How to install Haskell Stack locally?

Question

I am working on my school server and I need to install the Haskell stack. In the README file and on the website, I might not find how to install locally. What if I am not a sudo user?

You do not need superuser privileges to set the stack; You can also install it in your own home directory. All you need for this is a GMP Linux system (which GHC depends on a very fundamental level). If GMP is not installed - administrators really do not have to worry about installing it.

The Haskell stack is successfully installed using the instructions in the Documentation here .

As with "sudo user", the sudo gives the user superuser privileges by flipping mode bit . Details about the mechanism can be found here.

Problem in your case, it may be the reason that in school networks, " users are not allowed to use sudo for security purposes, and therefore either administrators must provide their account privileges, or they must install the Haskell stack themselves. If this is part of the job, administrators You don’t have to worry about it, but you should inform the administrators about it, after which you can use it comfortably .

If the above steps are not possible, I suggest you try the Haskell stack in your personalized account on the device. You can even try cloud services like Cloud9, Nitrous and others. An incredible reason may be that you are not using the Haskell stack properly.

Note I have been using the Haskell stack for some time, so I can conclude that it works.
