Hello, Ubuntu server 16.04 - Running Rbenv ruby 2.5.1 - with multiple apps up and running - rails 5.2.0 A recent attempt with current version yields this: running --> rails new myapp -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb 1. Build a railsapps starter example application 6. rails-devise no email 1. puma same as development 3. MySql 1. ERB 1. none 3. Bootstrap 3.3 1. add jquery-rails gem 2. gmail 1. Devise with default modules 1. none 6. bare 1. none 1. no disable turbolinks yes set robots.txt yes github no add therubyracer yes Adding install log and my gems local list [gem_list_fail_composer.txt](https://github.com/RailsApps/rails-composer/files/2124587/gem_list_fail_composer.txt) [install_log_mysql_fail_composer.txt](https://github.com/RailsApps/rails-composer/files/2124588/install_log_mysql_fail_composer.txt) I've done the same with SQlite3, no problems. I already have an app up and running on latest with the latest. Suggestion: Composer when detected multiple mysql gems give you an option to select, or give the option to select multiple versions to deploy. Thanks!
