cabal install hedis
由于其依赖性而失败 - bytestring-lexing
未安装。错误消息是,
bytestring-lexing-0.4.3.2 failed during the configure step. The exception was:
ExitFailure 1
hedis-0.6.5 depends on bytestring-lexing-0.4.3.2 which failed to install.
为了说明此软件包失败的原因,我使用此命令对bytestring-lexing
的本地安装进行了grep-ed,
ghc-pkg field bytestring-lexing depends
但是没有本地包,
ghc-pkg: cannot find package bytestring-lexing
现在不是版本冲突,还有什么可能导致此错误?
答案 0 :(得分:0)
错误消息只是表明它无法找到包bytestring-lexing
。所以首先尝试安装该软件包:
cabal install bytestring-lexing
然后再次尝试安装hedis
。
