I am following https://docs.plutus-community.com/docs/setup/MacOS.html

I know the plutus-apps repo is newer than those docs and have downloaded it but it seems I can't build plutus-pab.

When I run

$ nix-build -A plutus-pab

I get:

error: attribute 'plutus-pab' in selection path 'plutus-pab' not found

I thought I had built everything but when I tried to run $ npm run start in plutus-playground-client I got this:

sh: line 1: plutus-playground-generate-purs: command not found

  • I may need to build github.com/input-output-hk/plutus-apps/tree/main/… but when i try $ nix-build ../default.nix -A plutus-apps.haskell.packages.plutus-pab I get Segmentation fault: 11

  • Was able to run $nix-build default.nix -A plutus-apps.haskell.packages.plutus-pab from within nix-shell. Seems like it worked, but main problem still not resolved.

  • After a reboot, this issue seems to have resolved itself. Unfortunately I'm not sure what I did. Playground client now runs, though I cannot compile the hello world sample. On to tackling next error...
