In fairness, she did post tracebacks that clearly show pip version 7 is
trying to build the module from source, but fails because the compiler
isn't present. Now she erred in saying that Python is attempting to
install Visual Studio.  There's nothing in any of the tracebacks that
shows Python trying to download and install a multi-GB compiler suite.

Unless she's willing to install the stock python 3.4 from python.org,
there's very little we can do to help with what's clearly an Anaconda
packaging issue.
