部署到 OpenShift 时 ReadArgs 上的 Cabal 构建失败

Question

我正在尝试将 Web 应用程序部署到 OpenShift。我的应用程序是用 Yesod web framework. I would like to use the Yesod cartridge from Haskell wiki.

编写的

我可以创建应用程序并部署随盒提供的示例。但是，当我向cabal文件中添加更多依赖项时，推送后的构建失败。

失败依赖的一个例子是ReadArgs。它因以下错误而失败：

remote: ReadArgs.hs:11:8:
remote:     Could not find module `Filesystem.Path'
remote:     There are files missing in the `system-filepath-0.4.12' package,
remote:     try running 'ghc-pkg check'.
remote:     Use -v to see a list of the files searched for.
remote:
remote: ReadArgs.hs:12:8:
remote:     Could not find module `Filesystem.Path.CurrentOS'
remote:     There are files missing in the `system-filepath-0.4.12' package,
remote:     try running 'ghc-pkg check'.
remote:     Use -v to see a list of the files searched for.

ghc-pkg check 命令表示以下关于 system-filepath:

There are problems in package system-filepath-0.4.12:

这些问题看起来很严重，但是它没有告诉我如何解决它。

如何找出构建失败的原因？我怎样才能构建它？

Answer 1

事实证明这是墨盒中的错误，现已修复。

它曾经是 issue #3，但问题跟踪器似乎已被删除。
