16.04 - Why I obtain these error messages when I try to install gem bundler on Ubuntu? (Could not create Makefile) - Ask Ubuntu

i not ruby developer , finding many difficult install redmine (that developed in ruby) on ububuntu 16.04 server.

i following official tutorial: http://www.redmine.org/projects/redmine/wiki/howto_install_redmine_on_ubuntu_step_by_step

it seems simple finding many difficult when "ensure bundler gem installed".

i not sure bundler gem have installed. have understand (correct me if doing wrong assertion) gem packages excutable ruby application (something jar file in java).

so, problem when perform statment in bash console:

sudo gem update 

i obtain many error messages this:

in these error messages have check /var/lib/gems/2.3.0/extensions/x86_64-linux/2.3.0/sqlite3-1.3.12/mkmf.log file content, content (that maybe give additional information understand probem):

so, reading previous log file, seems problem related to:

  fatal error: sqlite3.h: no such file or directory 

it seems c header file missing don't know why.

why have problem? missing? how can try fix issue?

tnx

you're missing sqlite program/libs. install using command given in logs

sudo apt-get update sudo apt-get install sqlite3 libsqlite3-dev
