今天我跟着Haskel平台网站下载版本8.2.1并成功安装它，我也添加了额外的路径。但是当我在开始菜单或PowerShell中打开GHCI时，它无法成功运行，下面是错误消息，ps：这是Windows 10 Pro Insider Preview，它重要还是什么？
GHCi, version 8.2.1: http://www.haskell.org/ghc/ :? for help
ghc.exe: internal error: mkPath failed converting char* to wchar_t*
(GHC version 8.2.1 for x86_64_unknown_mingw32)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
与此同时，winghci也无法正常运行，一旦打开，它就会关闭并报告问题。 你们之前遇到过这个问题吗？感谢大家的建议和解决方案！
