Gem::Ext::BuildError: ERROR: Failed to build gem native extension Mavericks

Question

am learning rails using this website http://tutorials.jumpstartlab.com/projects/blogger.html and whenever I try starting the server using rails server, I get this error on the terminal

Could not find gem 'sqlite3 (>= 0) ruby' in the gems available on this machine.
Run `bundle install` to install missing gems.

After running the command bundle install , I get the error:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Answer 1

I don't know if this will help people with this issue but I was having the same error. What I ended up doing to fix it is commenting out the sqlite gem in my gemfile for the app. Granted I just did this a few minutes ago so I don't know if I'll run into any other issues but I use Postgres so if you use something else too, there shouldn't be an issue. Hope this helps others like me that were looking for answers.

Looks like bundler has no permission to write into your file system.

Permission denied @ rb_sysopen - /usr/local/Cellar/ruby/2.1.2_3/bin/rake (Errno::EACCES)

Try running your command as sudo:

sudo bundle install 

Answer 3

I believe the issue is the Gemfile.lock thats not allowing you to use the latest version of of each of your gems.

To update your Gemfile.lock run the command:

bundle update 

in the same directory as your Gemfile.lock file then try bundle install again.
