Grateful for reports from other platforms. INSTALLATION Note that this compiles the underlying c code, which might take 10-20 minutes or so gem install decc_2050_model UPDATING TO NEWER VERSIONS OF EXCEL MODEL First of all, you need to be working on the github version of the code, not the rubygem: git clone http://github.com/decc/decc_2050_model Then put the new spreadsheet in spreadsheet/2050Model.xlsx Then, from the top directory of the gem: bundle rm ext/decc_2050_model.c bundle exec rake The next step is to check whether lib/decc_2050_model/decc_2050_model_result.rb and lib/decc_2050_model/model_structure.rb need to be altered so that they pick up the correct places in the underlying excel. The final stage is to build and install the new gem: gem build decc_2050_model.gemspec gem install decc_2050_model-.gem ... where is the version number of the gem file that was created in the folder.
