antlr4:ATN版本2预计为3 [英] antlr4: ATN version 2 expected 3

问题描述

当尝试使用生成的语法和词法分析器时，我得到:

When trying to use a generated grammar and lexer I get:

org.antlr.v4.runtime.atn.ATN;无法对版本2(预期为3)的ATN进行反序列化.

org.antlr.v4.runtime.atn.ATN; Could not deserialize ATN with version 2 (expected 3).

怎么了?

推荐答案

您的解析器是使用ANTLR 4.0生成的，但是您尝试使用ANTLR 4.1执行它.造成这种情况的最可能原因是使用ANTLRWorks 2.0生成了内部使用ANTLR 4.0的解析器.我正在发布ANTLRWorks 2.1，可以纠正这种不匹配.

Your parser was generated with ANTLR 4.0, but you are trying to execute it with ANTLR 4.1. The most likely cause of this is using ANTLRWorks 2.0 to generate the parser, which internally uses ANTLR 4.0. I'm in the process of releasing ANTLRWorks 2.1 which will correct this mismatch.
