I'm under Windows8 and I had to install Python (3.4.3) to achieve this installation.
My E2E tests are broken after this installation. Any help would be greatly appreciated.

回答1:
There was 2 problems : 1. Python 2.7.x must be installed instead of Python 3.x, 2. An environment variable named PYTHON valued to path+python.exe must be set before running npm.
After this change the installation can continu (but is blocked here : Installation of Protractor 2.0 and MSBUILD error MSB3428)
