安装 Data.Aeson 时出错

Question

你好谁能告诉我如何安装 Data.Aeson 包？我运行遇到以下错误：

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

下面说 Use ghc-pkg recache。当我尝试运行这个命令时，我得到以下错误：

ghc-pkg.exe: C:\Program Files\Haskell Platform.4.2\lib\package.conf.d\package.cache: you don't have permission to modify this file

我已经尝试使用 cabal install Data.Aeson 和 Stack install Data.Aeson 安装 Data.Aeson。对于后者，我得到以下错误：

Answer 1

Data.Aeson 不是包，它是名为 aeson 的包中的许多模块之一。试试 cabal install aeson.
