Upgrading a library doesn't work

[yaxu]

Trying to install a new version of a library causes a dependency error:

alex@toaster:~$ cabal --version
cabal-install version 3.6.2.0
compiled using version 3.6.2.0 of the Cabal library 
alex@toaster:~$ cabal install tidal-1.7.10 --lib

Ah I see this is a duplicate of the well articulated #7373 which is closed in favour of the more obscure (to me) #5559.

[fendor]

Hi!

The workflow for cabal install --lib is somewhat lacking and you shouldn't use it in general, unless you take extra caution.

To unblock you immediately, you can take a look at ~/.ghc/x86_64-linux-8.10.7/environments/default and either remove the line that mentions or tidal, or delete that file entirely. The latter is probably the better approach.

[yaxu]

Thanks @fendor, I'm a developer of the tidal package and familiar with workarounds that I've been helping people with since the switch to v2- commands some years ago. It would be great if there was a reliable way to install, use and upgrade a library with cabal that didn't require difficult workarounds.

[yaxu]

Also a duplicate of #6394 and #6391! (apologies for the duplication, it's been a while..)

[jneira]

so let's closing it as duplicate, @yaxu don't worry and thanks for reporting your struggles with cabal v2 workflow
