安装ghc后,我改变了工作目录
:cd /newDirectory
为此,我得到警告:
Warning: changing directory causes all loaded modules to be unloaded,
because the search path has changed.
现在,我不能使用像Char这样的数据类型.对于这一行:
map Char.isLower "abcD"
我收到消息:
Failed to load interface for `Char'
It is a member of the hidden package `haskell98-2.0.0.2'.
Use -v to see a list of the files searched for.
目录的更改是否是该错误的原因？我该如何解决？
