知道哪里出了问题以及如何修复吗?文本转换软件包与本周发布的最新版本的base16 bytestring
不兼容。所以构建失败了
短期解决方案是添加一个约束,在cabal install
命令中使用标志--constraint=“base16 bytestring<1”
,或者在文件~/.cabal/config
中添加行约束:base16 bytestring<1
。()
从长远来看,必须修复文本转换
包,以便在依赖项base16 bytestring<1
上添加版本上限。您可以在以下问题中询问事物的状态:
理想情况下(不一定),应发布与base16-bytestring-1.0.0.0
兼容的文本转换的新版本,但是仍然有必要修正现有版本的界限,以避免出现任何损坏的构建计划。文本转换
