Haskell在启用分析后重新安装基础 [英] Haskell reinstall base with profiling enabled
问题描述
我尝试按照此处中列出的说明重新安装我的Haskell库并启用了分析功能。
但是,每当cabal尝试重新安装其中一个库时,我会收到以下消息:
LibraryNameHere .hs:1:1:
找不到模块`Prelude'
也许你还没有安装包`base'的分析库?
使用-v查看搜索的文件列表。
当我试图用分析重新安装 base
时启用我得到以下消息:
$ $ p $ $ $ c $ me @ machine:〜/ .cabal / $ cabal install -p base
解决依赖关系...
所有请求的软件包已经安装:
base-4.5.0.0
如果您想要重新安装,请使用--reinstall。
me @ machine:〜/ .cabal / $ cabal install --reinstall -p base
解析依赖关系...
cabal:无法解析依赖关系:
next goal:base (用户目标)
拒绝:base-4.7.0.0,4.6.0.1,4.6.0.0,4.5.1.0,4.5.0.0,4.4.1.0,4.0.0.0,
4.3.1.0,4.3。 0.0,4.2.0.2,4.2.0.1,4.2.0.0,4.1.0.0,4.0.0.0(只能使用已安装的
实例)
rejecting:base-3.0.3.2(conflict:base = >< 4.3> base> = 4.0&< 4.3)
rejecting:base-3.0.3.1(conflict:base => base> = 4.0&& code>
如何重新启用基本分析功能?

I am trying reinstall my Haskell libraries with profiling enabled by following the instructions listed here
However, whenever cabal attempts to reinstall one of the libraries I get the following message:
LibraryNameHere.hs:1:1:
Could not find module `Prelude'
Perhaps you haven't installed the profiling libraries for package `base'?
Use -v to see a list of the files searched for.
When I try to reinstall base
with profiling enabled I get the following messages:
me@machine:~/.cabal/$ cabal install -p base
Resolving dependencies...
All the requested packages are already installed:
base-4.5.0.0
Use --reinstall if you want to reinstall anyway.
me@machine:~/.cabal/$ cabal install --reinstall -p base
Resolving dependencies...
cabal: Could not resolve dependencies:
next goal: base (user goal)
rejecting: base-4.7.0.0, 4.6.0.1, 4.6.0.0, 4.5.1.0, 4.5.0.0, 4.4.1.0, 4.4.0.0,
4.3.1.0, 4.3.0.0, 4.2.0.2, 4.2.0.1, 4.2.0.0, 4.1.0.0, 4.0.0.0 (only already
installed instances can be used)
rejecting: base-3.0.3.2 (conflict: base => base>=4.0 && <4.3)
rejecting: base-3.0.3.1 (conflict: base => base>=4.0 && <4.2)
How do I reinstall base with profiling enabled?
If the base
profiling libraries were not included in the your Haskell/GHC installation by default, they will be included through your OS's package manager in a separate package.
