    \_open = file  
NameError: name 'file' is not defined  
 这个问题是因为twisted不支持Python3的原因  
 Python3没有file内建方法用open来代替  
 python2x(file(filename\[, mode\[, bufsize\]\]) When opening a file, it’s preferable to use open() instead of  
  
invoking this constructor directly. file is more suited to type testing (for example, writing isinstance(f,  
  
file)).)  
  
解决这个问题: 将 \_open = file 改为：try:  
                    \_open = file  
                    except:  
                    \_open = open  
  
During handling of the above exception, another exception occurred:

做了上面的更改时出现下面问题

ImportError: No module named 'sgmllib'  
sgmllib是2.6以后引入python，在3.0以后这个库被移除了。如果你的python版本<2.6或者>=3.0就找不到这个module。  
如果你要使用已有的、依赖sgmllib的代码，安装python2.7等合适的版本。如果要迁移到3.0环境，需要移植代码，可以使用  
  
html.parser.HTMLParser  
  
解决：\# from sgmllib import SGMLParser 注释掉  
      from html.parser import HTMLParser as SGMLParser  
another: try:  
             from sgmllib import SGMLParser  
    except:  
         from html.parser import HTMLParser as SGMLParser  
  
  
又是版本问题
