please stop trying to install ncd-comm !
please tidy the package.json... then remove the package-lock.json file as requested - please just re-run the commands as written
rm package-lock.json and rm -r node_modules/ then npm cache clean --force - and finally npm install
DO NOT install anything else after that... - start Node-RED - then stop - then start again.. and show us that log. We will then try to get serialport and i2c working as a next step.
I've already dis that, and I've posted the result, no help. Ok I'll do it again as you said and post here.
By the time I've googled "npm ERR! path /home/pi/.node-red/node_modules/@serialport/bindings" and I've found a thread, I was reading it an by the time I've tried to install the serialport, it did (66 packages) but nothing improved. I've also again tried to install ncd comm.
This is the actual package.json

I suppose that since ncd comm is not installed i2c doesn't work also.
There is maybe an uncompatibility with nodejs 14 and serialport?
If Yes I guess I shpould remove nodejs (how?) install manually 10.24 and rebuild node red
no - I have i2c installed with node14... but it says it as compiled against NODE_MODULE_VERSION 93. - which corresponds to node16.... are you running nvm or n or some other shell ?
no I have one shell only, if you think it's better I reboot. I haven't reboot since I' upgraded with nvm
ah you said nvm ! - we need to get rid of that .... that is the cause of most of this aggro
Trying myself to fix (uninstall and reinstall nodejs) I've read that nvm is the best solution, and I've installed it. What can I do?

then try node -v
go back into your ~/.node-red directory and redo the npm install and npm install node-red-contrib-i2c@latest

there is a slight change, node red start stucks, after one minute I've terminated with control C and launched safe mode
I'm uninstalling the node-red-contrib-i2c and reinstalling
EADDRINUSE - means the service is still running so you need to stop that first...
BUT - it still says wrong node_module version - so do a npm rebuild - and then restart again.
how can I stop it?
node-red-stop
Got ti, when I've pressed control C
So I uninstalled it, rebuilt, installed again, yes now disappeared, bu ncd comm not working

OK - so did you npm i node-red-contrib-lcd20x4-i2c ?
Do you really need ncd-comm ? - Are you using that node ?
I really don't know what it is, I was thinking it is a dependency, how can I remove it? It's hidden node.. in packajge.json there is not.
Now I install LCD.
I've checked flows, probably it was related to AD1115 module, can I remove this line.. I suppose I can
