Ruby on rails 未定义的局部变量或方法`远程化身url'；对于main:Object

我已经在carrierwave文档中安装了AvatarUploader

class User < ApplicationRecord
  mount_uploader :avatar, AvatarUploader

NameError:未定义的局部变量或main:Object的“remote\u avatar\u url”方法

你忘了带冒号：

FactoryGirl.create(:user, :remote_avatar_url => ...
                          ^ 

你忘了带冒号：

FactoryGirl.create(:user, :remote_avatar_url => ...
                          ^ 

NoMethodError（未定义的方法'split'for#）：`` FactoryGirl.create（：user，：remote_avatar_url=>URI.parse（“））NoMethodError:from/home/vamsi/.asdf/installs/ruby/2.4.1/lib/ruby/gems/2.4.0/gems/carrierwave-1.0.0/lib/carrierwave/uploader/downloader.rb:88:inrescue-in-process`` nomethodorror'（对于#）未定义的方法'split'：``FactoryGirl.create（：user，：remote\u avatar\u url=>URI.parse（“））NoMethodError:from/home/vamsi/.asdf/installs/ruby/2.4.1/lib/ruby/gems/gems/carrierwave-1.0.0/lib/carrierwave/uploader/downloader.rb:88:inrescue-in-in-URI'```
