I'm using stack lts-9.0 snapshot, which includes process-1.4.X. Due to some problems with this version, I would like to use process-1.6.1.0. Adding this version to extra-deps does not seem to be enough:
extra-deps:
- process-1.6.1.0
since this will cause the following error:
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for Cabal-1.24.2.0:
process-1.6.1.0 must match >=1.1.0.1 && <1.5 (latest applicable is 1.4.3.0)
What do I need to do in these cases?
As written in the message, the problem is with Cabal-1.24.2.0 depending on process < 1.5.
Add Cabal-2.0.0.2 to the extra-deps.

I'm trying to set up a happstack-lite application using stack.
I initialized project with these commands:
stack new my-happstack
cd my-happstack
stack setup
I changed package.yaml so it contains:
dependencies:
- base >= 4.7 && < 5
- happstack-lite >= 7.3
Then I ran stack build several times and changed extra-deps in stack.yaml in project directory according to recommendations (added dependencies, such as happstack-server).
Apparently, I was asked to add to extra-deps the packages already listed there, with different version bounds and one with the same (template-haskell-2.11.1.0):
stack.yaml content:
extra-deps:
- happstack-lite-7.3.6

Some different approaches to resolving this:
* Set 'allow-newer: true' in C:\sr\config.yaml to ignore all version constraints and build anyway.
* 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

I've tried these steps:
1) Set 'allow-newer: true' in C:\sr\config.yaml. In this case, I'm getting error about wrong types usage from inside one of the dependent packages (can paste error output upon request, if needed).
2) Run stack solver. I've got the error from cabal planner (error output upon request).
So, I expect stack to resolve dependencies the way npm does - each package dependencies are resolved independently from other's packages needs. Any advice of how I can solve this particular problem will be helpful, though (including manual dependencies resolving).
I want to install the Haskell libary hip from https://hackage.haskell.org/package/hip by using stack. This does not work, because stack seems to not being able to install dependencies.
I have stack freshly installed by curl -sSL https://get.haskellstack.org/ | sh, and stack --version gives me

I have tried several things like another resolver, reinstalling different versions of stack, ghc or cabal.
I have tried stack new test, and inside the test folder, i wrote stack install hip.
I got the following error:
Error: While constructing the build plan, the following exceptions were

needed since hip is a build target.

attempt to find some working build configuration. This can be convenient

I expect something like:

Please tell me if i did not provide all infos necessary for you to help me with my problem.
Installing with the resolver lts-7.5 works.
Why not do what stack recommended?
Recommended action: try adding the following to your extra-deps

Chart-1.9#sha256:f41568b6b3704f66c2ec163295b430ab7d798f91de426c2d5aba747d1135cd9b

It's the easiest way to accomplish your goal.
Update: lts-10.10 is the most recent resolver to include hip. If you update your stack.yaml to use lts-10.10 and add hip in your .cabal file, you should be good to go.
All I want is to parse a simple string using regex.
First question: Should I be using Text.Regex or something else? Stackage lists at least 11 regex packages. I don't care if it's PCRE or Posix. At this point I'll accept anything.
Second Question: How do I include Text.Regex in my project? This is my experience so far:
package.yaml has
dependencies:
- base >= 4.7 && < 5
- regex

???
It says I need to add a line I already added.
Do I need a different version of regex? If so, which one, and how do I figure that out?
There are a few recommendations in the comments as to what to use: regex-base, but it is also good to understand why it is not compiling.
Stackage provides a list of compatible packages in each LTS. You can alter some of the version numbers as long as they respect the version constraints of other dependencies. Not all of these dependency restrictions are well defined in the packages coming from Hackage, which is one of the reasons for using Stackage.
Generally each stackage major LTS release is associated with a particular version of GHC which also has a particular version of base. When you pick a major version of LTS, you are also picking a version of GHC and base. If you want to change GHC and/or base versions, it is easier to change the LTS version. The first thing after the LTS version on the Stackage LTS page is the GHC version number.
In your case regex requires a version of template-haskell and base-compat that violate the constraints of other dependencies.
I'm trying to include a specific version of a library in a Haskell project. The library is bed-and-breakfast (which is used for martix operations), but I need the specific version 0.4.3 which fixed a bug with the multiplication implementation.
So, my stack.yaml looks like this:
flags: {}
extra-package-dbs: []
packages:
- .
extra-deps:
- bed-and-breakfast-0.4
- base-4.6.0.1
resolver: lts-12.8
But I'm getting this error when building:
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for bed-and-breakfast-0.4:
base-4.11.1.0 from stack configuration does not match >=4.5 && <4.7 (latest matching version

needed due to realworldhaskell-0.1.0.0 -> bed-and-breakfast-0.4
Some different approaches to resolving this:
* Set 'allow-newer: true' to ignore all version constraints and build anyway.
* 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 C:\Users\info\Desktop\Projects\haskell\stack.yaml:
- base-4.6.0.1
I've done the recommended action but it didn't solve anything. I've tried using different resolvers to see if it's an issue with my GHCi version but nothings worked. What is the best way to interpret error messages like this and how should I proceed?
EDIT:
If I remove -base.4.6.0.1 and add allow-newer: true I get this:

Cabal-simple_Z6RU0evB_2.2.0.1_ghc-8.4.3.exe: The package has an impossible
version range for a dependency on an internal library: bed-and-breakfast
==0.3.2. This version range does not include the current package, and must be
removed as the current package's library will always be used.
EDIT 2:
Ok, so I'm guessing that the bed-and-breakfast library needs base 4.11.1.0 which is included in GHCi 6.10.2 (according to https://wiki.haskell.org/Base_package) so I need a resolver which matches that GHCi version. Where can I find out what resolver version that is?
Here is the constraint on the latest available bed-and-breakfast package: base (>=4.5 && <4.7), which means it will likely not even compile with GHC version higher then 7.6. Considering that there is even no LTS snapshot prior to GHC 7.8, you are out of luck with that package.
To say it in another words, the package is outdated and your choices are:
submit an issue and hope maintainer will do something about it
try to make it work with newer ghc yourself
Use a different package
I'm trying to set up Hakyll on a fresh Ubuntu 16.04 instance, but I can't seem to get the Stack-based setup instructions right.
Starting out with stack install hakyll, I get:
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for hakyll-4.9.3.0:
http-conduit-2.1.11 must match >=2.2 && <2.3 (latest applicable is 2.2.3)
Plan construction failed.
I got a similar error when tying to stack-install http-conduit-2.1.11, this time with:
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for http-conduit-2.2.3:
http-client-0.4.31.2 must match >=0.5 && <0.6 (latest applicable is 0.5.5)
http-client-tls-0.2.4.1 must match >=0.3 && <0.4 (latest applicable is 0.3.3.1)
Plan construction failed.
After resolving dependencies for this (also using Stack), I tried once again to stack install http-conduit-2.1.11, but I once again got the same dependency error.
The packages http-client-0.4.31.2 and http-client-tls-0.2.4.1 appear in my ~/.stack/precompiled/x86_64-linux/ghc-8.0.1/1.24.0.0/, which isn't explicitly in my $PATH, however that feels like an extremely hacky solution, and I haven't found any documentation recommending this approach.
How can I correctly install Hakyll on my machine?
Dependency management with stack is meant to be reproducible and declarative, that means that a stack project will only compile once all dependencies are recorded in the .cabal file(s) of the project and once the stack.yaml of the project defines versions for these dependencies either in the resolver or the extra-deps section.
Your confusion seems to stem from a misunderstanding of what stack install does. The command line help has this to say about it:
build Build the package(s) in this directory/configuration
install Shortcut for 'build --copy-bins'
...
--[no-]copy-bins Enable/disable copying binaries to the local-bin-path
(see 'stack path')
stack install does not save any dependencies.
So the proper way of making hakyll available as a dependency to your code is:
Create a proper stack project with stack init if you already have a Cabal package, or stack new if you don't.
Add hakyll to the library or executable build-depends in your .cabal file.
Attempt to stack build and follow the instructions in any error messages until all issues are resolved.
A simpler solution than #sjakobi's in this case was to specify a resolver as a command line option when starting a new Stack project:
stack install hakyll --resolver=5.11 --install-ghc
