Or am I doing something wrong?

What version of node/npm are you using?

[acidjunk]

node == v7.7.4
npm == 4.1.2

[jpsc]

Yes. That was never tested with those versions. It has been 2 years since this was last updated. I can try looking into that but the best way is to use an older version of node.

[acidjunk]

Can you suggest a version?

v5.12.0 works for me but I would strongly recommend not to use this. It has not been maintained for a while. You can look into demo-viewer for a possible alternative.

I had a similar issue. It is due to a deprecation of a function used at socket.io (See https://superuser.com/a/1158316/561878 and LearnBoost/websocket.io#55)

Installing a newer karma version (which is the library that import socket.io) solved the problem for me.
