i error:

/usr/bin/ruby2.1 extconf.rb mkmf.rb can't find header files ruby @ /usr/lib/ruby/include/ruby.h

extconf failed, exit code 1

gem files remain installed in /var/lib/gems/2.1.0/gems/sqlite3-1.3.13 inspection. results logged /var/lib/gems/2.1.0/extensions/arm-linux/2.1.0/sqlite3-1.3.13/gem_make.out installed bundler-1.15.4 parsing documentation bundler-1.15.4 done installing documentation bundler after 73 seconds 2 gems installed

the system missing ruby dev files. if using debian

sudo apt-get install ruby-dev

should work.

install ruby-dev using package managers. (package name may differ across different linux distros)
