SocketServer没有模块正在导入

Question

我想在我的mac上创建一个SocketServer。

然而，它似乎与包的一些问题。当我尝试找到here这个采样代码时，它会引发属性错误。

import SocketServer 

class MyTCPHandler(SocketServer.BaseRequestHandler): 
    """ 
    The RequestHandler class for our server. 

    It is instantiated once per connection to the server, and must 
    override the handle() method to implement communication to the 
    client. 
    """ 

    def handle(self): 
     # self.request is the TCP socket connected to the client 
     self.data = self.request.recv(1024).strip() 
     print "{} wrote:".format(self.client_address[0]) 
     print self.data 
     # just send back the same data, but upper-cased 
     self.request.sendall(self.data.upper()) 

if __name__ == "__main__": 
    HOST, PORT = "localhost", 9999 

    # Create the server, binding to localhost on port 9999 
    server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler) 

    # Activate the server; this will keep running until you 
    # interrupt the program with Ctrl-C 
    server.serve_forever() 

错误：

Traceback (most recent call last): 
    File "/Users/ddl449/Projects/visualization/SocketServer.py", line 1, in <module> 
    import SocketServer 
    File "/Users/ddl449/Projects/visualization/SocketServer.py", line 3, in <module> 
    class MyTCPHandler(SocketServer.BaseRequestHandler): 
AttributeError: 'module' object has no attribute 'BaseRequestHandler' 

我不知道是否有这样做，我在Mac上运行。我的蟒蛇版本是：

2.7.5 (v2.7.5:ab05e7dd2788, May 13 2013, 13:18:45) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]

好像你有SocketServer.py python路径中的某处。

检查使用以下命令：

python -c "import SocketServer; print(SocketServer.__file__)" 

重命名该文件将解决你的问题。

UPDATE

重命名文件/Users/ddl449/Projects/visualization/SocketServer.py。如果有/Users/ddl449/Projects/visualization/SocketServer.pyc，请删除该文件。
