在阴谋沙箱中使用Fay [英] Using Fay in a cabal sandbox

问题描述

我刚刚开始使用阴谋沙箱和Fay.但是，Fay似乎无法自动找到这些软件包，大概是因为它们不在全局" cabal软件包数据库中.我尝试遵循此Wiki页面上的建议，但未成功在我看来:

I've just started using both cabal sandboxes and Fay. However, Fay seems unable to find the packages automatically, presumably as they are not in the 'global' cabal package database. I tried unsuccessfully to follow the advice on this wiki page, which to me looked like:

./cabal-sandbox/bin/fay.exe --base-path .cabal-sandbox/i386-windows-ghc-7.6.3/fay-base-0.19/src/ Frontend.hs

但是Fay仍然抱怨它cannot find package fay-base.有什么我可以做的，还是我必须在沙箱外部安装Fay?

But Fay still complains it cannot find package fay-base. Is there something I can do about this, or must I install Fay outside the sandbox?

推荐答案

您不需要提供基本路径，但是需要通过传递--package-conf或设置HASKELL_PACKAGE_SANDBOX将其指向正确的程序包配置.环境变量.

You don't need to supply the base path, but you need to point it to the correct package config by passing --package-conf or setting the HASKELL_PACKAGE_SANDBOX environment variable.

例如:

./.cabal-sandbox/bin/fay --package-conf=.cabal-sandbox/x86_64-osx-ghc-7.6.3-packages.conf.d examples/alert.hs

或

HASKELL_PACKAGE_SANDBOX=./.cabal-sandbox/x86_64-osx-ghc-7.6.3-packages.conf.d ./.cabal-sandbox/bin/fay examples/alert.hs
