Throws error!

[post2web]

I just installed the dashboards-server as so: sudo npm install -g jupyter-dashboards-server It gives me error when I try to use it. Here is the output:

evo projects/ : jupyter-dashboards-server --help
module.js:338
    throw err;
    ^

Here is the output I got from the npm install:

Output looks ok. We probably have a regression in the published package. Does it only fail when you pass the help flag?

[post2web]

It does fail the same way with any tag or when I execute jupyter-dashboards-server just by it self. Which is the dependency who makes it fail? I would like to install it just so I go ahead with my project.

I just tried installing on my Mac running Node v5.5.0 and npm v3.5.3 and hit no issues.

In your log output, I just noticed:

npm WARN engine jupyter-dashboards-server@0.7.0: wanted: {"node":"5.10.0"} (current: {"node":"4.1.2","npm":"2.14.4"})

We minimally support Node 5.5 and npm 3.5.3. (I think these are in the README.) You probably need to upgrade.

Everything works after update to node v6.3.1
