I'm trying to install hlint through stack in haskell stack install hlint, but it advised me that the plan failed and I should add some extra-deps in stack.yaml.

After i did that (and set allow-newer: true in config.yaml) , it returned to me the following:

    The same package name is used in multiple local packages

time used in:
- PLImmutable (PLIHackage (PackageIdentifier {pkgName = PackageName "time", pkgVersion = mkVersion [1,10]}) 536801b30aa2ce66da07cb19847827662650907efb2af4c8bef0a6276445075f,5738 (TreeKey 1591d9d1034f19cd38fbda525969f805b5ca083b45da85602cf2b04c1a82f640,6693))
- PLImmutable (PLIHackage (PackageIdentifier {pkgName = PackageName "time", pkgVersion = mkVersion [1,11,1,2]}) a957467595420495c2dd440d9efa1f58c62277cf9438c7e7a515d7a4c65571ec,6287 (TreeKey b7025dd19573d4c082d072eaba093a3fc1f891f3fde09b59561bcdca3566a0a4,7048))

I don't know how to make it right, since the cmd didn't gave me any new instructions. Help?

Installing things with the global stack.yaml/config.yaml can be tricky. It's often better to clone the package repo and build it using its own config files, which specify the package's preferred Stack resolver etc. Try this:

git clone git@github.com:ndmitchell/hlint.git
# Or: git clone https://github.com/ndmitchell/hlint.git

cd hlint
git checkout v3.3.1 # Latest available release
stack install
