Sqlite 3 error

Rails
1

I have installed Ruby on Rails .
rails -v=>3.0.7
gem -v=>1.3.6
ruby -v=>ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

                         when i tried to start the server by "rails

s"
or tried to do anything it gives the error

Could not find gem ‘sqlite3 (>= 0, runtime)’ in any of the gem sources
listed in your Gemfile.
Run bundle install to install missing gems.

Please somebody help me to get rid of it…:stuck_out_tongue:

Thanks in advance

Do, what it says… run ‘bundle install’ on your app.
Or manually install sqlite3 gem

Hi,

If you r using ubuntu machine means, you can try to install the below
packages…

sudo apt-get install sqlite3 libsqlite3-dev

gem install sqlite3-ruby

This is the Solution for your problem.

Hi,

first you need to install sqlite3.
In Ubuntu: sudo apt-get install libsqlite3-dev

Second install the sqlite gem
gem install sqlite3-ruby

see here for example

I am not sure if rails 3 works with ruby 1.8.7 but I would recommend
you to switch to version 1.9.2 anyway

It worked.

Thank you very much.

          one thing left .now i can start old rail app but it gives

the
error of rake when i did “rake db:create”

rake aborted!
You have already activated rake 0.9.2, but your Gemfile requires rake
0.8.7.
Consider using bundle exec.

(See full trace by running task with --trace)

thanks

Teri you are right, ruby 1.8.7 works fine.

You can check with “gem list” which gems are installed. Probably you
have a newer version installed (0.9.2) as required in your Gemfile
(0.8.7).
So try running “bundle exec rake” instead of just rake.
See here for example:

I encourage you to use the ruby version manager. It enables you to
switch between different gem sets really easy and you can install
different gem versions for different projects.

Rails 3 and even 3.1.0rc4 work fine with ruby 1.8.7.

Make sure the place you will eventually deploy to supports Ruby 1.9.2
before switching. I just had to downgrade to deploy to Dreamhost because
their passenger won’t work with anything but 1.8.7.
