Question

我跑了

apt-get install haskell-platform
cabal update

现在我尝试使用

升级cabal版本

cabal install cabal-install

但它失败了，我得到以下错误：

正如我所说，这是一个全新安装，所以我不知道如何进行任何更改。当我安装与最新的cabal-install不兼容的haskell时，似乎安装了bytestring包的一个版本。在某种程度上，我可以选择我想要开始使用哪种阴谋，或者我该如何应对这个问题？

我应该注意到我之前安装了haskell-platform但我跑了

apt-get purge haskell-platform
apt-get autoremove

在重新安装之前

安装cabal-install时，字节串类型失败
