My near term goal is to continue running some tutorials from RailsApp. I had previously had no issues running rails and writing apps and doing some older tutorials. A new one came out that used a template file for thee startup app. I needed to upgrade my ruby & rails versions for this, but it still would not work (question here: Error with RailsApps starter app for rails-devise-roles tutorial) so I went ahead and upgraded mavericks.

My question is how can I get the rails to create a new app and run ? i can't develop anything now. I don't know how ot revert to older versions of ruby (maybe one that does not use sqlite3?) [<

I have googled & stack overflow searched similar problems and none of the solutions seem to work for me so far.

Basic info: $which ruby

/Users/suzanne/.rvm/rubies/ruby-2.1.2/bin/ruby

$ruby -v

ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]

$ xcode-select --print-path

/Applications/Xcode.app/Contents/Developer

I have also opened XCode, updated libraries requested after opening. Version listed on splash page is Version 5.1.1 (5B1008)

Now I have done the following steps to test rails and get a basic new app working

mkdir myapp
cd myapp
rvm use ruby-2.1.2@myapp --ruby-version --create
gem install rails
rails new .

and at this point I get this error: 

Could not find gem 'sqlite3 (>= 0) ruby' in the gems available on this machine.

XCode is installed, gcc is installed, sqlite3 is installed.

$ whereis sqlite3 

/usr/bin/sqlite3

$bundle install

There was a change in Mavericks that means you have to install the command line tools.

Type in a terminal window

xcode-select --install

You should then be prompted to install the command line tools

Once that is done, you should be able to build your gems

Try gem install sqlite3 -- --with-sqlite3-dir=/opt/local and then run bundle install again.

If that doesn't work, I think you just need to install sqlite3. If you have Homebrew, this should work:

brew install sqlite3

  • THanks @undo. It is installed, see above, in this directory (whereis sqlite3) /usr/bin/sqlite3. I couldn't find documentation on what all the options do, the only thing I see in my /opt/ drive is X11. Just for my own learning, what is the significance of installing it in the /opt/ directory? – Shazam Sep 08 '14 at 19:47
  • I tried both of those, the gem install got the same error, adn the brew install didn't change anything. I feel like this is a path issue but for the life of me I can't sort out how to solve it. – Shazam Sep 08 '14 at 19:59
  • @Shazam I think it even needs source libraries. try ```brew install sqlite3 --build-from-source``` and then try to install the sqlite3 gem. Also if it's already installed try removing and re-installing from source again. – Saurabh Bhatia Sep 17 '14 at 09:27
  • @SaurabhBhatia, thanks for the idea..I was able to build from source, but still cannot install the gem. Still trying to search for answers. Possibly a path issue, but seems the paths are correct. I'll keep trying. – Shazam Sep 18 '14 at 04:33

Had the same problem running Rails 4.1.5 on CentOS 6.5.

I fixed it by:

  1. Installing the sqlite dev library (On CentOS it's $ yum install -y sqlite-devel); and
  2. Installing the sqlite3 gem with gem install sqlite3.

I was able to create a new rails project afterward.

  • Stigly & tanuj thank you, this didn't help but I may not be transliating it to mac osx properly. Thanks for the idea – Shazam Sep 17 '14 at 12:44
