Ruby on Rails Gems SQLite errors

Question

When I create a Rails app I am getting some errors and I have no idea what they mean or how to fix them. Instead of explaining I am going to output what is happening, I think this might be the best approach to getting help with this:

sqlite3.h is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).

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

Results logged to /home/j3/.rvm/gems/ruby-1.9.2-p290/gems/sqlite3-1.3.5/ext/sqlite3/gem_make.out

An error occured while installing sqlite3 (1.3.5), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.5'` succeeds before bundling.

转到您的gemfile并将以下代码粘贴到gems的导入列表中。

gem 'sqlite3', '< 1.4'
