haskell - 多个文件使用相同的模块名称 :

Question

当我输入 stack run 时，我没有收到错误消息，但是当我输入 stack ghci 时，我收到关于多个文件使用相同名称的错误，我该如何解决？

(base) wejden@wejdenaydi:~/wejden$ stack ghci
Using main module: 1. Package `wejden' component wejden:exe:wejden-exe with main-is file: /home/wejden/wejden/app/Main.hs

对于那些像我一样需要非常具体的说明的人，这里是:

executables:        
  mypkgname-exe:        
    main:                Main.hs        
    source-dirs:         app        
    ghc-options:        
    - -threaded        
    - -rtsopts        
    - -with-rtsopts=-N        
    dependencies:        
    - stocks        
    when:        
    - condition: false        
      other-modules: Paths_mypkgname

在哪里 mypkgname需要替换为您的包名。我发布这个是因为在我第一次尝试时我把 when条款在错误的地方。
