Question

看起来3.5.1是最新的3.x版本，而3.1.3是唯一可用的版本（http://www.antlr.org/download/Python/）。但是，当我尝试使用该示例运行解析器时，我得到的投诉是我的运行时版本与我的ANTLR版本不兼容：

$ PYTHONPATH=/home/dustin/build/antlr3/antlr_python_runtime-3.1.3 python SimpleCalcParser.py /tmp/lang 
Traceback (most recent call last):
  File "SimpleCalcParser.py", line 231, in <module>
    main(sys.argv)
  File "SimpleCalcParser.py", line 220, in main
    lexer = SimpleCalcLexer(char_stream)
  File "/home/dustin/development/antlr/antlr3/hello_world_python/SimpleCalcLexer.py", line 31, in __init__
    super(SimpleCalcLexer, self).__init__(input, state)
  File "/home/dustin/build/antlr3/antlr_python_runtime-3.1.3/antlr3/recognizers.py", line 1072, in __init__
    BaseRecognizer.__init__(self, state)
  File "/home/dustin/build/antlr3/antlr_python_runtime-3.1.3/antlr3/recognizers.py", line 184, in __init__
    self.antlr_version_str))
RuntimeError: ANTLR version mismatch: The recognizer has been generated by V3.0.1, but this runtime is V3.1.3. Please use the V3.0.1 runtime.

有人能把我放在正确的道路上吗？由于可供下载的版本稀缺，我似乎无法做很多事情。

如果你想使用Python运行时，必须使用ANTLR 3.1.3来生成[Python]词法分析器和解析器。

在此处下载3.1.3：http://www.antlr3.org/download/antlr-3.1.3.jar

以下Q＆amp; A提供了一个有效的Python示例：ANTLR parsing MismatchedTokenException

带有Python运行时3.1.3的ANTLR 3.5.1（最新3.x版本）（仅适用于Python运行时）
