目前,當我嘗試安裝GOA我得到以下信息:瞭解陰謀依賴消息
>sudo cabal install goa
Resolving dependencies...
In order, the following would be installed:
directory-1.1.0.2 (reinstall) changes: filepath-1.3.0.0 -> 1.2.0.1
process-1.0.1.5 (new version)
goa-3.1 (new package)
cabal: The following packages are likely to be broken by the reinstalls:

我的問題是,這是否意味着我現在有「文件路徑-1.3.0.0」作爲默認值,並陰謀(在 - 強制重新安裝)將會覆蓋這個並使「filepath-1.2.0.1」爲默認值?我有點困惑的原因是,當我在看的位置:
小集團/包/ hackage.haskell.org /文件路徑
我發現無論1.2.0.1 & 1.3.0.0存在。此外,該命令「陰謀列表文件路徑」表示兩個包安裝(請參閱「安裝的版本:1.2.0.1,1.3.0.0」,在下面):
>cabal list filepath
......

注意警告。當cabal說cabal:下列軟件包很可能被重新安裝破壞:「這意味着它們幾乎肯定會被破壞。 –
