在python2.6上使用python蜻蜓python2.6問題

Question

我正在玩python中的Dragonfly lib。我正在使用Windows7 + python2.6。然而，當我嘗試運行演示代碼（這是從蜻蜓爲例）

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. 

我收到以下錯誤：

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

我怎樣才能解決呢？

Answer 1

擺脫.all。這個例子似乎已經過時了。它應該看起來像這樣：

from dragonfly import Grammar, CompoundRule
