Unable to debug after setting up the configuration

[fengkeyleaf]

I set up the configuration according to the instructions, but when I run the program, it showed the following message in the DEBUG CONSOLE:

Laded package environment from C:\Users\fengk\OneDrive\documents\computerScience\RIT\2021 fall\myProject\dist-newstyle\tmp\environment.-12116.ghc.environment.x86_64-mingw32-9.0.1 GHCi, version 9.0.1: https://www.haskell.org/ghc/ :? for help target ｡ｮfall\myProject｡ｯ is not a module name or a source file ghci>:set prompt "<>\nH>>= " H>>= :set prompt-cont "<>\nH>>= " H>>= :dap-launch ... unknown command ':dap-launch' use :? for help.

And I couldn't debug with step over and so on.

Hi.

It seems like you are not using ghci-dap. Could you confirm that haskell-debug-adapter and ghci-dap command is on your PATH environment?

command prompt
> ghci-dap --version
[DAP][INFO] start ghci-dap-0.0.XX.0.
The Glorious Glasgow Haskell Compilation System, version 9.X.X
>
$ haskell-debug-adapter --version
VERSION: haskell-debug-adapter-0.0.XX.0

Yes, I have those two on my PATH environment:

So I don't know what's wrong with my environment.

Hi.

On "myProject", ghc-9.0.1 is used, but ghci-dap is installed with ghc-8.10.4. In "myProject" folder, could you reinstall ghci-dap and haskell-debug-adapter, for ghc-9.0.1.

Are you using cabal? (or stack)

Regards.

I'm using cabal, but how do I reinstall ghci-dap and haskell-debug-adapter for ghc-9.0.1. in "myProject"? I used Chocolatey to install and GHC and cabal but there was no specific version designated.

Could you confirm the PATH environment ? In below case, "C:\Users\phoityne\AppData\Roaming\cabal\bin" should be on the PATH.

c:\temp>cabal install ghci-dap haskell-debug-adapter --overwrite-policy=always
