I’ve been playing with CouchDB lately, and the CouchObject Ruby bindings. When I tried to install the latest CouchDB gem with sudo gem install couchobject-0.5.0 it fails because json isn’t installed. Then I ran sudo gem install json, which failed with:
Building native extensions. This could take a while...
ERROR: While executing gem ... (Gem::Installer::ExtensionBuildError)
ERROR: Failed to build gem native extension.
ruby extconf.rb install json
extconf.rb:1:in `require': no such file to load -- mkmf (LoadError)
from extconf.rb:1
According to this article, Ubuntu breaks up Ruby stuff into multiple packages for various and irrelevant reasons, so doing sudo apt-get install ruby doesn’t cut it. sudo apt-get install ruby1.8-dev, however, installed the additional crap needed to build Ruby extensions from source.
I has the same problem
I has the same problem trying intall json-ruby gem with the same error , then I reinstall ruby with apt-get install ruby1.8-dev well, its installing successfully but when I try to installl with apt-get intall json I obtained this error :
gem install json
Building native extensions. This could take a while… ERROR: Error installing json: ERROR: Failed to build gem native extension.
