无法安装cabal包

Question

我在ubuntu 14.4 LTS上安装cabal的quickcheck时遇到了问题。我已经更新了cabal，但当我尝试安装quickcheck时，出现了一个错误：

:~$ cabal install quickcheck
Resolving dependencies...
Configuring primitive-0.6.1.0...
Building primitive-0.6.1.0...
Preprocessing library primitive-0.6.1.0...
ghc: ghc no longer supports single-file style package databases (dist/package.conf.inplace) use 'ghc-pkg init' to create the database with the correct format.
Failed to install primitive-0.6.1.0

Failed to install random-1.1
cabal: Error: some packages failed to install:
QuickCheck-2.8.1 depends on random-1.1 which failed to install.
primitive-0.6.1.0 failed during the building phase. The exception was:
ExitFailure 1
random-1.1 failed during the building phase. The exception was:
ExitFailure 1
tf-random-0.5 depends on random-1.1 which failed to install.

我是一个非常新的ubuntu，所以我仍然不知道在这种情况下该怎么做。我真的希望有人能帮上忙，因为这是为了一个即将完成的学校项目。

Answer 1

在花了几个小时安装/删除后，安装和配置最新的cabal，ghc的最好方法...

curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh

Answer 2

当你有一个与你的ghc版本相比非常旧的cabal二进制文件时，就会发生这个错误。

您可以跳过包管理器路径，也可以使用从https://www.haskell.org/cabal/download.html下载的linux二进制文件

这应该足以让你离开地面。
