I have a package installed via cabal: Data.Vector
But when I attempt to compile a program that has import Data.Vector in it:
Drews-MacBook-Pro:Blokus-AI drewgross$ ghc --make -O2 -prof -auto-all playGame
Grid.hs:28:8:
Could not find module `Data.Vector'
Perhaps you meant
Data.Tensor (from Tensor-1.0.0.1)
Data.Functor (from base)
Use -v to see a list of the files searched for.
Drews-MacBook-Pro:Blokus-AI drewgross$
The command I used to install was:
cabal install -p --reinstall --force-reinstalls vector
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

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:

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'd like to remove terminfo package from the default dependencies of my GHC installation, as the generated executable does not run in a particular environment without libtinfo, saying:
./Main: error while loading shared libraries: libtinfo.so.6: cannot
open shared object file: No such file or directory
So, is there any neat way to remove dependency on terminfo package?
The only way I found is to use -hide-all-packages of ghc and then enumerate all required default packages via -package option:
ghc -hide-all-packages -package-db ~/.cabal/store/ghc-8.10.7/package.db \
-package base -package containers -package array -package template-haskell \
-package unix -package filepath -package process -package directory \
-package time --make Main.hs
Options like -hide-package or -ignore-package doesn't work.
$ ghc -ignore-package terminfo -ignore-package ghc --make Main.hs
Loaded package environment from /home/keigoi/.ghc/x86_64-linux-8.10.7/environments/default
<command line>: cannot satisfy -package-id ghc-8.10.7:
ghc-8.10.7 is ignored due to an -ignore-package flag
(use -v for more information)
Any ideas?
Some thoughts and additional findings:
(*) I have no idea why the generated binary depends on it -- the package is required by GHC API, which is not always necessary I think and I didn't use it.
Actually, binaries generated from the fresh installation (as of GHC 8.10 or 9.2 from ghcup) does not depend on libtinfo.
Under the circumstance that ~/.ghc/x86_64-linux-8.10.7/environments/default does not exist, the generated binary has no dependency to libtinfo. This file is generated when you initialize Cabal. After that, the compiled binary will depend on libtinfo.so.
(**) Commands like strip seems not to elimite that dependency.
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

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!

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)?

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 am very new to the Haskell platform and I'm having much more trouble than I had wished for with it.
I think I'm getting closer since everything goes well until cabal tries to install shakespeare-css and derive.
I'm working on a Ubuntu 11.10 with ghc-7.4.2 and cabal-install 1.16.0.2
When I input command
~/.cabal/bin$ ./cabal -v install derive
I get the following output

What is the problem here?
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?

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.
