Solve the following python programming problem given the following code:
def _runWorker(self, worker_id, logDir) : 
    iteration = 0 
    while (worker_id in self.threads) : 
        iteration += 1 
        log_path = self._workerLogFile (worker_id, iteration, logDir) 
        logging.info ('adding worker. script: %s, log: %s', self.worker_path, log_path) 
        with open (log_path, 'a') as logfile : 
            def writeline(msg) : 
                logfile.write ((msg + '
')) 
env = dict (os.environ) 
            env ['UFORA_WORKER_BASE_PORT'] = str ((30009 + (2 * self.num_ever_started))) 
            self.num_ever_started += 1 
            proc = SubprocessRunner.SubprocessRunner ([sys.executable, '-u', self.worker_path], writeline, writeline, env = proc) 
            logfile.write ('***Starting worker***
') 
            logging.info ('Starting worker %s', worker_id) 
            logfile.flush () 
            proc.start () 
            self.processes [worker_id] = proc 
            proc.wait () 
            logging.info ('Worker exited: %s', worker_id) 

    
    

    Fix the buggy line: proc = SubprocessRunner.SubprocessRunner ([sys.executable, '-u', self.worker_path], writeline, writeline, env = proc)
