我一直在我的Rails API中上传和删除Cloudinary上的图片，直到我开始收到主题错误。我无法启动并运行服务器。
任何想法导致了什么？
我安装了cloudinary gem并在config / initializers / cloudinary.rb中配置了我的配置，并在application.yml中使用了我的凭据：
Cloudinary.config do |config|
config.cloud_name = ENV[CLOUDINARY_CLOUD_NAME]
config.api_key = ENV[CLOUDINARY_API_KEY]
config.api_secret = ENV[CLOUDINARY_API_SECRET]
config.secure = true
config.cdn_subdomain = true
end
我正在我的图像控制器中引用Cloudinary，如下所示：
result = Cloudinary::Uploader.upload(image, options = {})
以下是完整错误：
***作为更新，我将cloudinary网址放在我的application.yml中并注释掉了cloudinary.rb，它现在可以正常工作了，但是如果有人能说明为什么未初始化的常量错误出现了，我将不胜感激。 ****

答案 0 :(得分：1)
从共享的规范来看，似乎不是指定环境变量，而是将变量称为常量。
将代码更改为以下提及的内容：
Cloudinary.config do |config|
config.cloud_name = ENV["CLOUDINARY_CLOUD_NAME"]
config.api_key = ENV["CLOUDINARY_API_KEY"]
config.api_secret = ENV["CLOUDINARY_API_SECRET"]
config.secure = true
config.cdn_subdomain = true
end
