Net :: SSH :: Expect ..Cipher选项是否给出了Iillegal参数错误？

Question

我尝试使用以下构造函数连接到一个设备

my $ssh = Net::SSH::Expect->new(
user => $user,
host => $host,
password  => $password,
cipher => $cipher,
user => $user,
timeout => $timeout,
raw_pty =>1,);

并低于错误 IllegalArgument属性＆＃39; cipher＆＃39;不是有效的构造函数参数。在cipher.pl第34行 有人可以提供建议吗？ 这是模块代码的片段，它认为这接受了密码＆＃39;

sub connect {
my Net::SSH::Expect $self = shift;
  my $cipher = $self->{cipher};
