ERROR: RegexpError: end pattern with unmatched parenthesis: /^(no$/i
运行knife bootstrap命令以bootrtap一个节点。我使用我的本地MAC机作为工作站来设置节点，我在这里发现了一个类似的帖子RegexpError in chef when running knife bootstrap但我在./ssh/config文件中没有看到任何问题。我甚至尝试从文件中删除所有注释，并尝试创建一个空的配置文件，但似乎没有任何工作，非常感谢任何帮助。

我通过添加-V -V选项在调试模式下运行bootstrap命令并分析日志。
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，我看到的第一件事是评论：
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（）的注释，例如：Host * # (no default)。我摆脱了ssh_config文件完全没有在我的系统中的任何地方使用，并再次尝试使用knife bootstrap命令而没有任何问题。另一种选择可能是修复所有评论并删除（）形成评论。
