正式參數不能是ruby中的類變量

Question

我以前從未使用過Ruby，並且試圖運行一個很早以前寫入 的程序。我已經安裝了Ruby 2.4.1和gem包[測試單元 3.4.3] OK，但是當我嘗試運行它，我得到一個錯誤：

tcreporter.rb:156: formal argument cannot be a class variable 
    @@tc_array.each do |@@tc| 
         ^

有什麼特別I」米做錯了嗎？ 下面的代碼片段：

class TCReporter 
    @@m = nil; @@c = nil; @@tc = nil; @@status = 'p'; @@notes = nil; @@tlArr = [] 
    @@resultMapping = {'p'=>'PASS', 'f'=>'FAIL', 'b'=>'BLOCKED', 's'=>'SKIP','pr'=>'PREQFAIL', 'con'=>'CONERR', 'h'=>'HWSKIP', 'cor'=>'CORE'} 

    def self.report_result(currentTest, status, notes=nil) 
    if $trInit 
     @@m = currentTest.split('(')[0] #@@m is the test METHOD currently being executed in the framework. 
     @@c = currentTest.split('(')[1].split(')')[0] #@@c is the test CLASS currently being executed in the framework 
     if @@c =~ /(?:#{TESTRAIL_TEST_PREFIXES.join('|')})_\d*$/i #If there's a mapping on the test class then report a test class result. 
      @@tc = @@c.scan(/(?:#{TESTRAIL_TEST_PREFIXES.join('|')})_\d*$/i)[0].upcase.sub('_', '-') #Get the TR class mapping 
      #When reporting at the test class level, the status always starts out as 'p' (PASS). If there's any 
      #non-passing status for any test method within the test class (blocked or failed) then use that result 
      #for reporting. Once the global status '@@status' has been updated once then no more updating occurs. 
      if @@status == 'p' && status != 'p' 
      @@status = status 
      @@notes = notes 
     end 
     if eval("#{@@c}.public_instance_methods.grep(/^test_/).sort.first") == @@m && eval("#{@@c}.public_instance_methods.grep(/^test_/).sort.last") == @@m #The first test method is the last test method. All done, do a TestLink update. 
     begin

     ensure 
      result.case_id = @@tc

      result.method = @@m

      end 
     end 
     elsif eval("#{@@c}.public_instance_methods.grep(/^test_/).sort.first") == @@m #A new test class is being evaluated. Set everything to default except status (use whatever the first test class returned). 
     @@m = nil; @@c = nil; @@tc = nil; @@status = status 
     elsif eval("#{@@c}.public_instance_methods.grep(/^test_/).sort.last") == @@m #Done with the test class. Time to report the test result.

      end 
     end 
     else #The test class is still being executed. Don't update TestLink yet, just check for a non-passing result. 
     if @@status == 'p' && status != 'p' #Update the test status if it's a non-pass result. Otherwise, use the earlier failed or blocked status. 
      @@status = status 
     end 
     end 
     end

這是使「TC」爲局部變量之後，現在固定。
