A reminder:

When I wanted to upgrade to yi 0.4.6.2, I needed to download the new package list

cabal update #download list of new packages cabal upgrade #make any upgrades

Note that 'cabal upgrade' upgrades everything you've currently got installed (which in general is not necessarily possible).

The standard workflow is just:

cabal update #download list of new packages cabal install yi #install latest version of yi

$ cabal install yi Resolving dependencies... 'yi-0.4.6.2' is cached. Configuring yi-0.4.6.2... cabal: alex version >=2.0.1 && <3 is required but it could not be found. cabal: Error: some packages failed to install: yi-0.4.6.2 failed during the configure step. The exception was: exit: ExitFailure 1

$ cabal install yi-gtk Resolving dependencies... cabal: cannot configure yi-gtk-0.2.1. It requires sourceview >=0.9.11 There is no available version of sourceview that satisfies >=0.9.11

Trying cabal upgrade didn't fix it - it still throws the same error.

Yi fails on Alex because Cabal doesn't track executables, nor executables needed for installation. You want 'cabal install alex yi'; I believe the FAQ covers this. As for cabal install yi-gtk, unless things have changed since I last looked, the answer is Don't Do That. yi-gtk and yi-vty are solely for yi 0.3 and below - it's obsolete, in other words. Yi depends directly on vty (which cabal install will handle) and GTK2HS, which unfortunately is not on Hackage and so you or your distro has to handle that. -- gwern beef Croatian Waco, Mace H
