Stack setup failed with error 1

Adding set -x to the top of the shell script shows that this is the failing command:

stack /home/miles/.config/haskell-vim-now/scripts/setup_haskell.hs

I believe I have all the dependencies:

$ ghcide --version
ghcide version: 0.2.0 (GHC: 8.6.5) (PATH: /home/miles/.local/bin/ghcide) (GIT hash: 0ddc62fb96ada49d660382fbd91835f964c241ef)
$ hlint --version 
HLint v2.1.26, (C) Neil Mitchell 2006-2019
$ hoogle --version
Hoogle 5.0.17.11, https://hoogle.haskell.org/
$ stack ghc -- --version   
The Glorious Glasgow Haskell Compilation System, version 8.8.3

Not sure if it's an issue that ghc can only be launched via stack.

[begriffs]

Maybe the problem is that setup_haskell.hs calls stack internally with a shabang:
https://github.com/begriffs/haskell-vim-now/blob/master/scripts/setup_haskell.hs#L1

So invoking stack /foo/bar/setup_haskell.hs may be redundant? Perhaps the script should be run directly on its own...

I believe @p-alik is familiar with that section of code and may be able to investigate.

Installation succeeded on ubuntu 18.04. ghc v8.6.5 is only difference in my environment because installation of 8.8.3 failed despite allow-newer setting with

stack --version
Version 2.3.1, Git revision de2a7b694f07de7e6cf17f8c92338c16286b2878 (8103 commits) x86_64 hpack-0.33

I believe I have all the dependencies

setup_haskell.hs doesn't look for installed helpers. It overrides them heedlessly.

[saniac]

I also see this error on a more or less clean install of Ubuntu 20.04. Am too much of a noob to diagnose but happy to provide additional info about this system.

[p-alik]

@saniac, please provide:

• stack --version
• stack ghc -- --version
• stack setup --verbosity warning, which cause the error
  

  haskell-vim-now/scripts/setup_haskell.hs

  Line 102 in df31c3a

  stackSetupResult <- Turtle.shell "stack setup --verbosity warning" empty

[saniac]

Run in my home directory, I hope that's right.

stack --version
Version 2.3.3, Git revision cb44d51bed48b723a5deb08c3348c0b3ccfc437e x86_64 hpack-0.33.0

stack ghc -- --version

stack setup --verbosity warning

( doesn't produce any output.)

[p-alik]

Could you try to execute stack setup with --resolver please, which is used by

haskell-vim-now/scripts/setup_haskell.hs

Line 4 in df31c3a

--resolver lts-14.12

However on a new vagrant box ubuntu/focal64 I can't reproduce the issue:

vagrant@ubuntu-focal:~$ stack setup --resolver lts-14.12 --verbosity warning
vagrant@ubuntu-focal:~$ echo $?
0

[saniac]

stack setup --resolver lts-14.12 --verbosity warning
(no output)

echo $7
(no output)

My laptop has a fairly new Focal install. I've just checked my bash history to see how I got Haskell and stack set up, in case that's relevant.

I installed the haskell-platform. Then installed haskell-stack. Then executed stack upgrade.

[p-alik]

echo $7

echo $? prints last command exit status. If it prints 0 there is no issue and you could install by running ~/.config/haskell-vim-now/install.sh,. ~/.config/haskell-vim-now/ created by /tmp/haskell-vim-now.sh.

But also:

stack setup --resolver lts-14.12 --verbosity warning

echo $0
/bin/bash

Which is not 0.

I'm just theorising here, but I have bash-it installed. I wonder if something it does is interfering with the shell scripts. I'm just going to uninstall it and see what happens.

[saniac]

Update: removing bash-it did not make a difference.

[p-alik]

I couldn't reproduce the issue in any of on default installed shells bash, sh or dash. No issue even with bash-it. Maybe making stack more talkative can help. Please try

echo $SHELL
which stack
set -x
stack setup --resolver lts-14.12 --verbosity debug
echo $?
set +x # to disable set -x

[saniac]

Output attached.

[p-alik]

That's weird, stack setup --resolver lts-14.12 --verbosity debug exits with 0, but for stack setup --resolver lts-14.12 --verbosity warning with not 0? In this case that's an issue for stack team. Could you check exit code for --verbosity warning one more time please?

[saniac]

I'm sorry to have wasted your time, I'm an idiot who has not closely read instructions. I've reviewed carefully and realise now that sometimes I was typing "echo $0" not "echo $?".

$? is 0 consistently for both "stack setup --resolver lts-14.12 --verbosity debug" and "stack setup --resolver lts-14.12 --verbosity warning".
