Cabal：安装和更新软件包时出现问题

Question

我试图使用cabal安装threadscope软件包，但收到关于cabal太过时的错误：

cabal: Error: some packages failed to install:
cairo-0.13.8.0 failed during the configure step. The exception was:
user error (The package 'cairo' requires Cabal library version -any && >=1.24
but no suitable version is installed.)
gio-0.13.8.0 depends on glib-0.13.8.0 which failed to install.
glib-0.13.8.0 failed during the configure step. The exception was:
user error (The package 'glib' requires Cabal library version -any && >=1.24
but no suitable version is installed.)
gtk-0.14.7 depends on glib-0.13.8.0 which failed to install.
pango-0.13.8.0 depends on glib-0.13.8.0 which failed to install.
threadscope-0.2.11.1 depends on glib-0.13.8.0 which failed to install.

但是当我尝试用cabal install cabal-install时我得到：

Resolving dependencies...
Configuring Cabal-3.0.0.0...
Failed to install Cabal-3.0.0.0
Build log ( /home/ignacio/.cabal/logs/Cabal-3.0.0.0.log ):

#if !(MIN_VERSION_base(4,13,0))

)
cabal-install-3.0.0.0 depends on Cabal-3.0.0.0 which failed to install.
hackage-security-0.5.3.0 depends on Cabal-3.0.0.0 which failed to install.

我正在使用Ubuntu 16.04

cabal安装版本1.22.6.0使用Cabal库的1.22.5.0版

如果您能提供任何帮助，我将非常感谢。（对不起，如果我写了一些奇怪的东西，英语不是我的母语，并且我是ubuntu的新手）

Answer 1

问题是我使用的是ghc的过时版本，重新安装了所有内容以进行更新，现在它可以工作了。

Answer 2

您看到的错误...

error: missing binary operator before token "("
#if !(MIN_VERSION_base(4,13,0))
^
)

...提到MIN_VERSION_ CPP宏之一]（https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/phases.html#standard-cpp-macros），仅适用于GHC 8及更高版本。大概您的系统中有旧版本，这就是为什么更新可以解决问题的原因。有关其他地方的类似报告，请参见cabal issue #4092。
