CarrierWave使用时fog错误

1：

Add this to your Gemfile:

gem 'net-ssh'

and run bundle install after that.

2：（正确）

Alternatively, add this to your Gemfile:

gem 'fog', '~> 1.36.0'

and run bundle install. This worked for me, because I was hitting a bug introduced in 1.35.0: https://github.com/fog/fog/issues/3765
