我正在尝试安装光泽，但我不知道为什么 ghci 找不到模块。
当我做 cabal 安装光泽时，它说：
Up to date
Warning: You asked to install executables, but there are no executables in
target: gloss. Perhaps you want to use --lib to install libraries instead.
当我做 cabal install -lib gloss 它给了我这个错误：

Try running with --minimize-conflict-set to improve the error message.
这很奇怪，因为我第一次使用此命令时它运行良好，但是当我尝试在 ghci ´´´import ...´´´ 上执行时，它说：找不到模块。
我尝试了其他模块，它给了我同样的错误。我认为问题可能是 ghc 无法在保存包的 cabal 文件夹中搜索，但我不再确定。
我怎样才能解决这个问题？谢谢
