Hi friends I am new to get on the rails & I have allready a problem in installing sqlite3-ruby. I just made my first programme :Hello world.When I execute http://localhost:3000/hello_world on my browser,then the following error comes with it. [

no such file to load -- sqlite3

RAILS_ROOT: /home/whatsup3/HelloProject

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'

… ] After that I tried:gem install sqlite3-ruby then the folloing error comes:

Looks like you are missing the development headers for ruby. These are often in a separate package from your linux distribution, often called something like ruby-dev or something along those lines.

Hello,

I have this problem before. I found answer on line. Just install sqlite3-ruby-1.2.3 instead of 1.2.4.

command is:

gem install sqlite3-ruby --version 1.2.3

hope it is helpful for you.

Thanks a lot.

I tried with gem install sqlite3-ruby --version 1.2.3 but got following error.

This way help me to fix the problem!

SQLite3: Without the -d option, rails will default to sqlite. To install SQLite3: ~$ sudo apt-get install libsqlite3-0 libsqlite3-dev ~$ sudo gem install sqlite3-ruby
