Stack version

2.1.3.1 x86_64 hpack-0.31.2

Method of installation

Installed via Nix

Other details

If I set in the stack.yaml file: pure: false then the build fails with the issue mentioned in: #5008

[dbaynard]

@nh2 does anything spring to mind, here?

[qrilka]

@razvan-flavius-panda I don't quite remember all the internal details of Stack invocation with Nix but the main thing is that Stack reexecutes itself with needed dependencies set up by a nix-shell. In your log I see that 2nd invocation doesn't see that it gets reexecuted so it tries to go 1 more level deeper and fails because of a different $PATH in pure nix-shell session. Probably something in your code breaks this Stack mechanism e.g. by unsetting $STACK_IN_NIX_SHELL.

[PierreMardon]

Hi ! I'm trying to have the haskell tools installed and working same problem with context and actions:

• mac os 10.14.6 (18G87)
• followed haskell.org setup advices
  • executing ghcup sh : curl https://get-ghcup.haskell.org -sSf | sh
  • executing stack sh : curl -sSL https://get.haskellstack.org/ | sh
• I'm using zsh so I had to add source ~/.ghcup/env to ~/.zshrc
• tried to build an existing haskell project

and here are my logs:

EDIT: I'm a total beginner in haskell's world and have no clue for now how an env variable could be overwritten. I tried with sh btw, and have the exact same result.

[qrilka]

@PierreMardon your case looks to be different from what the orginal poster has. Regarding your log it would be good to answer some questions: what's the stack.yaml you're using? Do you use system GHC option with Stack (otherwise ghcup looks to be superfluous as Stack by default manages GHC installation by itself)? It looks like you enable Nix mode in Stack, isn't it? Is nix-shell available by default in your $PATH?

[akhesacaro-fretlink]

I add the same problem, just in case someone stumbles upon this issue.

You should add the --no-nix flag to your stack command if invoking stack within --pure nix-shell.

Also, you probably have to add the --system-ghc flag to your stack command, to tell it to take ghc from the nix-shell.
