Question

我错误地从我的root directoty中删除了/root/.cabal/，当我尝试重新安装它时，我得到了这个输出：

faiz:~$ sudo cabal install pandoc --reinstall

In order, the following will be installed:
pandoc-1.14.0.4 (reinstall)

如何重新安装pandoc？我还想知道从root命令行（＃）安装pandoc（使用cabal）并使用sudo命令安装它有什么区别？（sudo cabal安装pandoc）

解决！

由于我删除（删除了）/root/.cabal/目录（错误地），我的系统仍然可以检测到其他一些包在那里，结果抱怨系统已经拥有所需的包和文件。这是因为/root/.ghc/文件夹仍然存在。删除此文件夹，两个相应的本地文件夹~/.cabal和~/.ghc并使用cabal install pandoc解决了我的问题。

如何在删除.cabal后重新安装pandoc？
