在python2.6上使用python蜻蜓python2.6问题

Question

我正在玩python中的Dragonfly lib。我正在使用Windows7 + python2.6。然而，当我尝试运行演示代码（这是从蜻蜓为例）

from dragonfly.all import Grammar, CompoundRule 

# Voice command rule combining spoken form and recognition processing. 
class ExampleRule(CompoundRule): 
    spec = "do something computer"     # Spoken form of command. 
    def _process_recognition(self, node, extras): # Callback when command is spoken. 
     print "Voice command spoken." 

# Create a grammar which contains and loads the command rule. 
grammar = Grammar("example grammar")    # Create a grammar to contain the command rule. 
grammar.add_rule(ExampleRule())      # Add the command rule to the grammar. 
grammar.load()          # Load the grammar. 

我收到以下错误：

Traceback (most recent call last): 
    File "test.py", line 2, in <module> 
    from dragonfly.all import Grammar, CompoundRule 
ImportError: No module named all 

我怎样才能解决呢？

Answer 1

摆脱.all。这个例子似乎已经过时了。它应该看起来像这样：

from dragonfly import Grammar, CompoundRule
