I've run into the same error for two unrelated packages now, missingpy and monadiccp.

For missingpy, ghc will work if the -package-id random... is changed to the correct version, but I don't know how to install it after that.
Any workarounds would be much appreciated. I deleted all of ~/.cabal and ~/.ghc, but no luck.
additional info
ghc info is here, [ http://pastebin.com/jk40VPgw ]. This is my SuSE machine, where I built ghc 7.0.4 from source using ghc 6.12, as well as the latest Haskell Platform. (which was made for ghc 7.0.3, but I think that's okay).
also tried this on another machine [ http://pastebin.com/Digntv4K ]. that one had the Haskell Platform installed via system packages I think.
Have you tried cabal-dev? It's probably best if you start from a clean system, install only the Haskell Platform, and then use cabal-dev to sandbox each codebase you're using.

I recently read about FRP and became interested in Yampa. Because I have already installed it, here I just check its installation. When I follow the instructions
$ cabal sandbox init # Optional, but recommended
$ cabal update
$ cabal install Yampa
The result of the third step is:
cabal install Yampa

Warning: You asked to install executables, but there are no executables in
target: Yampa. Perhaps you want to use --lib to install libraries instead.
So I add --lib and get:

Then I turned to Vscode and write a line:

What I get is:

<no location info>: error: module ‘Yampa’ cannot be found locally
I've been trying to solve this problem but there seems to be no questions related to my situation. So I really need your help. Thanks!
--------------------------------------------------------update_2020_05_03------------------------------------------------
The file was directly created (without using "stack new "). That means, I just create a text file, put a line "import FRP.Yampa" and change its name to helloworld.hs in a folder "haskell_code" in VScode.
However, if I use "stack new mystic" to create a project called mystic. and go to its main.hs. I still cannot find FRP.Yampa. This time the error message when I run it is a little different:
error:
Could not load module ‘FRP.Yampa’
It is a member of the hidden package ‘Yampa-0.13.1’.
You can run ‘:set -package Yampa’ to expose it.
(Note: this unloads all the modules in the current scope.)
Use -v (or `:set -v` in ghci) to see a list of the files searched for.

4 | import FRP.Yampa
Therefore, I modified the mystic.cabal file by adding Yampa to its build-depends (I didn't use ‘:set -package Yampa’ because every time I have to input that things)
I got the following information:
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for mystic-0.1.0.0:
Yampa needed, but the stack configuration has no specified version (latest matching version
is 0.13.1)
needed since mystic is a build target.
Some different approaches to resolving this:
* Recommended action: try adding the following to your extra-deps
in /Users/zhangkai/mystic/stack.yaml:
- Yampa-0.13.1#sha256:4612a2646c27bcd3ac55c90dbc34249303e28aa5b3bc3e0c6fa9ce58b889843c,5436
Error: Plan construction failed.
Warning: Build failed, but trying to launch GHCi anyway
The following GHC options are incompatible with GHCi and have not been passed to it: -threaded
Configuring GHCi with the following packages: mystic
GHCi, version 8.8.3: https://www.haskell.org/ghc/ :? for help
<command line>: cannot satisfy -package Yampa
(use -v for more information)
And I took its advice by adding the line to the extra-deps of stack.yaml
extra-deps:
- Yampa-0.13.1#sha256:4612a2646c27bcd3ac55c90dbc34249303e28aa5b3bc3e0c6fa9ce58b889843c,5436
It works. Also I tried some other packages. If I create a single .hs file, I fail. If I create a project and modify its .cabal and .yaml, it works. I guess perhaps it has something to do with the environment. Those packages are downloaded but hidden.
So my question here would be: is there any workaround that allows the packages to be seen by even a single .hs file (Obviously it has neither .cabal nor .yaml)?
My program consists of 4 executables, and basically zero library code. My tests work by running the executables with various input files.
"stack test --coverage" apparently doesn't handle executables. OK, fine, but I can't figure out how to do it "by hand", as it were.
I've tried adding -fhpc to my cabal files, and it appears to work:

Well, I kind of left it for a while, and came back to it now. It worked for some reason. The only thing I can think of is that I upgraded from GHC 7.8.3 to 7.8.4. If anyone comes up with this again, try a different version of GHC.

I've done other various thing in my attempt to get my program to compile, but nothing has worked. I'd really like to just delete everything, go back to square one and download the package again. How can I do that?
Edit: further investigation shows that there might be 2 versions of Data.Vector: 0.10.0.1 and 0.9.1, maybe they are conflicting somehow?
Edit: ghc-pkg check lists no errors, but gives me a ton of warnings that look like this:
Warning: haddock-interfaces: /Users/drewgross/.cabal/share/doc/haskell-lexer-1.0/html/haskell-lexer.haddock doesn't exist or isn't a file

I did cabal install -v lens and obviously there was a ton of output but I think this is the relevant part:

Edit: ghc-pkg dump
Drews-MacBook-Pro:Blokus-AI drewgross$ ghc-pkg dump | grep "id: base"
id: base-4.5.1.0-81d626fb996bc7e140a3fd4481b338cd
Your package database is badly broken. The ghc -v output lists ten unusable packages due to missing or recursive dependencies, among them vector:
package vector-0.10.0.1-3450daae3d9f2092020075d05481123c is unusable due to missing or recursive dependencies:
base-4.5.1.0-81d626fb996bc7e140a3fd4481b338cd primitive-0.5.0.1-15cdc8c11a54a78809b647af0c2975b3
One thing all the broken packages have in common is the missing(?) dependency
base-4.5.1.0-81d626fb996bc7e140a3fd4481b338cd
where the
wired-in package base mapped to base-4.5.1.0-47f48c3ae7f8256a66a23e9dfe22eefc
used base has a different hash.
I'm not sure how this came about, as far as I'm aware, it's impossible to reinstall base, but it looks like you have two exemplars of ghc-7.4.2, and they step on each other's toes.
ghc-pkg list uses
/Library/Frameworks/GHC.framework/Versions/7.4.2-x86_64/usr/lib/ghc-7.4.2/package.conf.d
for the global package database, while the compilation uses
Using binary package database: /usr/local/Cellar/ghc/7.4.2/lib/ghc-7.4.2/package.conf.d/package.cache
Now, it might be that at least one of the two is a symlink and they're both pointing to the same place - then your package.cache is out of sync - but
Glasgow Haskell Compiler, Version 7.4.2, stage 2 booted by GHC version 7.4.2
a GHC booted by the same version seems unusual.
Can you ascertain whether you have indeed two ghc-7.4.2 and the command line uses a different one from the one cabal uses? which ghc tells you which one the shell uses, and cabal install -v some-package outputs the command line cabal uses, including the whole path to the used GHC.
You can list your installed packages with ghc-pkg list. For example (apparently I need to update),
$ ghc-pkg list | grep vector
vector-0.9.1
vector-algorithms-0.5.4
vector-algorithms-0.5.4.2
vector-space-0.8.0
vector-strategies-0.3
You can unregister them using ghc-pkg unregister. Ex,
$ ghc-pkg unregister vector-0.9.1
And then a cabal update && cabal install vector should grab the latest version from hackage.
I had a similar problem with another module after I installed the Haskell Platform over an existing (homebrewed) ghc install [Mac OS Mavericks 10.9.+]. I uninstalled the previous ghc with homebrew
brew uninstall ghc
and re-ran the Haskell Platform installer (.pkg on Mac). I then had to
sudo ghc-pkg recache
to resolve the out-of-date warning upon
ghc-pkg list
This resolved the problem in my case.
You might want to add the package to your .cabal file
I'm trying to install the nano-hmac-0.2.0 package (a dependency of a package I want) from Hackage using Cabal and GHC 6.12.1, but it fails with the following error:
Data/Digest/OpenSSL/HMAC.hsc:1:0:
Warning: Module `Prelude' is deprecated:
You are using the old package `base' version 3.x.
Future GHC versions will not support base version 3.x. You
should update your code to use the new base version 4.x.
<no location info>:
Failing due to -Werror.
Sure enough, the package's .cabal file has the following line in it:
ghc-options: -Wall -Werror -O2 -fvia-C
I'd like to be able to override the -Werror option so I can install the package without manually modifying the .cabal file, but can't find a way that will work. In particular, I tried passing --ghc-options to Cabal to stick a -Wwarn in GHC's argument list, like this:
$ cabal install nano-hmac-0.2.0 -v2 --ghc-options='-Wwarn'
This doesn't do what I want, though; the verbose output verifies that -Wwarn is getting added to the beginning of GHC's argument list, but the -Werror from the .cabal file appears later and seems to override it:
/usr/bin/ghc -Wwarn --make -package-name nano-hmac-0.2.0 -hide-all-packages -fbuilding-cabal-package -i -idist/build -i. -idist/build/autogen -Idist/build/autogen -Idist/build -optP-include -optPdist/build/autogen/cabal_macros.h -odir dist/build -hidir dist/build -stubdir dist/build -package-id base-3.0.3.2-0092f5a086872e0cdaf979254933cd43 -package-id bytestring-0.9.1.5-125aff5b9d19ec30231ae2684b8c8577 -O -Wall -Werror -O2 -fvia-C -XForeignFunctionInterface -XBangPatterns -XCPP Data.Digest.OpenSSL.HMAC
I also tried passing --constraint='base >= 4' to Cabal to force it to use a more recent version of base and avoid the warning entirely, but I get the same failure, and I still see the following in the verbose output:
Dependency base ==3.0.3.2: using base-3.0.3.2
Is there a way to get rid of or override the -Werror coming from the .cabal file via the Cabal command line, or am I stuck modifying the .cabal file myself?
Is there a way to get rid of or override the -Werror coming from the .cabal file via the Cabal command line, or am I stuck modifying the .cabal file myself?
Indeed. There's no way in general. You may be able to override package constraints such that the warnings go away, however, in general, you must modify the .cabal file.
These days Hackage prevents people uploading packages with -Werror in their .cabal file, so the issue will go away over time.
