我是Bison的新人。 我已经制作了我的.y文件但是在编译中我收到了这个错误：
警告：42次/减少冲突[-Wconflicts-sr]
我已经打开了生成的.output文件，我已经看到了以下内容，但无法理解，无法找出问题所在。
以下是我的.output文件的一部分：

这是我的声明部分：

这是我在野牛的规则：

告诉您在此状态下，在前瞻符号'+' shift, and go to state 87
'-' shift, and go to state 88
'+' [reduce using rule 56 (expr_decl)]
'-' [reduce using rule 56 (expr_decl)]
和'+'上有两个移位/减少冲突。 reduce操作周围的'-' .. [表示该操作已被删除（解决冲突有利于转移）。
消息：
]告诉您有关语法中优先规则解决的转移/减少冲突（因此不包含在警告中的42个转换/减少冲突中）。
优先规则不能解决Conflict between rule 56 and token KW_OR resolved as reduce (KW_OR < KW_NOT).
