我写了一个简单的模块叫做Test:

module Test (main) where

main =
  putStrLn "Hello"

但是,当我尝试通过以下命令行编译它时:

ghc Test.hs -o my-program

我收到以下错误:

[1 of 1] Compiling Test             ( Test.hs, Test.o )

<no location info>: error:
    output was redirected with -o, but no output will be generated because there is no Main module.
