【问题描述】：
我在archlinux上的$HOME中安装了ghc-7.2.2 unknown linux tar.bz2。
在使用 cabal-dev 成功安装多个软件包后，尝试安装例如。我得到的 parsec-numbers、文本、广告等：
cabal: cannot configure base-4.4.1.0 It requires ghc-prim -any
integer-simple and rts -any
There is no available version (of each of the above for example)
这是我的安装中的明显错误还是可能的错误？
我设置了适当的$GHC_PACKAGES_PATH 并运行了 ghc-pkg recache。
这是我的已安装软件包列表：

哈哈。尝试使用 &2>file 捕获输出时遗漏了“cabal：无法配置 bytestring-0.9.2.0。它需要 ghc-prim -any...（与以前相同）”
【问题讨论】：
-
不要为此使用 cabal-dev，直接运行 cabal 以使其输出可捕获。但不要忘记 --dry-run。
-
哦，实际上比它不重新安装 bytestring 更有趣的是它认为应该重新安装的原因。出现这些错误时，您尝试安装哪个软件包？
$ cabal install -v3 --dry-run that-package会很好。 -
cabal install -v3 --dry-run bytestring => cabal：无法配置 bytestring-0.9.2.0。它需要 ghc-prim -any。没有可用的版本。 IPkg 广告依赖于整数简单 [
-
cabal-install -v3 --dry-run ad => "cabal: 无法配置 base-4.4.1.0。它需要 ghc-prim -any、integer-simple -any 和 rts -any。没有可用的版本..”
-
我尝试用 integer-simple 但是构建 ghc-7.2.2 src（使用我安装的 ghc-7.2.2 二进制文件）。 ./configure 覆盖 config.mk 编辑。我现在发现我也无法使用 integer-gmp 安装 ghc-7.2.2 src。
