How do I check what version of a package is installed with stack?

Question

Within my project's .cabal file I've got the following under the executable section:

executable ArchPkgstatsScraper   hs-source-dirs:      app   main-is:             Main.hs   ghc-options:         -threaded -rtsopts -with-rtsopts=-N   build-depends:       base                        , ArchPkgStatsScraper                        , text                        , conduit                        , html-conduit                        , http-conduit                        , xml-conduit                        , resourcet                        , transformers 

After I've successfully installed / built the above with stack, how could I check which version of xml-conduit is installed?

Answer 1

The command

stack ls dependencies 

or for older version of stack:

stack list-dependencies 

will list every dependency installed for the current project, along with its version.
