Weechat Ruby插件-尝试要求任何gem都会导致错误

我正在尝试创建一个使用mysql2的插件，它将允许从IRC到数据库的通信

我面临的问题是，如果插件没有崩溃，我不能要求任何gem加入插件

require 'mysql2'
@client = nil
def weechat_init
  Weechat.register('sql', 'Ninjex', '1.0', 'GPL3', 'Execute MySQL commands: /sql <query>', '', '')
  Weechat.hook_command('sql', 'Execute MySQL database commands', '', '', '', 'sql', '')
  return Weechat::WEECHAT_RC_OK
end

def sql(data, buffer, args)
  buffer = Weechat.current_buffer
  con_flag = '-c'
  explode = args.split(' ')
  if explode[0] == con_flag
    #Weechat.buffer_set(buffer, 'localvar_set_con', explode.drop(1).join.strip)
    con_info = explode.drop(1) # ["localhost", "username", "password", "database"]
    hostname = con_info[0]
    username = con_info[1]
    password = con_info[2]
    database = con_info[3]
    @client = Mysql2::Client.new(:host => hostname, :username => username, :password => password, :database => database)
    Weechat.print(buffer, "MySQL client created!")
  else
    row_count = 0
    Weechat.command(buffer, "Sending query: #{args}")
    sql_res = @client.query(args)
    sql_res.each(:as => :array) {|r| row_count += 1; Weechat.command(buffer, "RESULT [#{row_count.to_s}]: "+r.to_s)}
    return Weechat::WEECHAT_RC_OK
  end
end

我注意到的一点是：

ninjex@kali：~$ruby-v
ruby 2.1.1p76（2014-02-24修订版45161）[i686 linux]

我使用的是ruby 2.1.1，错误输出显示它在：

/usr/lib/ruby/1.9.1/rubygems/

在交互式Ruby会话或常规Ruby脚本中加载

mysql2

会成功。只有在尝试将此应用于weechat时，我才会收到错误

任何帮助都将不胜感激，如果是gem路径，我不知道如何更改正在加载的gem的路径。

我解决了这个问题。Weechat当前版本不支持Ruby>=2.1.x

不幸的是，修复程序正在运行Weechat witch Ruby
