错误：RegexpError：使用刀引导时

Question

ERROR: RegexpError: end pattern with unmatched parenthesis: /^(no$/i

在运行knife bootstrap 命令引导节点时。我正在使用我的本地 MAC 机器作为工作站来设置节点，我在这里找到了一篇类似的帖子 RegexpError in chef when running knife bootstrap 但我在我的 ./ssh/config 文件中没有看到任何问题。我什至尝试从文件中删除所有 cmets，还尝试创建一个空的配置文件，但似乎没有任何效果，非常感谢您对此的任何帮助。

谢谢

我通过添加 -V -V 选项在调试模式下运行引导命令并分析了日志。

knife bootstrap <ip-address> -V -V -x <username> -P <password> --sudo -N <node-name>

我得到了以下调试日志

当我查看节点实例中的/opt/chefdk/embedded/lib/ruby/gems/2.1.0/gems/net-ssh-3.0.2/lib/net/ssh/config.rb 文件时，我首先看到的是 cmets：

The Net::SSH::Config class is used to parse OpenSSH configuration files,
  # and translates that syntax into the configuration syntax that Net::SSH
  # understands. This lets Net::SSH scripts read their configuration (to
  # some extent) from OpenSSH configuration files (~/.ssh/config, /etc/ssh_config,
  # and so forth).

我的 ~/.ssh/config 文件是正确的，但我的 /etc/ssh_config 文件存在问题，它在同一行中有多个带有 () 的 cmets，例如：Host * # (no default)。我摆脱了 ssh_config完全文件，因为它没有在我的系统中的任何地方使用，并再次尝试了刀引导命令，没有任何问题。另一种选择可能是修复所有 cmets 并从 cmets 中删除 ()。
