Answer 1

this could be a problem due to incompatibility between the npm version and the package you try to install, which is polymer-cli. You are using extre old version of all those packages. I suggest you run an update on all packages: node, git, npm.

Updating node - original answer:

• Install n:

sudo npm install -g n

• Then run:

sudo n latest

Updating npm:

• Run:

sudo npm install -g npm

Updating git - original answer:

• Run these commands in order:

  sudo add-apt-repository ppa:git-core/ppa
  sudo apt-get update
  sudo apt-get install git
  

• Then, check the version of the installed Git:

git --version

• It's not always necessary to remove the existing Git before upgrading it, but if you run into any problems, do the following and then repeat the steps mentioned above:

sudo apt-get remove git

When you're all one with these, try npm install -g polymer-cli again and send me your result.
