[muhajirdev]

Anyone how do I solve this?
Do I need provide any other information?

[jneira]

Hi! The code is assuming the environment variable PATH is set. What is your system?
It should not fail in this case but it is weird that the variable dont ever exist in the environment.
As temporary workaround you can try set the variable (with an empty value) before calling the script.

[jhrcek]

What operating system are you using?
It seems that you PATH environment variable is not set, not sure why. My understanding is that the installation script is trying to check if cabal is installed on your system (by checking for presence of "cabal" binary on your PATH). If I were you, I'd first start to investigate why the PATH variable is not set in your environment.

[jneira]

In any case i've done a patch to ignore the $PATH env var if it is not set. Unfortunately the lookupEnv :: IO (Maybe String) function throws an error if the env var is not set, instead return Nothing (as i expected)

[muhajirdev]

I am using Mac OS catalina.

I tried to echo $PATH

it gives me this

[fendor]

While this is a separate issue, do you have nix installed on your system? Or maybe in the config.yaml enabled nix although nix is not installed?

[jneira]

@muhajirdev hi! the pr is merged and it should fix the error, unfortunately i can test it myself cause it is not reproducible in windows systems
could you try again to install cabal after update the hie project to lastest master?

[jneira]

Maybe we should continue investigate why the $PATH env var is not accesible through System.Environment.lookupEnv but it seems it is not related directly with hie itself (maybe it is defined in ~/.bash_profile but no in ~/.bashrc?)

[muhajirdev]

Okay, I tried to git pull.

Still giving me this.

But I tried build-all. It doesn't gives any error.

[jneira]

Well, that is really weird. Thanks for test, it is hard to fix a bug that is not reproducible in local.
Just in case, could you check if you local copy contains the commit with the fix (c253cbb)?
If it is so the only cause i can think of is the IOException throwed is not a doesNotExistError but that would be really strange cause the message is exactly the same.

[pcaisse]

I'm running into this same issue (and I have c253cbb). I'm very new to the Haskell ecosystem, so bear with me.

I installed ghc and stack successfully but when I ran stack install.hs cabal-ghcs I saw that I had an older version of ghc installed (8.0.1). I then went and installed the latest and greatest (8.8.1) according to these instructions (I'm on Debian Stretch) and then I started getting the error.

In case it helps:

    Ignore the stack PATH fix if the env var is not set

[fendor]

Note, hie does neither support GHC 8.0.1 nor 8.8.1 and the installation script should not actually show these as an option. I will open another issue for that.

There is a path variable defined though, right? So, echo $PATH actually exists?
