Problem Running app

[DavidYB]

Hi all, hope someone can help here.

I am new to rails and have a 'beginers problem'. I am on a Windows 7 64 bit machine with Rails 5.1.4 and Ruby 2.3.3.

When I try and run a new app, I get the following error

C:\Ruby On Rails\apps\test3_app>rails test3_app --trace rails aborted! Don't know how to build task 'test3_app' (see --tasks) C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/rake-12.3.0/lib/rake/task_m anager.rb:59:in []' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/rake-12.3.0/lib/rake/applic ation.rb:159:in invoke_task' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/rake-12.3.0/lib/rake/applic ation.rb:116:in block (2 levels) in top_level' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/rake-12.3.0/lib/rake/applic ation.rb:116:in each' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/rake-12.3.0/lib/rake/applic ation.rb:116:in block in top_level' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/rake-12.3.0/lib/rake/applic ation.rb:125:in run_with_threads' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/rake-12.3.0/lib/rake/applic ation.rb:110:in top_level' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/railties-5.1.4/lib/rails/co mmands/rake/rake_command.rb:21:in block in perform' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/rake-12.3.0/lib/rake/applic ation.rb:186:in standard_exception_handling' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/railties-5.1.4/lib/rails/co mmands/rake/rake_command.rb:18:in perform' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/railties-5.1.4/lib/rails/co mmand.rb:46:in invoke' C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/railties-5.1.4/lib/rails/co mmands.rb:16:in <top (required)>' bin/rails:4:in require' bin/rails:4:in

Any ideas ?

Thanks in advance
