Could not find module ‘System.Directory’ although package present @ build-depends in .cabal file.
(Not sure but this might be related to #941 #897)

You could clone minimal project that reproduces the issue and a bit more info here.
(I was able to reproduce this on OS X & linux.)

Steps to reproduce:

  1. Create new project with stack new stack-directory-problem
  2. Add directory to build-depends in stack-directory-problem.cabal
  3. Add import System.Directory somewhere in the code.
  4. Run command stack build.

Expected:
Stack builds project successfully.

Actual:

Could not find module ‘System.Directory’
It is a member of the hidden package ‘directory-1.2.2.0@direc_0hFG6ZxK1nk4zsyOqbNHfm’.
Perhaps you need to add ‘directory’ to the build-depends in your .cabal file.

Here is the stack --version output:

$ stack --version
Version 1.1.2 x86_64 hpack-0.14.1```

Here is the command I ran with --verbose

$ stack build --verbose
Version 1.1.2 x86_64 hpack-0.14.1

Could it be that you forgot to add directory to the build-depends of the executable section?

You're right. My bad.
Thank you for the answer and sorry for the noise.

No worries! :)

Let me use this occasion to plug https://github.com/sol/hpack, an alternative, Cabal-compatible package metadata format, where you can define common dependencies that will apply to all the package sections. This reduces the amount of editing that you have to do to add a dependency and helps you avoid simple mistakes like this one! :)

Why do we need to add package manually to build-depends? shouldn't it be added when installing package by stack install directory.
