无法在Rails 4.0中安装原子红宝石原子宝石

Question

I've been doing quite a bit of research on this issue the last week or so but haven't found a solution that works for me, it's very frustrating. Hopefully somebody can point me in the right direction. Here's the error I recieve

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

/Users/Name/.rvm/rubies/ruby-2.0.0-p247/bin/ruby extconf.rb
* extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Gem files will remain installed in /Users/Name/.rvm/gems/ruby-2.0.0-p247@swi----ense/gems/atomic-1.1.12 for inspection. Results logged to /Users/Name/.rvm/gems/ruby-2.0.0-p247@sw-----nse/gems/atomic-1.1.12/ext/gem_make.out

An error occurred while installing atomic (1.1.12), and Bundler cannot continue. Make sure that gem install atomic -v '1.1.12' succeeds before bundling.

Answer 1

This should work:

gem install atomic -V

And then:

gem install rails -V

The -V is for Verbose. You'll see what happen. It worked for me on a Linux box, when gem update didn't.

You also need to have the latest rubygem / bundler.

Answer 2

This happened to me because I didn't have the right version of XCode Developer Tools for OS X Mavericks. Then when I tried to update it, it said it wasn't available from the Software Update server. Details here .
