我正在尝试实施一个示例脚本,adafruit为他们设计的覆盆子pi的gps单元之一提供。代码如下:树莓派上的GPS守护进程

==============

import gps 

    # Listen on port 2947 (gpsd) of localhost 
    session = gps.gps("localhost", "2947") 
    session.stream(gps.WATCH_ENABLE | gps.WATCH_NEWSTYLE) 

    while True: 
     try: 
      report = session.next() 
      # Wait for a 'TPV' report and display the current time 
      # To see all report data, uncomment the line below 
      # print report 
      if report['class'] == 'TPV': 
     if hasattr(report, 'time'): 
      print report.time 
     except KeyError: 
      pass 
     except KeyboardInterrupt: 
      quit() 
     except StopIteration: 
      session = None 
      print "GPSD has terminated" 

==============

所以我将“#!/ usr/bin/python -tt”添加到“gps.py”文件的顶部,然后“chmod u + x /home/pi/gps.py”

运行此操作时,我收到以下错误,但我不明白为什么:

==============

[email protected] ~ $ /home/pi/gps.py 
    Traceback (most recent call last): 
     File "/home/pi/gps.py", line 2, in <module> 
     import gps 
     File "/home/pi/gps.py", line 5, in <module> 
     session = gps.gps("localhost", "2947") 
    TypeError: 'module' object is not callable 

==============

尝试重命名你的脚本比gps.py.其他的东西Python解释器试图导入它,而不是位于系统库中的gps.py脚本。
