Node.js Question

Error: Cannot find module './algs'

When trying to run a nodejs server I keep getting this error for a missing module './algs'. Does anyone know which module I need to install to get this to work?

Error :

$ node index
throw err;

I have tried
npm install algs
but it does not work.


I am not sure but I don't think it's about algs module or if there any module called algs.

A similar thing happened to me today. I was using event-stream with gulp and trying to concat two streams. While running the code, I saw some random module error like yours and the funny thing is I didn't even use that random module in my code. Then I looked closely and found that I am missing a comma in between two streams. I guess the module which shown missing by the error, was a dependency for event-stream (module that I have used).

I am not saying you maid mistake like me but taking a close look may help you.
