使用Vagrantfile将Cabal安装在根目录而不是/ home / vagrant目录中

本文介绍了使用Vagrantfile将Cabal安装在根目录而不是/ home / vagrant目录中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 下面是流浪文件的内容。当我运行 vagrant up 命令时，它会根据需要安装cabal，但它位于根目录中。因此，它变得不可用。我想使用 cabal update 将cabal版本更新到最新版本。但是它没有发生。

最后，在我的虚拟机中，我有旧版本的cabal，它带有 haskell-platform

解决方案

我个人有更多的运气配置流浪汉，但如果你想这样做，你有没有尝试过：

sudo -u vagrant cabal install cabal-install

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

解决方案

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
