I've trying to implement dashing on a raspberry(1) witj raspbian (jessie lite). Once i've installed raspbian, i've done the following things with success :

sudo apt-get update sudo apt-get install libssl-dev sudo apt-get install ruby-dev sudo apt-get install nodejs sudo apt-get install bundler sudo apt-get install rubygems sudo gem install dashing

sudo dashing new dashboard_project

I get the following error :

/usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in gem_original_require': no such file to load -- json (LoadError) from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:inrequire' from /var/lib/gems/1.8/gems/dashing-1.3.7/lib/dashing/downloader.rb:3 from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in gem_original_require' from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:inrequire' from /var/lib/gems/1.8/gems/dashing-1.3.7/bin/dashing:7 from /usr/local/bin/dashing:23:in `load' from /usr/local/bin/dashing:23

Do you have any idea of what should i do ?

Thanks !

Post 'gem list json' to see whether json module is installed. If not, then try installing it with 'gem install json'.

  • From the path you provided in your answer, it seems that your default ruby is 1.8. Check what version exactly are you running. Maybe something like gem -v might help to see what is being run as gem.
