【问题描述】:
尝试调用 Rails 控制台 (bundle exec rails c) 或 Rails 服务器 (bundle exec rails s) 会引发以下异常:
~/project/.bundle/gems/railties-4.2.6/lib/rails/railtie/configuration.rb:95:in `method_missing': undefined method `action_mailer' for #<Rails::Application::Configuration:0x007fdbe46e7400> (NoMethodError)
from ~/project/config/environments/development.rb:43:in `block in <top (required)>'
from ~/project/.bundle/gems/railties-4.2.6/lib/rails/railtie.rb:210:in `instance_eval'
from ~/project/.bundle/gems/railties-4.2.6/lib/rails/railtie.rb:210:in `configure'
from ~/project/config/environments/development.rb:1:in `<top (required)>'
from ~/project/.bundle/gems/activesupport-4.2.6/lib/active_support/dependencies.rb:274:in `require'
...
我是否遗漏了一些可能导致不兼容问题的东西?
这是config/environments/development.rb 中的违规行:
# Save emails to files instead of delivering.
config.action_mailer.delivery_method = :file
以下是我的 Gemfile 的内容:
source 'https://rubygems.org'
gem 'rails', '4.2.6'
gem 'activemodel'
gem 'actionmailer'
gem 'sass-rails', '~> 5.0.0'

【问题讨论】:
-
之前是否有效或从未有效?
-
它从来没有奏效。这是我第一次尝试使用和配置 actionmailer。
-
尝试从您的 gemfile 中剩余的 actionmailer 然后捆绑安装
-
这没有任何区别,即使从头开始重新安装所有 gem。
-
没有
bundle exec也能工作吗?
