为elm服务器编译aeson漂亮时出错

Question

我试图在一个elm-server linux盒上安装x86_64，它由于aeson-pretty编译的错误而失败。我将感谢帮助修复此错误。在谷歌上搜索错误并没有多大帮助。所以，我要伸出手来。

对于我所要做的工作，首先要运行的是阴谋式的模拟输出--它显示了哪些依赖项将改变：

$ cabal install elm-server --max-backjumps 1000 -v --dry-run
Reading available packages...
Choosing modular solver.
Resolving dependencies...
In order, the following would be installed:
aeson-0.7.0.2 (reinstall)
aeson-pretty-0.7.1 (reinstall) changes: aeson-0.7.0.1 -> 0.7.0.2,
attoparsec-0.10.4.0 added, cmdargs-0.10.3 added
pandoc-types-1.12.3.2 (reinstall)
texmath-0.6.6 (reinstall)
yaml-0.8.8.1 (reinstall)
pandoc-1.12.3.3 (reinstall) changes: old-time-1.1.0.1 added
Elm-0.12 (reinstall) changes: aeson-0.7.0.1 -> 0.7.0.2, aeson-pretty-0.7.1
added, pandoc-1.12.3.3 added
elm-server-0.11 (new package)

在实际运行期间编译aeson-pretty时出错--我将欣赏有关如何解决此问题的指针(我已经从下面的日志中删除了绝对文件系统路径，以删除工作服务器的一些标识信息)：

在template-haskell上运行template-haskell，我知道以下内容：

$ ghc-pkg list template-haskell
WARNING: there are broken packages.  Run 'ghc-pkg check' for more details.
ghc/7.6.1/lib/ghc-7.6.1/package.conf.d
   template-haskell-2.8.0.0
.ghc/x86_64-linux-7.6.1/package.conf.d
   template-haskell-2.8.0.0

运行ghc-pkg检查，我得到了以下内容(只是为了验证不是template-haskell坏了)-因为需要用elm-server重新安装Elm，所以这是合理的。

The following packages are broken, either because they have a problem
listed above, or because they depend on a broken package.
Elm-0.12

因此，看来我需要自己对elm-server的阴谋包进行修改，以修复对template-haskell的一些依赖。要做到这一点，我需要了解如何从阴谋配置的角度调试上述错误。

如果有人想知道沙箱，我不想使用cabal sandbox，因为工作服务器上的磁盘配额限制。如果我能让elm和elm-server安装，我就不介意破坏现有的软件包。

模板-haskell是绑定到您的GHC版本，所以它不应该在您的用户包数据库。取消注册模板-haskell然后重新安装任何破碎的软件包。
