angular-cli: Error code 1 when installing Angular CLI

This is a bug report.

When trying to install Angular CLI, I’m getting the errors listed below.

This did not happen about 3 weeks ago when I first installed it, but it does now.

OS

OSX El Capitan

Versions

Node v5.2.0 NPM 3.3.12

How I found the error

I simply ran npm i -g --save angular-cli. There were errors about lodash being expired (because a half billion modules use an outdated lodash.) and a reference to padleft that you can see at the top of the log below. For all I know that version of lodash used the leftpad module that caused all the ruckus recently. That’s just a guess, but it’s breaking the build.
