io.set is not a function

[qubolino]

i am following the tutorial https://experimentalavionics.com/configuring-node-js-for-efis/ to get GlassPanel running

i did install the following node packages

sudo npm install sqlite3@4.2.0
sudo npm install socket.io@4.4.1

when launching the program, pi@ems:~/labs/GlassPanel $ node webserver.js i get an error:

/home/pi/labs/GlassPanel/webserver.js:7
io.set('heartbeat timeout', 4000);
   ^

TypeError: io.set is not a function
    at Object.<anonymous> (/home/pi/labs/GlassPanel/webserver.js:7:4)

am i using the right socket.io version? did i setup my path properly?

[qubolino]

looks like the proper version is sudo npm install socket.io@2.3.0. gets mr one step further.

now i have

Error: Cannot find module 'sqlite3'
Require stack:
- /home/pi/labs/GlassPanel/webserver.js
