Net::SCP::Error (SCP未成功完成())：

Question

我有一个脚本，它将执行从一个服务器到另一个服务器的文件传输，但它给出了一个错误：

Net::SCP::Error (SCP did not finish successfully ()):

有人能帮我吗？这是我的代码。

Net::SCP.start( 's.com', 'username', :password => 'password' ) do|scp|
  scp.upload!( source, destination )
end

Answer 1

我今天遇到了这个问题。发现我的本地文件(在您的示例中是source)指向了一个不存在的文件。祝好运。

Answer 2

如果要将文件上载到远程服务器上尚不存在的文件夹，也会发生此错误。在SCP中，文件夹创建不是隐式的

Answer 3

我有一个稍微不同的错误，在括号中包含了退出代码：

Net::SCP::Error Exception: SCP did not finish successfully (1)

一开始，我认为这可能是由于源文件不存在或目标目录不存在而引起的，但事实证明这是因为我传递的是源文件的路径名对象，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")

"gems/net-scp-1.0.4/lib/net/scp.rb:279:in `upload!'",

文件正在被复制到正确的远程位置，但net-ssh中的某些内容退出了1而不是0，我没有费心去查找该调用在堆栈跟踪中的位置

# 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 }

只需将路径名对象改为字符串即可使一切正常工作

my_file = Rails.root.join('config/my_file').to_s
scp.upload!(my_file,  "/var/tmp/dev.pub")
