What is the stack version you are using ? The latest one is stack-1.9.3. It seems you have 1.1.2 which is quite old. Can you install the latest one ?

Install instructions: https://haskell-lang.org/get-started

[qrilka]

I think the version 1.1.2 comes from the current Debian stable - https://packages.debian.org/stretch/haskell-stack and I see no versions in backports for it

[mihaimaruseac]

@jganetsk try stack upgrade and then probably you also need to set PATH to also include ~/bin/ or something (see the output of stack upgrade, it tells you where your new binary gets placed).

[qrilka]

@mihaimaruseac but isn't stack upgrade shown in the staring description of this issue?

[mihaimaruseac]

Oops, you're right. I just skimmed through the description when I came back to the tab.

@jganetsk then, I think you'd have to use the wget .. | sh line from https://docs.haskellstack.org/en/stable/install_and_upgrade/

Closing due to lack of response

I just encountered the same issue right now. Same error message. stack upgrade says it is downloading version 2.3.3 but when I call stack --version it is still an older one.

calling which stack shows that it is indeed looking at .local/bin/ for the executable.

I believe there is some OS side caching involved. Opening a new terminal session after that solved the issue. :)
