The introduction (page xii) says to download the code and run the bin/setup script, but the process wasn’t quite that one-click for me – that’s fine, it’s a beta book! But if you’re like me and want to dive into the fun parts, I thought I’d share the steps I used to get the introduction/01 Rails server up and showing the sample data. I hunted in the various files to find what versions of Ruby/Rails/JS/etc. the author is currently using:
postgres$ createuser --login -P nxns
Enter password for new role:
Enter it again:
postgres$ createdb -O nxns -U postgres nxns_development
postgres$ createdb -O nxns -U postgres nxns_test
