Running in production mode fails

[He Qi]

Hi,

  I am new to rails and not sure if this is the correct place for newbie questions. I'm trying to deploy a small app in rails 5.2.1 to prod. In dev mode (-e development) it works but in prod mode (-e production) it throws error (see bottom). The only change I made after running rails new app is add a  local "gems" folder and add below code to Gemfile:

path './gems' do

  gem 'utils'

  gem 'dsl'

end

The rails version is 5.2.1 and ruby 2.3.0 on win7 64bit. Could anyone help or redirect me to the correct forum? Thank you in advance.

Regards,

He Qi
