haskell - 安装反应香蕉 wx

Question

当您尝试安装库 reactie-banana-wx 时，出现错误：

src\CRUD.hs:10:18: Could not find module `Data.Map': It is a member of the hidden package `containers-0.4.0.0'. Perhaps you need to add `containers' to the build-depends in your .cabal file.

安装命令：

cabal install reactive-banana-wx

请帮助纠正问题。

Answer 1

它提供的建议是合理的，如果有点令人困惑：cabal install隐藏它生成.cabal文件的步骤！以下是您可以明确地执行该部分的方法：

cabal unpack reactive-banana-wx
cd reactive-banana-wx-*
gvim *.cabal # or whatever editor you prefer
# follow the instructions given in the error
cabal install
