樹莓派上的GPS守護進程

Question

我正在嘗試實施一個示例腳本，adafruit爲他們設計的覆盆子pi的gps單元之一提供。代碼如下：

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

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" 

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

所以我將「＃！/ usr/bin/python -tt」添加到「gps.py」文件的頂部，然後「chmod u + x /home/pi/gps.py」

運行此操作時，我收到以下錯誤，但我不明白爲什麼：

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

pi@raspberrypi ~ $ /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 

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

嘗試重命名你的腳本比gps.py.其他的東西Python解釋器試圖導入它，而不是位於系統庫中的gps.py腳本。
