Haskell包構建錯誤

Question

我創建了一個cabal沙箱，我試圖在我的OSX上構建hakyll Haskell包，但在包temporary-1.2.0.2上發生構建錯誤。可能是什麼原因？
小集團版本低於1.20
生成錯誤是：

Answer 1

這是由於一個錯誤的「臨時」包：https://github.com/batterseapower/temporary/pull/12

由於維護不響應，有沒有一直是對hackage的臨時更新，並且有人創建了一個暫時的分支。

從我可以告訴'臨時'依賴是來自pandoc和pandoc-citeproc。我能夠通過執行以下操作來安裝hakyll，這很不方便，但爲我工作，不需要下載和修改一堆軟件包以使用'temporary-rc'而不是'臨時'。

經由 cabal get temporary-rc
1. 編輯臨時rc.cabal和
2. 下載臨時-RC到一個臨時文件夾改變 「名：」 字段（第一行）從 '臨時-RC' 到 '臨時'
3. 我使用沙箱，所以如果你是，做cabal sandbox add-source <path/to/temporary-rc>（臨時-RC文件夾中的最後一步temp目錄）
   • 如果你沒有使用沙箱，我想你可以從做cabal install temporary-rc文件夾將其安裝到您的用戶包-db中。我沒有測試過這個。
4. 正常安裝hakyll，它應該拿起修改過的'臨時'軟件包。

如果你想在家裏跟隨，有一個thread on haskell-libraries討論的情況。
