Error running npm.list

When I run npm.list from a %%node cell in a notebook I receive the following error:

CalledProcessError: Command '['npm', 'list', '-s']' returned non-zero exit status 1

Here is the out from npm list -s from the command line:

@markwatsonatx The error only happen with npm v5. As a workaround, you can try downgrading npm to v3 e.g: npm install -g npm@latest-3
