rails 从 Heroku 迁移到专用服务器后，为 #<Recaptcha 生成 dragonfly returns 未定义方法 `public_key='
rails generate dragonfly returns undefined method `public_key=' for #<Recaptcha after migrating from Heroku to dedicated server
站点已从 Heroku 迁移到专用 Ubuntu 服务器，迁移后站点正常运行，除了托管在 S3 上的图像。
加载带有图片的页面时，会出现以下类型的错误return：

我可以看到应用程序没有在 gemfile 中列出 dragonfly，因为 Heroku 似乎做事有点不同，并重新安装了 dragonfly，但是在尝试生成配置文件时出现以下错误 return编辑

Recaptcha 本身似乎工作正常，bundle install 没有 return 任何错误，但我无法让 dragonfly 工作。
recaptcha.rb 看起来像这样
Recaptcha.configure do |config|
config.public_key = 'public key'
config.private_key = 'private key'
config.api_version = 'v2'
end
我创建了不存在的 .env 文件，内容如下：
export RECAPTCHA_PUBLIC_KEY = 'public key'
export RECAPTCHA_PRIVATE_KEY = 'private key'
我也尝试手动添加到 config/environments/production.rb 和 config/environments/development.rb 以下：
recaptcha_public_key= "[PUBLIC KEY]"
recaptcha_private_key= "[PRIVATE KEY]"
我不确定我在这里遗漏了什么，在从 Heroku 迁移到独立系统后，有人对蜻蜓和 recaptcha 有任何经验吗Linux 系统
他们用版本 4 更改了 API，因此如果您通过 gemfile 安装它而不指定版本并且它默认为版本 4，您需要在配置中进行更改。
来自他们的CHANGELOG.md：
4.0.0 - 2016-11-14
public_key -> site_key and private_key -> secret_key
将您的 config/initializers/recaptcha.rb 更改为：
Recaptcha.configure do |config|
config.site_key = 'public key'
config.secret_key = 'private key'
...
