下一個python-brisa代碼在Eclipse中工作,但如果我從shell執行它,它會卡住。我認爲這個問題在reactor.main()中。因爲如果我評論它並創建一個無限循環,該程序將在Eclipse和shell中工作。任何想法如何解決它?Python-brisa在Eclipse中工作,但不在shell中

Python版本是2.6.6,我使用的是Debian Testing(wheezy)。

#!/usr/bin/env python 

from brisa.core.reactors import install_default_reactor 
from brisa.core.threaded_call import run_async_function 

reactor = install_default_reactor() 

import thread 
import sys 

from brisa.upnp.control_point.control_point import ControlPoint 

class CommandLineCtrlPoint(ControlPoint): 

    def __init__(self): 
     ControlPoint.__init__(self) 
     self.running = False 
     self.commands = {'option1': 'option1', 
         'option2': 'option2', 
         'option3' :'option3', 
         'help': self._help} 

    def run(self): 
     try: 
      self.running = True 
      reactor.add_after_stop_func(self.stop) 
      thread.start_new_thread(self._handle_cmds,()) 
      reactor.main() 
#   while(True): 
#    pass 
     except Exception, e: 
      print e 

    def _help(self): 
     help = 'commands: ' 
     for k in self.commands.keys(): 
      help += k + ', ' 
     print help[:-2] 

    def _handle_cmds(self): 
     try: 
      while self.running: 
       command = str(raw_input('>>>')) 
       try: 
        print command 
        self.commands[command]() 
       except KeyError: 
        print 'invalid command, try help' 
       command = '' 
     except Exception, e: 
      print e 

def main(): 
    print "Test Program\n" 
    cmdline = CommandLineCtrlPoint() 
    cmdline.run() 

if __name__ == "__main__": 
    main()

我發現了「錯誤」。該解決方案是替代的行:

command = str(raw_input('>>>')) 

通過

print '>>> ', 
command = sys.stdin.readline().replace('\n','') 

我不知道,但也許這樣做的原因可能是在這樣的解釋:

如果有人有另外一種解釋如果發表評論,我將不勝感激。
