我的规格是:

$ which ghc

$ cabal --version
cabal-install version 0.8.0

HaskellCharts安装指南(截至2010年5月27日)告诉我
cabal update
cabal install gtk2hs-buildtools
cabal install gtk
cabal install chart
cabal update 成功并告诉我,有一个更新版本的cabal可用.
$ cabal install gtk2hs-buildtools
然而,收益率

但是,在我的iWeb专用服务器上,这不起作用.大多数步骤都很好,直到它达到'./cabal install cabal-install',它会抛出以下错误:

我验证了包名称和版本,这没关系.
运行cabal install --dependencies-only说"已经安装了所有请求的包".
发生了什么以及如何解决？
如果相关我在Windows 7上使用QuickCheck-2.7.5使用cabal-install 1.20.0.3使用cabal 1.20.0.1和ghc 7.6.3.
通过runhaskell Setup configure输出配置:
配置MyPackage-0.1.0.0 ...
Setup.hs:至少缺少以下依赖项:QuickCheck == 2.7.5
在这个问题中,我们安装了依赖项Hat.现在,当我尝试做
cabal install Hat

如果在本地签出了一个库,该库使用应用程序使用的cabal构建.我想建立我的应用程序对抗本地库而不是hackage的东西,但我不知道如何做到这一点.这似乎是我应该做的事情,我似乎无法弄清楚如何.

所以我试着stack install wx,它提示我安装wxcore,这提示我安装wxc和wxdirect.在我之后stack install wxdirect,我尝试跑步stack install wxc,但是看见:
While constructing the BuildPlan the following exceptions were encountered:
-- Failure when adding dependencies:
wxdirect: needed (>=0.90.1.1), not present in build plan (latest is 0.92.1.0)

Could not find package wxdirect in known packages
Recommended action: try adding the following to your extra-deps in {project root}/stack.yaml
- wxdirect-0.92.1.0

当我尝试运行堆栈时,例如即使只是stack --version,我得到了

我该怎么做才能解决这个问题.这是在Homebrew最近的一些更新之后开始出现的.
