我试图建立一个耶索德项目如下:耶索德与stackage未能安装由于依赖问题
mkdir sample_blog
curl -o cabal.config www.stackage.org/nightly/cabal.config
cabal install alex happy yesod-bin
但是,我得到了以下错误:
Resolving dependencies...
cabal: Could not resolve dependencies:
next goal: Cabal (user goal)
rejecting: Cabal-1.18.1.4/installed-d6c... (global constraint requires
==1.18.1.3)

Dependency tree exhaustively searched.
Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.
我已经使用自制软件安装GHC和cabal-install。 版本:
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.8.3
$ cabal --version
cabal-install version 1.20.0.4
using version 1.20.0.3 of the Cabal library
要确认,你想要一个针对仓库的问题,而不是自制。 – 11Kilobytes
是的,这个问题很好,谢谢。如果有人从自制软件中解释为什么他们有不同的版本,这将是很好的。现在我想到了,理论上* *所有Mac用户都有不同版本的Cabal库。 –
顺便说一下,当我将yesod-bin安装到我的沙盒中时,我现在该做什么。如果我使用./cabal-sandbox/bin/yesod init创建一个新项目,我会得到一个没有cabal-sandbox的新子目录。那么,我该如何在当前目录中创建一个新项目? – 11Kilobytes
