Cabal:cabal配置失败

Question

这个问题只是傻瓜试图解决另一个问题.

所以,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.

只有,当我这样做时cabal unpack base,它打开包装base-3.0.3.2.然后cabal haddock抱怨我需要先运行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也要打开包装base-3.0.3.2,但要cabal unpack base-4.3.1.0打开包装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,因为它依赖于基本版本> = 4.0 <4.3(WTF？),而我无法安装base-4.2.0.2 b/c它失败了b/c它找不到base.buildinfo.in.

    Description:   This is a backwards-compatible version of the base package.
                   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,我该如何解决？

Answer 1

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,我试着查看ghc源代码.该base.buildinfo.in文件将位于基本包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.
