mysterious unwanted user goal being added to my new-install targets

[claudeha]

Previously I was hacking on grenade, using cabal v1-install. Now i switch to an unrelated project, et, and cabal new-install fails mysteriously, trying and failing to install grenade.

claude@eiskaffee:~/code/code.mathr.co.uk/et$ cabal new-install et.cabal
Wrote tarball sdist to
/home/claude/code/code.mathr.co.uk/et/dist-newstyle/sdist/et-0.tar.gz

[__1] rejecting: grenade-0.1.0 (conflict:

[__1] fail (backjumping, conflict set: containers, grenade)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: containers, grenade

AFAIK et does not depend (even indirectly) upon grenade.

I have tried to wipe all traces of grenade from ~/.cabal, but have not quite succeeded:

I am using ghc-8.6.3.

Do you perhaps have a package-env lying around somewhere? https://downloads.haskell.org/~ghc/master/users-guide/packages.html#package-environments

[claudeha]

Yes! that was it! ~/.ghc/x86_64-linux-8.6.3/environments/default had grenade listed (twice). I didn't edit that file by hand, I don't know how it was created. Removing the 2 offending lines and cabal resolved my dependencies and is compiling now. Thanks!

[gbaz]

new install of a lib adds to the default environment file.

[claudeha]

there may be some issues with that, as i had the same grenade-0.1.0 line twice with different hashes...

[gbaz]

should be resolved by https://github.com/haskell/cabal/issues/6481

I'm closing optimistically. Please report in a new ticket (citing this ticket number), if the problem happens again.
