haskell - Error installing Data.Aeson

Question

Hello can anyone tell me how can i install the Data.Aeson package?I am running into the following error:

WARNING: cache is out WoAfR NdaItNeG::  Cc:a/cUhsee riss/ aodurti aonf.b edrcaotev:i ciC/:Ap/pUDsaeta/rLso/caadlr/iParno.gbrearmcso/vsitcaic/kA/pxp8D6a_t6a4/-Lwoicnadlo/ws/Pgrhocg-r8a.ms0./2s\ltiabc\kp/xack8a6g_e6.4c-ownfi.ndd\poawcsk/agghec.-c8a.c0h.e2

Below it says Use ghc-pkg recache.When i try running this command i get the following error:

ghc-pkg.exe: C:\Program Files\Haskell Platform\8.4.2\lib\package.conf.d\package.cache: you don't have permission to modify this file

I have tried installing Data.Aeson both with cabal install Data.Aeson and with Stack install Data.Aeson.With the latter i get the following error:

Data.Aeson不是一个包，它是包中的许多模块之一，称为aeson. 试试cabal install aeson。
