I just installed the heroku ruby gem on Windows 7 and received the following error when trying to create a new instance. Have been researching the cause for the past two days with no luck.
C:\Users\admin\RubymineProjects\first_app>heroku create
Invalid gemspec in [C:/RailsInstaller/Ruby1.8.7/lib/ruby/gems/1.8/specifications

Try one of the following solutions (if you haven’t already) – this isn’t specific to Windows:
Invalid date format specification in gemspec
invalid date format in specification
Invalid gemspec because of the date format in specification
