当我使用外部导入运行我的文件时，我发现了这个错误。
ByteCodeLink: can't find label
During interactive linking, GHCi couldn't find the following symbol:
richards
This may be due to you not asking GHCi to load extra object files,
archives or DLLs needed by your current session. Restart GHCi, specifying
the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.
Alternatively, this link failure might indicate a bug in GHCi.
If you suspect the latter, please send a bug report to:
glasgow-haskell-bugs@haskell.org
创建一个.cabal文件并从那里加载到GHCi后，我仍然会收到此错误。 有什么想法吗？
