Strictly speaking, the second option (specifying the sandbox as the user db) is a more correct match with what cabal-install does.<br><br>On Friday, August 4, 2017, Emil Axelsson <<a href="mailto:78emil@gmail.com">78emil@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Den 2017-08-04 kl. 19:33, skrev Daniel Trstenjak:<br>

Ah, I see. I still don't understand what went wrong in this particular case,<br>
but at least it makes sense that there's a difference between `-package-db`<br>
and `cabal exec`.<br>

<br>
can you please test if `cabal-cargs` behaves in the same way as `cabal exec`<br>
if you add a `-no-user-package-db` or/and replace `-packabe-db` by `-user-package-db`.<br>

<br>
Yes! `-no-user-package-db` does the trick.<br>
<br>
I have to admit I had forgotten completely about the user DB. When running `cabal sandbox hc-pkg list` I only see the global one and the one in the sandbox. But `ghc-pkg` shows the user DB and indeed it contains `hashable-1.2.6.1` which was causing me trouble.<br>
<br>
Cool, problem solved.<br>
<br>
Would it make sense then for `cabal-cargs` to always emit `-no-user-package-db` when it discovers a sandbox?<br>
<br>
Cheers<br>
