I found some similar questions, but either not exactly like it, or with no solution. So nothing seems to work for me. Any idea?

Had the same issue changed the node js version https://nodejs.org/en/download/releases/ removed npm folder from appdata and installed

Try to downgrade npm version. I had this same, on 16.14.0. I recommend nvm for changing node version. For example: nvm install 14.18.1 nvm use 14.18.1

I used npm install npm#latest -g, to update the new version of npm.
but I am not able run npm. I don't know how to fix this. I have used some of the online guideline, but It didn't worked for me.

You can add 'use strict'; in line 1 or update node.

Firebase init throwing "Use of const in strict mode" error

I installed firebase tools using
sudo npm install -g firebase-tools
and everything seemed to install fine. I already had npm and node.js installed and these are the versions:
npm: 2.11.3
node: v0.12.7
But when I try running
firebase init
from my project file, I get this error
/usr/local/lib/node_modules/firebase-tools/node_modules/request/node_modules/hawk/node_modules/boom/lib/index.js:5

How can I fix this error?
This error is due to Node.js version, you need to update to version 8 or higher.

what could be wrong
It's seem your nodejs version does not support ES2015, update your node to version 6+
you can using nvm to manage your node version
Your need Node version 6.x or higher
See documentation below
take a look here: https://github.com/angular/angular-cli/issues/4604

Error: Cannot find module './is-buffer'

I haven't found any posts that have an answer for this one. It appears to be a sourcing issue, but no matter what I try I can't seem to source it properly. I get the following error when trying to launch my application.
is-buffer is installed. I see it in my node-modules directory.
C:\MY-APP\dataService>node dataAPI.js
module.js:338
throw err;

I tried setting this in my binary file as well as my package.json. I'm able to change it in my binary file, but no matter what I'm not able to find the correct src dir.
I also tried npm install is-buffer -g to no avail. Any advice?
Unexpected token ILLEGAL
I was able to update the source to
var isBuf = require('C:\VF_PDO_APP\node_modules\is-buffer');
So now it seems to be going to the right place I think. Now however, I'm getting Unexpected token ILLEGAL.

You first must install all your project dependencies, do it on the root folder of your project:
npm install
For your problem with socket.io try to:
npm install socket.io --save
For the bson problem:
npm install bson --save
(for this one probably you will need to install python and c++)
