到目前为止，我已经成功安装了Chef-server，chef-manage（UI位），并且使knife ssl check正常工作。
现在，我正在运行以下命令
knife ec2 server create -r 'role[webserver]' -I ami-0970010f37c4f9c8d -f t2.micro --region ap-southeast-2
我已将我的访问密钥和秘密密钥保存在knife.rb文件中，如下所示：
# See https://docs.getchef.com/config_rb_knife.html for more information on knife configuration options
current_dir = File.dirname(__FILE__)
log_level :info
log_location STDOUT
node_name "tuser"
client_key "#{current_dir}/tuser.pem"
chef_server_url "https://3.227.234.41/organizations/testdemo"
cookbook_path ["#{current_dir}/../cookbooks"]
knife[:aws_access_key_id] = "XXXXXXXXXXXXXX"
knife[:aws_secret_access_key] = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
不幸的是，我收到以下错误：

以下命令也会产生错误
PS C:\Users\hp\chef-repo> knife ec2 server create -I ami-0970010f37c4f9c8d -f t2.micro --region ap-southeast-2 -VVV

任何想法是什么问题？另外，我们可以像Ansible一样使用yaml文件代替命令行吗？
错误在这里报告：

您还应该指定一个密钥对，以SSH进入EC2
