Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

of V8 found on your system and *not* the one that is bundled with
the libv8 rubygem.
However, your system version of v8 could not be located.
Please make sure your system version of v8 that is compatible
with 18.104.22.168 installed. You may need to use the
--with-v8-dir option if it is installed in a non-standard location

To see why this extension failed to compile, please check the mkmf.log which can be found here:
extconf failed, exit code 1
Gem files will remain installed in /Users/koichi/.rbenv/versions/2.3.4/lib/ruby/gems/2.3.0/gems/therubyracer-0.12.3 for inspection.

Versions of the libv8 gem track the version of v8 itself, adding its own point release after the main v8 version. So libv8 126.96.36.199 and 188.8.131.52 both correspond to v8 version 3.11.8. Another way to think about it would be that 184.108.40.206 is the 14th release of the libv8 rubygem based on v8 version 3.11.8
