@Francesco: unfortunately nightly misses some package. So, I tried:
$ stack --resolver=ghc-8.2.2 setup --reinstall
Preparing to install GHC (tinfo6) to an isolated location. This will not
interfere with any system-level installation. Already downloaded.
Installed GHC.
stack will use a sandboxed GHC it installed
For more information on paths, see 'stack path' and 'stack exec env'
To use this GHC and packages outside of a project, consider using:
stack ghc, stack ghci, stack runghc, or stack exec
So seems that 8.2.2 was installed, right? But how to build the project
with new GHC now? I never used cabal before, `stack ghci` still runs
8.0.2 instead of 8.2.2. Installed GHC 8.2.2 does not correspond
to .yaml file LTS - maybe this is a reason why old 8.0.2 is stil used...
When I try cabal build/new-build/repl I get:
cabal: The program 'ghc' version >=6.4 is required but it could not be
found.
So, cabal does not know about installed GHC versions (at least 8.0.2,
used by stack). I tried --require-sandbox but without success.

You can see how to configure stack here:
https://github.com/commercialhaskell/stack/blob/release/doc/yaml_configuration.md
The short of it is that to have stack ghci choose a particular version of
ghc, you probably need to modify ~/.stack/global/stack.yaml, change
resolver to something here https://www.stackage.org/snapshots that has your
version of ghc and dependencies similar to what your project wants. For
example 'nightly-2017-12-10'.

Hey Paul,
four-step plan:
1. check where stack installed ghc, it should be something like:
~/.stack/programs/x86_32-linux/ghc-nopie-8.2.1/lib/ghc-8.2.1/bin
2. add these two lines to your `~/.bashrc`:
export PATH=~/.cabal/bin:$PATH # path to stuff built with cabal
export PATH=~/the.stackpathabove:$PATH # path to ghc
3. check the right ghc version has been selected:
ghc -v
# should be 8.2.2
4. cd into your project and `cabal new-build` and then open a repl on it
with `cabal new-repl`.
Let us know if this works!

1. GHC 8.2.2 is here:
~/.stack/programs/x86_64-linux/ghc-tinfo6-8.2.2/bin
2. done
3. yes, it's 8.2.2
4. `cabal new-build` said to me call `cabal update`, I done it, then run
it again and got:
$ cabal new-build
Resolving dependencies...
cabal: Could not resolve dependencies:
trying: XXX-0.5.0.0 (user goal)
next goal: YYY-utils (dependency of XXX-0.5.0.0)
Dependency tree exhaustively searched.

@David: I tried to switch to nightly but in project's .yaml file and
got error about missing of some library (as I understand, it is missing
in last nightly). So, if I try to do it through .yaml file then how to
use new GHC (8.2.2) but with LTS for 8.0.2? Is it possible? I need last
stable LTS where all libraries (using in the projects) exist, but with
new GHC 8.2.2 which is too new for stable LTS. As I read somewhere, GHC
version and Stackage version are linked together hardly in stack tool,
or?
