Hi Jeremy,
The "hobo new" command executed the "rails new" command using a system
call. This is the code:
puts "Generating Rails infrastructure..."
system "rails new #{app_name} #{ARGV * ' '} -m #{template_path}"
This means that whatever Rails version has been installed last is used
the generate the empty app, to which Hobo laters adds a lot of
customisations. A simple workaround should be reinstalling rails 4.0.8
before creating a new Hobo app.
I can envision several ways of solving this for future users:
- Make Hobo check that "rails -v" returns a compatible version with the
installed version of Hobo. If not, print a helpful message like: "This
Hobo version requires Rails 4.0.x. Please install/reinstall Rails 4.0.8
with the folloring command and try again."
- Generate a small temporary Gemfile and use bundle exec to ensure we
are using the right version.
Any other suggestions?
Warm regards,
Ignacio
