Chef infra 无法在chef中创建用户（ruby错误）

我正在学习chef，我在为chef创建用户时面临一个问题

要执行的命令：

chef-server-ctl user-create USER_NAME FIRST_NAME [MIDDLE_NAME] LAST_NAME EMAIL 'PASSWORD' --filepath /path/to/username.pem

错误：

/opt/opscode/embedded/service/omnibus-ctl/wrap-knife-opc.rb:43:in `block (2 levels) in load_file': undefined method `exitstatus' for nil:NilClass (NoMethodError)

我通过降级chef版本解决了这个问题。 也可以通过更新ruby gems“gems update”

希望它能帮助查找此错误的人

什么版本的Chef Server？您可以通过运行chef server ctl--version来检查，我想是的。我想它也没有启动。。请检查，因为我已经在上面更新了这是rpm:chef-server-core-12.7.0-1.el7.x86_64.rpm，我正在rhel 7上执行此操作您降级到哪个版本？
