2 days stucked with this (running on Ubuntu):

[nix-shell:~/plutus-pioneer-program/code/week01]$ cabal build 
Warning: Requested index-state 2021-10-20T00:00:00Z is newer than 'hackage.haskell.org'! Falling back to older state (2021-10-19T23:39:06Z).
Resolving dependencies... cabal: Could not resolve dependencies:
[__0] trying: Win32-network-0.1.0.0 (user goal)
[__1] trying: base-4.14.1.0/installed-4.14.1.0 (dependency of Win32-network)
[__2] trying: lobemo-scribe-systemd-0.1.0.0 (user goal)
[__3] next goal: libsystemd-journal (dependency of lobemo-scribe-systemd)
[__3] rejecting: libsystemd-journal-1.4.5 (conflict: pkg-config package libsystemd>=209, not found in the pkg-config database)
[__3] rejecting: libsystemd-journal-1.4.4 (conflict: base==4.14.1.0/installed-4.14.1.0, libsystemd-journal => base>=4.6 && <4.13)
[__3] skipping: libsystemd-journal-1.4.3, libsystemd-journal-1.4.2, libsystemd-journal-1.4.1, libsystemd-journal-1.4.0, libsystemd-journal-1.3.4, libsystemd-journal-1.3.3, libsystemd-journal-1.3.1, libsystemd-journal-1.3.0, libsystemd-journal-1.2.0, libsystemd-journal-1.1.0, libsystemd-journal-1.0.0 (has the same characteristics that caused the previous version to fail: excludes 'base' version 4.14.1.0)
[__3] fail (backjumping, conflict set: base, libsystemd-journal, lobemo-scribe-systemd) After searching the rest of the dependency tree exhaustively, these were the goals I've had most trouble fulfilling: base, libsystemd-journal, lobemo-scribe-systemd, Win32-network Try running with --minimize-conflict-set to improve the error message.

  • In my case, I needed to put a base dependency version constraint in my cabal file: base ^>=4.14.1.0.

I received this error when running nix-shell from the plutus repository. To fix I exited that nix-shell, navigated to plutus-apps repository, and checked out the appropriate hash from the cabal.project file found in the cabal.project file. Then ran nix-shell from plutus-apps instead of plutus.

source-repository-package
  type: git
  location: https://github.com/input-output-hk/plutus-apps.git
  tag: 41149926c108c71831cfe8d244c83b0ee4bf5c8a
  1. $> cd <projects-dir>/plutus-apps
  2. $> git checkout 41149926c108c71831cfe8d244c83b0ee4bf5c8a
  3. $> nix-shell
  4. $> cd ../plutus-pioneer-program/code/week01
  5. $> cabal repl

the coresponding version for you can find there

$cd ~/code/haskell/plutus-pioneer-program/code/week01/ $less cabal.project

and there is a tag with right version
