Interesting that the installation failed inside minimist. Maybe a network error? Can you try again?

What version of node and npm are you running?

[vikjung]

Tried multiple times same issue. Node - v4.4.5, npm - 2.15.5

I cannot reproduce on my mac, with your versions of node & npm.

@vikjung Can you try running npm install -g polymer-cli --verbose and pasting the full output here?

It looks like you have a bad package.json in your collection of global npm dependencies (~/.npm). You can run cat /Users/Vikmac/.npm/minimist/1.2.0/package/package.json on your machine to confirm that that file is empty (it most certainly shouldn't be).

Since this isn't a polymer-cli problem and is a problem with your environment (or possibly npm) I'm closing this issue. I'd recommend uninstalling/reinstalling that global package via npm and seeing if that fixes it.

Good luck!

Uninstall and reinstall of node and npm doesnt fix it. I think cached packages from previous bower install were messed up.

Executed --- npm cache clean
~/.npm is a cache that npm uses to avoid re-downloading the same package multiple times. That was having 0 byte package.json for different packages like minimist, object-assign and others

it got me further but Still was not able to run polymer then upgraded npm to 3.9.3 using
[sudo] npm install npm@latest -g

And finally have it working.
