I'm trying to install http-conduit-1.9.6, and running cabal install http-conduit-1.9.6 gives me the following error:
Network/HTTP/Conduit/Request.hs:43:8:

Perhaps you need to add `network' to the build-depends in your .cabal file.

I'm new with Haskell, and I'm now sure if having two repositories could be a problem. My work platform is Ubuntu 14.04, GHC 7.6.3, and cabal 1.20.

I have been unable to install any packages using Cabal, getting an error saying that the tar archive is not in the expected directory. For example, if I try to do, cabal install mtl, I get the following error:
Resolving dependencies...
Failed to install text-1.2.1.1
cabal: Error: some packages failed to install:
text-1.2.1.1 failed while unpacking the package. The exception was:
user error (File in tar archive is not in the expected directory. Expected:
"." but got the following hierarchy: ["text-1.2.1.1"])
I have run cabal update, and cabal --version gives the following:
$ cabal --version
cabal-install version 1.22.5.0
using version 1.22.4.0 of the Cabal library
Anyone have any ideas as to why this might be happening? Let me know if you need any additional information.
That version of cabal-install had a big making it almost completely unusable. Upgrading should solve this problem.

I am trying to install helm. When I try to install it, however I get this error:

Failed to install sdl2-1.1.0

I don't understand. According to Hackage, sdl2 is at version 1.1, but installing it requires version 2.0.3? I've tried this in and out of a sandbox. Results of ghc-pkg list are here if you think they're relevant: http://pastebin.com/tFrsfPFe
I'm on Ubuntu btw.
Help?
Another thing which could happen (happened to me) for other installs is that the PKG_CONFIG_PATH variable might not point to the package config file (sdl2.pc, for me in the /usr/local/lib/pkgconfig directory). pkg-config uses some default directories ('/usr/lib/pkgconfig' and '/usr/share/pkgconfig'), but if the sdl.pc file isn't in one of these, you'll have to specify the directory in the environment variable. You can check this with echo $PKG_CONFIG_PATH
If it turns out you need to set the variable, just use export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig (or to whatever directory your sdl2.pc file lives in)
I ran into the same problem, and I just want to add my solution here for the record. The native sdl2 libraries need to be installed first by following the directions here: https://github.com/haskell-game/sdl2#building
Deciding to learn Haskell, installed ghc on OS X via Homebrew (web binaries weren't downloading at the time).
All great, following along with Learn You a Haskell, but then decided to install some packages and see how things run.
cabal install clckwrks-cli was running fine until...
Public internet craps out half-way through install/build of a few projects.
Now, none of those programs will reinstall and in the case of clckwrks-cli, I get the following error:

Loving the language so far, NOT the package management :(
Cabal sandboxes are frequently recommended for development but work well for trying out some package quickly. If anything goes wrong they are easily disposable and don't affect any other packages you have already installed. Here is what I would do to try out clckwrks-cli (BTW, if you want to just try out any package you might to choose another package with less dependencies).
$ cd /path/to/sandboxes
$ cabal get clckwrks-cli
$ cd clckwrks-cli-<version>
$ cabal sandbox init
$ cabal install --only-dependencies -j<N> # N is the number of CPU cores
At this point you can type cabal run to run the executable installed by the package (which it'll probably be at ./dist/build/bin/), cabal test for running tests, or cabal repl in order to run a ghci session with the sandboxes packages available.
If anything goes wrong you can revert back the sandbox by typing cabal sandbox delete and cabal clean. When you are done you can safely remove the sandbox without affecting other packages.
Here is what worked for me in the past
For a package $f, do
ghc-pkg.exe unregister --global --force $f
ghc-pkg.exe recache
According to its documentation, ghc-pkg.exe unregister "unregisters a package" and recache "regenerate the package database cache". --global needs to be used if the package in question was installed in system directories.
In case the database is severely damaged, I would delete the user or system cabal directory and reinstall packages that I had. I usually do this by cabal install one or several of the application libraries that I use, and let cabal reinstall the dependencies. Note: the cabal directory depends on the OS and version of GHC.
ghc-pkg unregister --force clckwrks-cli
I was having trouble with unordered-containers-0.2.5.1 and deleting the file:
~/.cabal/packages/hackage.haskell.org/unordered-containers/0.2.5.1/unordered-containers-0.2.5.1.tar.gz
fixed the problem for me. (i.e. the error cabal: data is not in tar format)
I am having lots of problems with cabal-install:
1: Every time I do cabal update, it tells me to do cabal install cabal-install, so I do, and then when I do cabal update again, it says the same thing.
2: When I try to install ghc-mod from hackage, it gives me this error:
[username#arch ~]$ cabal install ghc-mod
In order, the following will be installed:
haskell-src-exts-1.14.0 (reinstall) changes: pretty-1.1.1.1 -> 1.1.1.0
hlint-1.8.55 (reinstall)
ghc-mod-3.1.4
setup: The program happy version >=1.17 is required but it could not be found.
ghc-mod-3.1.4 depends on haskell-src-exts-1.14.0 which failed to install.
haskell-src-exts-1.14.0 failed during the configure step.
hlint-1.8.55 depends on haskell-src-exts-1.14.0 which failed to install.
So the problem was The program happy version >=1.17 is required but it could not be found., so I installed happy 1.19.2 using cabal install happy without problems.
I tried cabal install ghc-mod again, same error, so I tried cabal install haskell-src-exts --reinstall --force-reinstalls. It gave me the following error:
[username#arch ~]$ cabal install haskell-src-exts --reinstall --force-reinstalls
Configuring haskell-src-exts-1.14.0...
setup: The program happy version >=1.17 is required but it could not be found.
Failed to install haskell-src-exts-1.14.0
cabal: Error: some packages failed to install:
haskell-src-exts-1.14.0 failed during the configure step. The exception was:
ExitFailure 1
Basically The program happy version >=1.17 is required but it could not be found.. So happy is the problem again?
I have also tried downloading the tar.gz files from hackage and using cabal install on the
.cabal file, also modified the .cabal file to ignore dependencies, still failed.
cabal install places executables in ~/.cabal/bin.
If you add it to your path, you will be able to use the new executables installed by cabal:
$ PATH=$HOME/.cabal/bin:$PATH
I encountered with same problem and I solved the problem with installing happy package(confusing package name). So install it with your package manager(apt-get, pacman etc) before install package with cabal. This should be fix the problem.
