jupyter-dashboards installation failure

[Spencer Ogden]

Hello,

I'd like to try out the jupyter-dashboard server, but I'm having trouble with the npm installation. I'm not a nodejs expert, and I haven't had any luck googling for similar issues. I know this is only loosely related to Jupyter, but as I said, I haven't found any leads through googling.

I am running `npm install -g jupyter-dashboards-server` and the issue is when trying to install the dependency "phosphor-dragdrop". During that packages install, it fails on `npm dedupe`. The specific error is:

npm ERR! Error: EACCES: permission denied, open '/root/.npm/_locks/staging-a072192f34a17023.lock.STALE'
[snip]
npm ERR! Please try running this command again as root/Administrator.

I am running this as root to try and do a global installation. Further suggestions in the error log are to make sure I have the latest versions of node and npm. I am running the latest Gentoo stable versions:

node v6.3.0
npm  v3.10.3

and I'm trying to install phosphor-dragdrop version 0.9.1.

Has anyone seen errors similar to this? Full log below.

Thanks very much,

Spencer Ogden

For future reference, this was caused by trying to install globally as root. Installation with a user account does not cause this error, but of course does not allow global installation.

"npm cache clean" may also fix the problem when installing as root (https://github.com/npm/npm/issues/7407)

However, I have hit this issue on systems before where the root users doesn't have the ability to touch a root owned file in the root home folder. :/

Bump to note: to install as the root user, pass --unsafe to npm install (see https://github.com/npm/npm/issues/1259)
