晚上好.我用ruby语言开发了一个程序，当我输入逗号“”时，我得到了一个错误，我无法解决它，请帮助我。

require "net/http"
require "colorize"
puts "+================================+".red
puts "|        ABDO[panel-scan]        |".green
puts "+================================+".red
pages = {'admin.php','loginpage.php','index.php','login.php'}
print "Enter url site : "
site = gets.chomp 
for i in pages
    url = URI(site)
    web = Net::HTTP.get_response(url + i)
    puts "[-] #{url}#{i} ".blue + " | ".red + web.code + " | ".red + web.message
    if web.message == 'ok'
        puts "[^_^] admin panel Found ".yellow
    end
end

错误是：

syntax error, unexpected ',', expecting => (SyntaxError)
pages = {'admin.php','loginpage.php','index.php','...
                    ^
