安装reactive-banana-wx

Question

当您尝试安装库reactie-banana-wx时，会收到以下错误：

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.

已安装命令：

cabal install reactive-banana-wx

请帮助更正此问题。

Answer 1

它提供的建议是合理的，尽管有点令人困惑：cabal install隐藏了生成.cabal文件的步骤！下面是你如何显式地完成这一部分：

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
