Question

我的代码

IMAGE_DIR = 'D:\File_Server\Nisa_Costcutter\Master Nisa CC Logos'

require 'net/ssh'
require 'net/scp'

def scopy_file(file)
  puts "Transferring #{file.path}"
  Net::SCP.upload!('192.168.254.5', 
                   'passenger', 
                    file, 
                    '/var/www/pinpointlms.co.uk/shared/logos', 
                    :ssh => {password: '*****'})
end

puts "Starting Upload"

Dir.foreach(IMAGE_DIR) do |name|
  if name.length > 4 && name[-4..-1].upcase == '.BMP'

    filename=name.strip()
    file = File.new(File.join(IMAGE_DIR, filename))

    if (Time.now - file.mtime) > 86400
        scopy_file(file) 
    end


  end


end
puts "End of Transfer"

我正在尝试使用Ruby将一些文件从Windows框复制到Ubuntu框但我得到以下输出：

Answer 1

您可能没有用户访问权限来在Ubuntu服务器上的给定目录“/var/www/pinpointlms.co.uk/shared/logos”中上传（写入）该文件。

尝试保存它而不给它一个完整的路径，因此它最终会出现在Ubuntu服务器上的用户主目录中。如果这样可行，那么您的问题与服务器上的用户权限有关。

Answer 2

如果它对其他人有帮助，那么在尝试将文件上传到尚未存在的路径时，我会得到完全相同的错误。来自shell的scp将允许你这样做，但Net :: SCP将因此错误而失败。

即

scp "my.file" "/foo/bar/"

如果/ foo存在但/ foo / bar /不存在，scp将创建/ foo / bar并将文件放在那里（假设权限允许你这样做）。

然而 - 在相同的情况下 - 这将失败，问题中给出错误

scp.upload!(my_file, "/foo/bar/")

我找到的唯一解决方案是首先在本地创建您想要的路径，然后使用：recursive选项上传，如下所示：

scp.upload!("bar/", "/foo" :recursive => true)

其中./bar包含my_file。

SCP没有成功完成（1）尝试使用ruby从Windows上传到Ubuntu时出错
