#<OpenSSL::PKey::RSA:0x00563aaff72138> 的未定义方法“e=”

Question

我正在尝试使用 net/sftp gem 从 Heroku 的 SFTP To Go 下载文件，但我总是得到未定义的方法 `e=' for #。

一直在网上搜索，但找不到任何相关的解决方案。这是我的代码：

task employer_email_import: :environment do
  require 'net/sftp'
  require 'uri'

  sftptogo_url = ENV['SFTPTOGO_URL']
  uri = URI.parse(sftptogo_url)

  Net::SFTP.start(uri.host, uri.user, :password => uri.password) do |sftp|
     sftp.download!("some_directory", "some_directory")
  end

end

错误： # 的未定义方法 `e=' 你的意思是？ e**********
