我尝试使用ghc-7.8.2安装lambdabot
,但在安装haskell-src-exts
时遇到错误。为了诊断问题,我尝试了
cabal install haskell-src-exts -v3
并收到以下错误。我使用的是Windows XP 64位。我不知道这是否与windows目录名中的空格有关。任何想法/指针如何解决问题?

答案 0 :(得分:7)
我明白了。我试图找到日志文件作为评论建议。但是,在cabal / log文件夹中,在新的ghc-7.8安装上running cabal-install lambdabot
之后,哈希表和haskline只有两个日志文件。
要查看此错误是否与默认cabal目录中的空格有关,我使用了一个没有空格的文件夹并进行了手动安装:
$ cd /d/temp
$ cabal get haskell-src-exts
Unpacking to haskell-src-exts-1.15.0.1\
$ cd haskell-src-exts-1.15.0.1/ && cabal configure

setup.exe: The program 'happy' version >=1.17 is required but it could not be
found.
因此,依赖项中的happy
以某种方式丢失并且未被cabal检测到。结果happy
使用默认的cabal install
命令也存在问题,可以通过手动安装来解决,例如/d/temp
,
cabal get happy && cd happy* && cabal configure && cabal install
这将安装happy
并对haskell-src-exts
执行相同操作正确安装软件包。但是在安装lambdabot的过程中还有其他错误,其中没有一个似乎与haskell-src-exts和happy一起遇到的错误。
