You need to install the Windows 10 SDK component of Visual Studio, as it contains the C runtime that provides errno.h.

I’ve installed Windows 10 SDK now, and I can see errno.h is located here:
C:Program Files (x86)Windows Kits10Include10.0.15063.0ucrt
Still getting the same error

You should run luarocks install from the Developer Command Prompt for Visual Studio. You have errno.h now, but it’s not being picked up by CL because it’s not in your include path. Developer command prompt will set that up for you.

That gave me some progress. Seems I had an erroneous/half-completed installation of luafilesystem. Reinstalled lua and luarocks. Tried running luarocks install luafilesystem again but now it’s complaining about my "machine type".

It looks like it’s trying to link 32 bit libs into what is otherwise a 64 bit build of luafilesystem—not familiar enough w/ luarocks or the Microsoft toolchain to know why. You should try using the version of Lua that comes with luarocks by specifying /L to the luarocks install script. That’s what worked for me.

you probably started default MSVC command prompt that is 64-bit. look into "visual studio 2015" folder in main programs menu and find there x86 command prompt. or just start simple cmd and run of the following commands, depending on your msvc version:
(disclaimer: i know nothing about luarocks, but sure it’s a way to setup msvc x86 compilation environment which i use a lot)
