Uncaught ReferenceError: io is not defined

I'm having trouble debugging javascript project.

I'm trying to debug both server and client side locally at the same time.

I'm using Node, Express, and socket.io.

The main.js under the server runs OK in debug mode.

When I run the client I get an error :

" Uncaught ReferenceError: io is not defined         C:/Users/Shmulik/IdeaProjects/ch-12/public/index.html:55"

The code at this lie is:

"socket = io.connect(');"

At the beginning of the index.html file I have the code:

  "<script src="/socket.io/socket.io.js"></script>"

When I run the index.html in the browser without debugger it runs OK.

Please help

Thank's

I found how to make this line work, but I don't understand why it works perfectly without the debugger.

Instead of: "<script src="/socket.io/socket.io.js"></script>"

I wrote the full path: "<script src="C:\\Users\\Shmulik\\IdeaProjects\\node_modules\\socket.io\\node_modules\\socket.io-client\\dist\\socket.io.js"></script>"

Someone?
