Question

我在archlinux上的$HOME安装了ghc-7.2.2未知的linux tar.bz2。

成功安装了多个软件包，并尝试安装cabal-dev。 parsec-numbers，text，ad等我得到：

cabal: cannot configure base-4.4.1.0 It requires ghc-prim -any
integer-simple and rts -any
There is no available version (of each of the above for example)

这在我的安装或可能的错误中是一个明显的错误吗？

我有适当的$GHC_PACKAGES_PATH设置并运行了ghc-pkg recache。

这是我安装的软件包列表：

是的，bytestring-0.9.0.2应该是-0.9.2.0，道歉。

哈哈。尝试使用＆amp; 2＆gt;文件捕获输出错过了“cabal：无法配置bytestring-0.9.2.0。它需要ghc-prim -any ...（与之前相同）”

Answer 1

那条消息，

cabal：无法配置base-4.4.1.0

意味着cabal正在尝试重新安装base，或者更幸运的是，它并没有尝试实际执行此操作（这是不可能的，基础与编译器紧密交织，你绝对肯定不能重新安装它）。但是你正在尝试安装需要重新安装基础的东西。

问题是您尝试安装的一个（或多个）软件包取决于integer-simple。 base取决于integer-gmp或integer-simple。这两个包都提供了Integer类型的实现以及涉及它的一些基本操作，因此您只能拥有这两个中的一个。默认值为integer-gmp，因为它是具有更高性能的那个，并且是您已安装的那个（并且所有[？]预构建的二进制文件都是使用它构建的。）

如果你确实需要一个取决于integer-simple的软件包，你必须自己从源代码构建GHC（我建议在构建之后保留一个integer-gmp，你必须保留它们但是，如果它们是相同的GHC版本，例如正常的〜/ bin（和〜/ lib），另一个位于〜/ simple / $ dir中。

从源代码构建它并不是很困难，但确实需要一段时间。程序是

下载源代码tarball并将其解压缩
在编辑器中打开mk / config.mk.in，将INTEGER_LIBRARY更改为integer-simple并保存
$ cd ghc-7.2.2
$ ./configure --prefix = $ HOME / whereever / you / want / it
$ make＆amp;＆amp; make install

GHC 7.2.2没有可用的ghc-prim -any版本
