Note

This module needs to compile itself from C/C++ source. Under Linux, this should just work. Under Windows, you may need to install a compiler, which must (to some degree) match the Python version you’re using. If you don’t have a compiler, you will get errors relating to “query_vcvarsall”. For Python 3.4, try Microsoft Visual Studio 2010 (Visual C++ 10.0) or Visual C++ Express 2010. Under 64-bit Windows, or if you have a later version of Visual Studio, see also http://stackoverflow.com/questions/28251314; you’ll need to set the VS100COMNTOOLS environment variable.
