I am trying to install reflex
and reflex-dom
using cabal install
I got the following error messages:
$ cabal install reflex-dom
...
cabal: The following packages are likely to be broken by the reinstalls:
lens-4.15.1
ghcjs-0.2.0
free-4.12.4
kan-extensions-5.0.1
adjunctions-4.3
Use --force-reinstalls if you want to install anyway.
ghcjs
on GitHub is at 0.2.0 on the "master" branch and 0.2.1 on a branch called "dedupe". And I am also scared of breaking lens
. Is there any way to install reflex
and reflex-dom
in a consistant way? Maybe I need to change the .cabal
file
$ cabal install reflex-dom

The best way that I know of to install reflex and reflex-dom (and ghcjs too) in a consistent way on a linux environment is to follow the setup instructions on the reflex-platform readme .
The process amounts to cloning the reflex-platform repository and running a script, "try-reflex" from inside that repository. The try-reflex script starts a shell from which you can run ghcjs will full access to reflex/reflex-dom . This shell environment is independent of what you previously installed on your computer so you don't have to worry about messing up lenses or any other cabal package you already have in place.
