Add module to meteor - “Cannot find module 'extend'”

I have just start learn Meteor and came with a problem. That’s probably a noob question, but still I didn’t succeed to solve the problem after deep google searching.

Whenever I want to add a module, I just can’t, I am getting this:

C:\Users\Remy\Desktop\Meteor\leaderboard>meteor add accounts-password
=> Errors while adding packages:

While downloading npm-bcrypt@0.7.8_2…:
error: Cannot find module 'extend’
This goes for every module I tried to add:

C:\Users\Remy\Desktop\Meteor\leaderboard>meteor add aldeed:collection2
=> Errors while adding packages:

While downloading aldeed:collection2@2.8.0…:
error: Cannot find module ‘extend’

While downloading aldeed:collection2-core@1.0.0…:
error: Cannot find module ‘extend’

While downloading aldeed:schema-deny@1.0.1…:
error: Cannot find module ‘extend’

While downloading aldeed:schema-index@1.0.1…:
error: Cannot find module ‘extend’

While downloading aldeed:simple-schema@1.5.3…:
error: Cannot find module ‘extend’

While downloading mdg:validation-error@0.2.0…:
error: Cannot find module ‘extend’

While downloading raix:eventemitter@0.1.3…:
error: Cannot find module 'extend’
I’m using windows 10, maybe that’s the problem? Thanks in advance.

This ^^ is a stackoverflow question I have post few days ago but nobody has answered :frowning:

Alright, there is another day without anycomment :-\
Shall I post bug on github?

Did you create your leaderboard from the provided example? So, did you do this?

cd C:\Users\Remy\Desktop\Meteor
meteor create leaderboard --example leaderboard
cd leaderboard
meteor add accounts-password
