我知道这是一个古老的问题，但是在尝试找到解决问题的方法时，我偶然发现了这里。这与问题中显示的错误日志相同。至少在Windows下，这似乎是旧红宝石的普遍问题。
我正在运行Cygwin under Windows 7 x64, with RVM and Ruby 2.2.6，是的，我知道它已经老了。
在用RVM安装Ruby时，我遇到了类似的问题，但后来我暂时解决了，我认为这只是在制作红宝石时。但是现在我在做bundle exec cap some_env deploy时遇到了同样的问题，capistrano在使用net-ssh时，出现了与问题中相同的错误。
问题是Fiddle#dlopen没有尝试使用扩展名.dll。在当前使用Fiddle.dlopen("user32")的调用中导致错误的情况下，应该使用Fiddle.dlopen("user32.dll")进行尝试。
我在第ruby-2.2.6/lib/ruby/2.2.0/fiddle/import.rb行的第83行附近做了一个破解程序：
begin
Fiddle.dlopen(lib)
rescue DLError
raise(DLError, "can't load #{lib}")
end
我将其更改为
begin
Fiddle.dlopen(lib)
rescue DLError
if lib.to_s !~ /\.dll/
lib = "#{lib}.dll"
retry
end
raise(DLError, "can't load #{lib}")
end
它有效。
