Error Installing pyrealsense for RealSense R200

[tangyipeng100]

I need to use the RealSense R200, which requires the pyrealsense library. However, when I try to install pyrealsense, I encounter the following error:

What could be the cause of this error, and how can I resolve it?

Hello,

the line:

pyrealsense/rsutilwrapper.cpp(1278): fatal error C1083: Cannot open include file: 'rs.h': No such file or directory

is where I'd start.

and using the prerequisites in the readme:

Windows specifics: set the environment variable PYRS_INCLUDES to the rs.h directory location and the environment variable PYRS_LIBS to the librealsense binary location. You might also need to have stdint.h available in your path.

Hope that helps.
