Yesod on Heroku:无法解析依赖项，yesod-1.1.9.2

Question

我使用yesod init创建了一个新的应用程序，然后按照教程here将其部署到Heroku。

部署失败，出现以下错误：

-----> Updating Cabal
Config file path source is default config file.
Config file /app//.cabal/config not found.
Writing default configuration to /app//.cabal/config
Downloading the latest package list from hackage.haskell.org
Note: there is a new version of cabal-install available.
To upgrade, run: cabal install cabal-install
-----> Release the hounds! Installing application
Resolving dependencies...
cabal: Could not resolve dependencies:
trying: lol-0.0.0
trying: yesod-1.1.9.2
 !     Heroku push rejected, failed to compile Haskell app

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:nameless-savannah-3054.git'`

我的cabal文件就是yesod init生成的文件

对原因有什么想法吗？

编辑:我还应该提一下，它在OS上本地构建得很好。

使用以下构建包，而不是本教程中链接的构建包，修复了该问题：
