GHC cabal安裝小村莊失敗並帶有一個模糊的錯誤

Question

我想在webfaction共享服務器上安裝一個Hamlet，這樣我就可以在那裏編譯和運行我的web應用程序。我正在使用Yesod來開發應用程序。

我設法從源代碼和引導程序cabal安裝編譯GHC 7。接下來，我做了cabal install hamlet，並預計它會工作。沒有運氣！

我從cabal/GHC得到以下奇怪的錯誤信息。任何人都可以幫我嗎？

好吧，我似乎已經解決了這個問題，並在這裏注意到它希望它可以幫助別人。

問題是webfaction不允許您執行存儲在/ tmp中的文件。來自cabal的錯誤信息非常令人困惑。

修復之前是在運行cabal安裝之前將環境變量設置爲您的homepath中的目錄（其中不存在此類限制）。我簡單地創建了一個別名 -

alias cabalinstall='export TMPDIR=~/tmp; cabal install' 

這可確保TMPDIR正試圖安裝任何小集團包之前設置正確。
