thing to google, and realizing that node.js was the first thing it had problems with, found out how to get rid of it. That worked. I did the full Magic Mirror installation again, and it’s happy. Just thought I’d mention the solution here.

I’ll take a swing at using your install scripts in a bit, but for now the main problem is solved. Victory!

@halpi-thousand no need to run my script if u have it.
