Easyrtc gives socket.io.js file issue for the html of the site - node.js

Question

The same question is available on easyrtc forum
https://easyrtc.com/forums/viewthread/167/
I was trying to implement the demo provided here : https://demo.easyrtc.com/demos/demo_audio_video_simple.html
Following steps as given in the below link
https://easyrtc.com/docs/guides/easyrtc_server_install.php
—-
Install Node.js
curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs
—-
I am at logged in as root user
root#pbx:/var/www/html#
I did not get any erorr while running above commands
After running the above commands , I went to the second step
——-
2. Create folder hold the EasyRTC application
ex: sudo mkdir /var/nodes
ex: sudo mkdir /var/nodes/easyrtc
—-
I created a folder /var/nodes/easyrtc as given in example
Should I create instead on /var/www/html (where my domain is pointed to)
—-
3. Security Considerations (not going into specifics)
Create user for node.js (or use existing web user)
chown the nodes folder to be owned by this user
ensure the node is run as that user.
—-
Skipping above step since I am already logged in as root.
Please point out how I could verify the three things mentioned above.
———
Download files from the server_example(https://github.com/priologic/easyrtc/tree/master/server_example) folder into your EasyRTC application folder.
OR download and extract this .zip
—-
Does ‘EasyRTC application folder’ mentioned above indicate /var/nodes/easyrtc ?
https://github.com/priologic/easyrtc/tree/master/server_example
root#PBXRecptionist2:/var/nodes/easyrtc# ls
easyrtc-master master.zip package.json README.md server.js static
After downloading the files I get the above in the easyrtc folder
—
Change to the easyrtc folder and then install node modules locally
cd /var/nodes/easyrtc
sudo npm install
—
following the other instructuion
It added node_modules folder with modules as given below
root#PBXRecptionist2:/var/nodes/easyrtc/node_modules# ls
easyrtc express socket.io
—-
Running EasyRTC Server
From Console
Open your console on the server.
In Windows you can use the provided Node.js console program located in the Start Menu.
Navigate to your EasyRTC application folder
Run the server using the node command.
node server.js
—
What does “Open your console on the server.
” mean?
I am logged in via ssh
should I type command “node ” which opens a node console ??
Does “Navigate to your EasyRTC application folder” this mean moving to /var/nodes/easyrtc ?
When I do this “Run the server using the node command.” ,
node.js on /var/nodes/easyrtc
I get the following error
root#PBXRecptionist2:/var/nodes/easyrtc# node server.js
module.js:340
throw err;
^

and if I do it
root#PBXRecptionist2:/var/nodes/easyrtc# node
node server.js
...
I dont get anything
can anybody point where I am going wrong
Also I get an error that” Your HTML has not included the socket.io.js library”
I am unsure how can I locate the socket.io.js library
My index.html for which I get the above error is
