具有以下项目结构:

src/FirstExecutable.hs
src/SecondExecutable.hs
my-amazing-project.cabal

和以下cabal设置:

name:               my-amazing-project

cabal-version:      >=1.8

  main-is:          FirstExecutable.hs
  ghc-options:      -O2 -threaded -with-rtsopts=-N
  build-depends:    base == 4.5.*

executable second-executable
  hs-source-dirs:   src
  main-is:          SecondExecutable.hs
  ghc-options:      -O2 -threaded -with-rtsopts=-N
  build-depends:    base == 4.5.*

cabal install使用以下输出运行失败:
