How to install most recent httpuv?

Question

I've downloaded the tar.gz for httpuv but can't read it properly. I need it to install shiny.

install.packages("c:/.../httpuv_1.4.5.tar.gz", repos = NULL)

produces

Warning: running command 'make -f "Makevars.win" -f "C:/PROGRA1/R/R-331.2/etc/i386/Makeconf" -f "C:/PROGRA1/R/R-331.2/share/make/winshlib.mk" CXX='$(CXX1X) $(CXX1XSTD)' CXXFLAGS='$(CXX1XFLAGS)' CXXPICFLAGS='$(CXX1XPICFLAGS)' SHLIB_LDFLAGS='$(SHLIB_CXX1XLDFLAGS)' SHLIB_LD='$(SHLIB_CXX1XLD)' SHLIB="httpuv.dll" OBJECTS="RcppExports-legacy.o RcppExports.o callback.o callbackqueue.o filedatasource-unix.o filedatasource-win.o http.o httprequest.o httpresponse.o httpuv.o md5.o set_invalid_parameter.o socket.o thread.o utils.o uvutil.o webapplication.o websockets-base.o websockets-hixie76.o websockets-hybi03.o websockets-ietf.o websockets.o"' had status 127

Generally if you want to install packages containing compiled code from source, you have to install a suitable compiler and tools. On Windows this means installing Rtools . Afterwards:

 install.packages("httpuv", type = "source")

should compile and install the most recent version. However, version 1.4.5 of httpuv is available in binary form on CRAN . So installing from source is only needed if you are using an old R version (<= 3.3).
