我有一個腳本，它會做從一個服務器上的文件轉移到另一個，但它給出了一個錯誤：的Net :: SCP ::錯誤（SCP沒有成功完成（））：
Net::SCP::Error (SCP did not finish successfully()):
可以在任何身體幫助我？這是我的代碼。
Net::SCP.start('s.com', 'username', :password => 'password') do|scp|
scp.upload!(source, destination)
end
我今天有這個問題。發現我的本地文件（在你的例子中，來源）指向一個不存在的文件。祝你好運。
如果要將文件上傳到遠程服務器上尚不存在的文件夾，也會發生此錯誤。創建文件夾不是隱含在SCP中
我有這個問題，只是修復它。 本地和遠程路徑的原因應該是完全路徑，如'/ home/root/folder'，而不應該是'〜/文件夾'。
這是我的問題，面對它與[capistrano寶石]（https://github.com/sgruhier/capistrano-db-tasks/blob/master/lib/capistrano-db-tasks/database.rb）是這個一個錯誤？ – 2014-05-24 07:06:32
我有一個rakefile.rb，它定義了一個使用net/scp和基本密碼認證將文件上傳到遠程服務器的任務，即使我檢查了一個「Net :: SSH :: AuthenticationFailed」異常主機，用戶，密碼和文件字符串。我啓用
LogLevel INFO
到
LogLevel DEBUG
然後看到下面的輸出在服務器的日誌（例如，/var/log/auth.log），發現客戶端試圖使用公共密鑰認證因爲某些原因！

所以看到發生了什麼事情我改變了我的代碼，包括：在SCP的選項SSH密鑰，指定我只支持密碼認證：
Net::SCP.upload!(:remote_server, :remote_user, local_file, remote_file,
{
:password => "(my password)",
:ssh => {:auth_methods => ["password"]}
}
)
，這導致在服務器上的以下信息：

顯然他們未能就如何做認證同意....希望這是人們通過它來幫助。如果/當我發現爲什麼會發生這種情況時，我會更新它。
我有一個稍微不同的錯誤，包括在括號退出代碼：
Net::SCP::Error Exception: SCP did not finish successfully (1)
我起初這會已經引起源文件不存在或爲其他人所說的不存在目標目錄想通，但事實證明是因爲我傳遞的是源文件的路徑名對象而不是字符串。
my_file = Rails.root.join('config/my_file') # my_file.class => Pathname
scp.upload!(my_file, "/var/tmp/dev.pub")
<Net::SCP::Error: SCP did not finish successfully (1)>
"gems/net-scp-1.0.4/lib/net/scp.rb:352:in `start_command'", "gems/net-ssh-2.6.7/lib/net/ssh/connection/channel.rb:590:in `call'",

"gems/net-ssh-2.6.7/lib/net/ssh/connection/session.rb:459:in `dispatch_incoming_packets'",
"gems/net-ssh-2.6.7/lib/net/ssh/connection/session.rb:216:in `preprocess'", "gems/net-ssh-2.6.7/lib/net/ssh/connection/session.rb:200:in `process'",
"gems/net-ssh-2.6.7/lib/net/ssh/connection/session.rb:164:in `loop'", "gems/net-ssh-2.6.7/lib/net/ssh/connection/session.rb:164:in `loop_forever'",
"gems/net-ssh-2.6.7/lib/net/ssh/connection/session.rb:164:in `loop'", "gems/net-ssh-2.6.7/lib/net/ssh/connection/channel.rb:269:in `wait'",
"gems/net-scp-1.0.4/lib/net/scp.rb:279:in `upload!'",
該文件已被複制到正確的位置偏遠，但一些在網SSH被退出1而不是0，我一直懶得去找到此電話是在堆棧跟蹤
# gems/net-scp-1.0.4/lib/net/scp:352
channel.on_close { |ch| raise Net::SCP::Error, "SCP did not finish successfully (#{ch[:exit]})" if ch[:exit] != 0 }
只是改變了路徑對象的字符串使一切工作
my_file = Rails.root.join('config/my_file').to_s
scp.upload!(my_file, "/var/tmp/dev.pub")
輝煌。這樣的事情我也經歷過。這應該在Gem中真正解決。 – slhck 2014-08-12 10:04:41
我知道這是舊的和回答，但我得到這個錯誤，當我試圖下載與Net :: SCP。對我來說問題是遠程SSH主機沒有安裝'openssh-clients'。 – ZombieDev 2014-04-03 16:12:57
