当我尝试使用Carthage添加依赖项时，出现此错误

with your_table (N, tag1, tag2, tag3, tag4, tag5, tag6,
  fieldiftag1_1, fieldiftag2_1, fieldiftag3_1, fieldiftag4_1, fieldiftag5_1, fieldiftag6_1,
  fieldiftag1_2, fieldiftag2_2, fieldiftag3_2, fieldiftag4_2, fieldiftag5_2, fieldiftag6_2)
as (
            select 1, 'y', 'y', 'y', 'n', 'n', 'n',
              'text1_1', 'text2_1', 'text3_1', null, null, null,
              'text1_2', 'text2_2', 'text3_2', null, null, null
            from dual
  union all select 2, 'n', 'y', 'n', 'y', 'n', 'n',
              null, 'text2_1', null, 'text4_1', null, null,
              null, 'text2_2', null, 'text4_2', null, null
            from dual
)
select n, text_1, text_2
from your_table
unpivot((flag, text_1, text_2) for tag in (
  (tag1, fieldiftag1_1, fieldiftag1_2),
  (tag2, fieldiftag2_1, fieldiftag2_2),
  (tag3, fieldiftag3_1, fieldiftag3_2),
  (tag4, fieldiftag4_1, fieldiftag4_2),
  (tag5, fieldiftag5_1, fieldiftag5_2),
  (tag5, fieldiftag6_1, fieldiftag6_2)
))
where flag = 'y';

         N TEXT_1  TEXT_2 
---------- ------- -------
         1 text1_1 text1_2
         1 text2_1 text2_2
         1 text3_1 text3_2
         2 text2_1 text2_2
         2 text4_1 text4_2
