Cabal getting installed in root directory instead of /home/vagrant directory using Vagrantfile

问题

THe below is the content of the vagrant file. When I run vagrant up command, it installs cabal as required but it is in the root directory. Hence, it becomes unusable. I want to update the cabal version to latest version using cabal update. But it is not happening.

Finally, in my VM, I have old version of cabal which comes with haskell-platform which is of no use to me. However, when I execute these commands separately by explicitly logging into VM, and not putting anything in Vagrantfile, it works and I get cabal version 1.22.6.0 which is what I need, but by using Vagrantfile. How do I make sure that cabal is not getting installed in the root directory ? Instead I think it should get installed in the /home/vagrant directory like this: /home/vagrant/.cabal/bin

I've personally had more luck configuring vagrant with ansible, but if you wish to do it this way, have you tried:

sudo -u vagrant cabal install cabal-install
