Question

I an trying to install redmine but get an issue when I do bundle install

An error occured while installing json (1.7.3), and Bundler cannot continue.
Make sure that gem install json -v '1.7.3' succeeds before bundling.

Have very little ruby experience so any help would be appreciated.

When you encounter this kind of error extconf.rb:1:in 'require': no such file to load -- [something] (LoadError), it means that a package on your system is missing.

On Ubuntu for instance, you can install mkmf which is part of ruby18-dev like this :

sudo apt-get install ruby18-dev
