Well it's written right there,
Maybe the MSYS2 Devkit is missing? Or the paths in the environment variables are incorrectly configured.
Without this extension, which requires compilation of C source codes into a gem, it will not be possible to install.
In addition, it is not certain that these sources are written with the Windows platform in mind. Usually they write for POSIX systems and don't bother. If not, then you should ask the author of websocket-driver to add Windows support.

Or ...

Как вариант, стоит попробовать JRuby (работает на JVM) или работать в Linux посредством Windows WSL (Windows 10)
