5 years ago @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.

5 years ago Hi ! I'm trying to have the haskell tools installed and working same problem with context and actions:
curl https://get-ghcup.haskell.org -sSf | shcurl -sSL https://get.haskellstack.org/ | shsource ~/.ghcup/env to ~/.zshrcand here are my logs:

I tried with sh btw, and have the exact same result.

5 years ago @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?

3 years ago 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.
Steps to reproduce
stack buildin project rootExpected
Build to succeed.
Actual
What actually happened.
Stack version
Method of installation
Installed via Nix
Other details
If I set in the
stack.yamlfile:pure: falsethen the build fails with the issue mentioned in: https://github.com/commercialhaskell/stack/issues/5008
