I should mention that I 'm following the book Learn Ruby on Rails: Book Two by Daniel Kehoe, I use ZSH I'm working on OSX Captain.
I would greatly appreciate your help. I'm working on a new project on rails and am newbie in this environment
that in my Gemfile
source 'https://rubygems.org'
ruby '2.3.0'
gem 'rails', '4.2.6'
# Rails Default
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'

end
Development.rb:
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false
# Do not eager load code on boot.
config.eager_load = false
# Show full error reports and disable caching.
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
# Don't care if the mailer can't send.
config.action_mailer.raise_delivery_errors = false
# Print deprecation notices to the Rails logger.
config.active_support.deprecation = :log
# Raise an error on page load if there are pending migrations.
config.active_record.migration_error = :page_load

# number of complex assets.

config.action_mailer.raise_delivery_errors = true
# Send email in development mode?
config.action_mailer.perform_deliveries = true
# Asset digests allow you to set far-future HTTP expiration dates on all assets,
# yet still be able to expire them through the digest params.
config.assets.digest = true
# Adds additional error checking when serving assets at runtime.
# Checks for improperly declared sprockets dependencies.
# Raises helpful error messages.
config.assets.raise_runtime_errors = true
# Raises error for missing translations
# config.action_view.raise_on_missing_translations = true
end
回答1:
Change of config.action.mailer to config.action_mailer.
That's on the line that currently says: config.action.mailer.smtp_settings, Hence the error you are getting. config has a action_mailer method, but not action.
回答2:
on line #30, change action.mailer to action_mailer... should work
回答3:
Try Add to wrap your development.rb in something like:
ApplicationName::Application.configure do
//your current development.rb file
end
ps: replace ApplicationName by yours.
