puppet open3.capture3 返回 127 not found

如何解决puppet open3.capture3 返回 127 not found

我正在尝试为 puppet 编写自定义函数。 这是：

require 'open3'                                                                                                                                                                                   
                                                                                                                                                                          
Puppet::Functions.create_function(:'clickhouse::query') do                                                                                                                               
  # Headers (somehow are called signatures in puppet)                                                                   
  dispatch :query do                                                                   
    param 'String',:query_string                                                                   
    param 'String',:db_user                                                                   
    param 'String',:db_password                                                                   
    optional_param 'Integer',:db_timeout                                                                   
    optional_param 'String',:bin_path                                                                   
    return_type 'String'                                                                   
  end                                                                   
                                                                   
  # Implementations                                                                   
  def query(query_string,db_user,db_password,db_timeout=3,bin_path='/usr/bin')                                                                   
    cmd_string = "#{bin_path}clickhouse-client --user #{db_user}--password #{db_password} --idle_connection_timeout #{db_timeout} --query='#{query_string}';"    
      stdout,stderr,status = Open3.capture3(cmd_string,:binmode=>true)                                                                                        
      if not status.success?                                                                                                                                                                    
        raise Puppet::ParseError,"clickhouse::query failure: exitcode #{status.exitstatus} stdout #{stdout} stderr #{stderr}"                                                                 
      end                                                                                                                                                                                      
    return stdout                                                                                                                                                                              
  end                                                                                                                                                                                        
end          

我尝试了 capture3 和 popen3 的所有选项，但总是得到

错误：无法从远程服务器检索目录：服务器上的错误 500：服务器错误：评估错误：评估函数调用时出错，clickhouse::query 失败：exitcode 127 stdout stderr sh：1：clickhouse-client：not找到

我尝试了 /usr/bin/clickhouse-client,/usr/bin/clickhouse client,PATH=/usr/bin /usr/bin/clickhouse-client,/bin/bash -c "/usr/bin/clickhouse-client" 但总是得到相同的结果。

也许有什么秘诀？

顺便说一句：/usr/bin/clickhouse-client 存在

# /usr/bin/clickhouse-client
