Unused import: twisted，错误，我装了twisted

/usr/lib/python2.6/site-packages/Twisted-11.1.0_r33371-py2.6-linux-i686.egg
我是原码安装，但还是说找不到

终端测试正常，没有报错

OK

eclipse运行是这样 我直接在命令行运行 python server.py则

# python server.py
Running Socket AMF gateway on localhost:8000
Running Policy file server on localhost:843

看似没有问题啊

刚我打印了一下
print(__name__)
if(__name__=="__main__"):
    __name="__main__"

eclipse 的是两次都是server
命令行的是一次server 一次__main__，应该是eclipse设置又问题把，要如何调整？

断点发现一执行(opt, args) = parser.parse_args()这个语句，就跳到头部重新执行一便了，如果没这个语句好像就只执行一遍

我把__name__强制赋值__name__="__main__",断点执行一次，这是下面的第一次错误内容
pydev debugger: starting
Finding files... done.
Importing test modules ... __main__
Usage: runfiles.py [options]

runfiles.py: error: no such option: --port


下面是全部的
pydev debugger: starting
Finding files... done.
Importing test modules ... __main__
Usage: runfiles.py [options]

runfiles.py: error: no such option: --port
__main__    这里又打印了，说名又执行了一次，但这次调用parse_args没有返回到最头部重新执行，而是继续到底了
Usage: runfiles.py [options]

从结果看，好像是eclipse传递给程序的参数不全，或者是参数不正确，但我在eclipse里也没发现哪里又设置的呀，在说在终端python server.py
这样执行也没传入参数呢
望大侠讲解下他的执行过程

jd808

换了个文件名，就可以正常的传递__main__参数了，只执行一次了
换了端口，错误也补报了，正常了，兄弟们，吸取教训啊，原来文件名也回导致问题的哈，端口冲突也会导致问题哈，但就是补报错误哈哈

文件名不能和系统的文件有同样的名字，否则就相当于覆盖了
