为什么会发生这种情况......我无法理解......？任何建议
答案 0 :(得分：0)
那是你的问题：
uninitialized constant CONFIG (NameError)
这是您的解决方案（将CONFIG var替换为您的实际数据）：
#config/environments/development.rb
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: 'smtp.gmail.com',
port: 587,
domain: *************,
authentication: 'plain',
enable_starttls_auto: true,
user_name: *************,
password: ************
}
我建议您使用Figaro gem来访问ENV个变量（因此您可以像CONFIG一样使用它们，但ENV}
