Newman, cannot find module 'chai'

I’m tryin to run my collections in newman, but are getting error: cannot find module 'chai’
I have been doing npm install -g chai and npm install --save chai, but are still getting the same errormessage.

They’re running without problems through the runner.

Can someone give me a helping hand?

@tosh Which version of Newman are you trying to install? Could you also mention your npm version? This can be found via npm -v.

I’m using npm version = 4.2.0 and I assume an outdated newman version = 3.4.3?

Could you try installing the latest version of newman with npm i -g newman and let me know if that results in an error? Thanks!

newman version = 3.9.3
Initiated tests from newman again, and now it worked.
