package.rb:117: syntax error, unexpected keyword_end, expecting $end

Hi, noob at ruby but was redirected from here as I'm trying to package a local buildpack. I've followed the steps in the md file and am getting the following ruby stack trace:

$ buildpack-packager list

I looked in package.rb and I can't see any unbalanced end statements. What am I missing?

We have created an issue in Pivotal Tracker to manage this. You can view the current status of your issue at: https://www.pivotaltracker.com/story/show/101115084.

You are using Ruby 1.9.3 but buildpack-packager requires Ruby 2.1+. The cf.Gemfile in each buildpack specifies the required Ruby version.

Maybe we should lock the version of the supported Ruby for buildpack packager in the gemspec.

jameskhedley commented 9 years ago

Thanks! It's working now. For the uninitiated you can do:

rvm install 2.2.0
rvm --default use 2.2.0

before running step 2 'bundle install'.

Maybe you could add something to make it more obvious that we should use > 2.1? It's not easy to deduce the cause from the error message currently.

Thanks again.

Note that I've created this Tracker story to specify supported Ruby versions in the gemspec:
