antlr4:ATN 版本 2 预期为 3 [英] antlr4: ATN version 2 expected 3

问题描述

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;无法使用版本 2(预期为 3)反序列化 ATN.

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，但您正尝试使用 ANTLR 4.1 执行它.最可能的原因是使用 ANTLRWorks 2.0 生成解析器，该解析器在内部使用 ANTLR 4.0.我正在发布 ANTLRWorks 2.1，它将纠正这种不匹配.

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.
