此问题仅yak-shaving尝试对another problem进行问题排查。

因此,为了诊断我的另一个问题,我被建议尝试:

cabal unpack base
cd base-4.3.1.0
cabal haddock

看看它做了什么。

仅当我cabal unpack base时,它解压缩base-3.0.3.2。然后cabal haddock抱怨我需要首先运行cabal configure然后失败(遗憾地丢失了确切的错误)。

所以我决定安装base-4.3.1.0,这样我就可以完全重复说明了 即使安装完成后,cabal unpack base也会解包base-3.0.3.2,但cabal unpack base-4.3.1.0会解压缩base-4.3.1.0

现在我无法配置:

% cabal unpack base
Unpacking to base-3.0.3.2/
% cd base-3.0.3.2
% cabal haddock
cabal: Run the 'configure' command first.
% cabal configure

cabal: At least the following dependencies are missing:
base >=4.0 && <4.3, syb ==0.1.*
% cd ..

% cabal unpack base-4.3.1.0
Unpacking to base-4.3.1.0/
% cd base-4.3.1.0
% cabal haddock
cabal: Run the 'configure' command first.
% cabal configure

% cd ..

另外,我无法恢复到base-3.0.3.2,因为它取决于拥有 基本版&gt; = 4.0&lt; 4.3(WTF?),我无法安装base-4.2.0.2 b / c它失败了 b / c它找不到base.buildinfo.in

                   It depends on a later version of base, and was probably
                   supplied with your compiler when it was installed.

我做错了什么,如何解决?

答案 0 :(得分:5)

没有人打算自编base。它与特定的ghc安装相关联,因此如果构建它,则无法使用任何其他基本包。基础包不是用hackage构建的,我并不感到惊讶;很可能没有人试图建立它。

无论如何,我会尝试checking out the ghc sourcebase.buildinfo.in文件将位于base package repo中。您可以将文件从repo复制到解压缩的发行版,但是从签出的源代码构建可能更好。

确保只安装文档而不是库。
