  When I run npm install on a fresh git clone, I get the following peerDependencies error.

npm ERR! Windows_NT 6.3.9600
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install"

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem
  Follow the Quick start guide from README.md. The error will show up in the console after calling npm install.
• What is the expected behavior?
  No EPEERINVALID error message.
• What is the motivation / use case for changing the behavior?
  Getting started process shouldn't lead to errors.
• Please tell us about your environment:
  Windows 8.1
  node v4.4.2
  npm v2.15.0
• Angular version: 2.0.0-beta.14
• Browser: [not applicable]
• Other information
  I seem to have fixed it by switching from "rxjs": "5.0.0-beta.4" to "rxjs": "5.0.0-beta.2".

if yu update to npm 3 via npm install -g npm@3 then you should be ok. I can also fix it for npm 2 users.

@gdi2290 Thanks for the info. I upgraded to npm 3 (v3.8.7) via npm-windows-upgrade (it seems to be a special package for this purpose) and ran npm install again (after clearing the node_modules folder and the npm cache). I don't get an error now and the demo project seems to work, but I still get a warning:
UNMET PEER DEPENDENCY [email protected]
and
npm WARN [email protected] requires a peer of [email protected] but none was installed.

I would suggest to either update the guide, so people will know, that they need npm version >= 3 or update the dependencies in package.json as proposed (when that's the correct fix).

Fixed by a37c92b and 1205e1a (downgrade rxjs). Closing. 🍺 👍
