I followed the instructions here http://www.euterpea.com for installing Euterpea (a domain-specific language for computer music applications embedded in Haskell), and I received a message that certain packages and things failed to install (see the code below). How can I install the remaining packages?
Mo-MacBook-Pro:~ Mo$ cabal update

It would be great if someone could help. Thanks.
I have included all the code, lest some particular relevant detail was omitted.
Edit
I have also tried to install Euterpea via stack. I get this message:
Mo-MacBook-Pro:~ Mo$ stack install Euterpea
Error: While constructing the build plan, the following exceptions were
encountered:
In the dependencies for Euterpea-2.0.6:
PortMidi must match ==0.1.6.1, but the stack configuration has no specified version (latest matching version is 0.1.6.1)
arrows must match >=0.4 && <0.5, but the stack configuration has no specified version (latest matching version is 0.4.4.2)
needed since Euterpea is a build target.
Some different approaches to resolving this:
* Consider trying 'stack solver', which uses the cabal-install solver to attempt to find some working build configuration. This can be convenient when dealing with many complicated constraint
errors, but results may be unpredictable.
* Recommended action: try adding the following to your extra-deps in /Users/Mo/.stack/global-project/stack.yaml:
- PortMidi-0.1.6.1
- arrows-0.4.4.2
Plan construction failed.
-- Edit 2.
As suggested below, I tried cabal install random-1.1 --force-reinstalls which generated:

Edit 3
It has been suggested below that multiple packages are botched and that I should try re-installing all of them (in a single command, i.e. cabal install random tf-random QuickCheck Euterpea --force-reinstalls.
However, if I write cabal install random tf-random QuickCheck Euterpea --force-reinstalls I receive the following code:

What can I do to install Euterpea?
Installing the Euterpea package
This answer uses LTS 12.26 as I've verified it works, but this should work for most LTS releases (see bottom of step 2 for details).
Make a new Stack project:
Edit
stack.yamland set the LTS to 12.26 andextra-depsto specify the versions of packages that aren't present in the LTS but are present on Hackage:The errors you were getting on the Stack install ("PortMidi must match ==0.1.6.1, but the stack configuration has no specified version") indicate that a package you're using requires a particular version of a library, but the package repository (LTS snapshot) doesn't contain that library, so you need to specify it explicitly. Stack then prints which library and version is missing, so you can just keep trying
stack buildand adding the libraries until the build succeeds.We use LTS 12.26 here, but by adding the
extra-depspackages as described above, you should be able to get it working on any LTS.Edit
package.yamland addEuterpeato the list of dependencies:A simple test in
app/Main.hs:Run
stack build:Running the executable produced by the project should emit a tone if you're running a MIDI synthesiser:
Troubleshooting
If you get an error like
*** Exception: No MIDI outputs!, then you're not running a MIDI synthesiser (see below). Make sure you run it in the background (eg. in another terminal).If you don't get an error but there's no audio output, try running
devicesin GHCI to see what outputs are available, and then useplayDev xinstead ofplay, wherexis the OutputDeviceID of the synth input port. Eg:If you run
devicesand don't see any synth input ports, but you have fluidsynth running in the background, then you might need to restartghciand try again.Running a MIDI synthesiser
Here's a quick step-by-step to get Fluidsynth running on Debian (with guesses at a Mac setup along the way).
Install fluidsynth: On Debian this is
sudo apt install fluidsynth, on mac it could bebrew install fluidsynth- there's quite a few articles on how to do this, just google it if in doubt.Run fluidsynth: On Debian using ALSA this is
Instructing fluidsynth to run in server mode, use
alsaas the audio driver andalsa_seqas the MIDI driver, and use the soundfontFluidR3_GM.sf2(should be installed as part of the fluidsynth install).On Mac, it seems like the correct commandline is:
If you can't find the
FluidR3_GM.sf2file then it's likely it's been installed in a different location. As a last resort, you can just download a soundfont file and use that rather than the one provided by FluidSynth.After running this, you should be given a prompt and maybe a few warnings, and fluidsynth will be running. Make sure it's running before using Euterpea, and keep it running while using Euterpea.
