Hi, I’m using MacOS 10.15.4 and new download of ST. When running ST I get repeatedly this message:
Backend configuration: "Local hsdev"
Incompatible hsdev, detected version 0.0.0.0
Version should be ≥ 0.3.3.0 and < 0.3.4.0
I’m and old geezer trying to use ST to start learning Haskell, and am rather dense with ST and backend installation things, so all attempts at help are welcome. Thank you!
P.S. I used Haskell platform to install Haskell.
And I have updated my Bash to the most recent vrsion, 5.0.18(1), if that means anything.
I have not found in ST any mention which version it is, but i downloaded it yesterday.

That error is coming from a plugin you have installed. You can get the version of Sublime Text under the menu Sublime Text > About
Thank you for your answer,
ST version is 3.2.2, Build 3211. (While the error msg was displaying the About menu choice was disabled, thus I did not see it earlier. sorry.)
The plugin must be the Haskell plugin. But what should I do to get rid of these messages?

Which packages did you install? You can see the list of installed packages by running “Package Control: List Packages” from the Command Palette (accessible by pressing cmd+shift+P)
Only Subime-Haskell is installed. v2.2.0; github.com/SublimeHaskell/Sublime Haskell it says.
Hi @Libertinus, I don’t use that package personally. From what I can gather is that you need to install tooling around the Haskell language, like stack or cabal. Does that help? https://github.com/SublimeHaskell/SublimeHaskell#required-before-you-install-sublimehaskell
Hi, @rwois,
I have Haskell platform installed, which was an ordeal. (Before Haskell platform installation I tried Haskell installation with stack several times and a pain in the butt it was, I never got it working.)
Now I have this Haskell platform installation working ok, and I’m not that eager to start messing with stack again.
What I mean, I’m an old geezer, and some things easier to other people - like using github - are quite a mystery to me.
In short, I’m not quite sure if I understand what you’re suggesting I ought to do. Sorry to be such a dense customer…

I followed the link, and first uninstalled 8the relevant parts of) Sublime text. Then installed the backend. Then re-installed the SublimeHaskell.
Now I get this error message:
Backend configuration: "Remote hsdev@localhost:4567"
Incompatible hsdev, detected version 0.3.4.0
Version should be ≥ 0.3.3.0 and < 0.3.4.0
I am slowly going mad. Slowly but quite unavoidably…

it looks like hsdev wasn’t installing with latest GHC as far back as 2018: github.com/mvoidex/hsdev/issues/91#issuecomment-419731848 and the project doesn’t look terribly active to me overall
mpickering.github.io/ide/posts/… looking at this article, hsdev isn’t even mentioned as a valid IDE plug-in anymore, so I’d recommend ditching it in favour of a newer plug-in, OR installing an older version using Stack, if you must
Note Sublime Text comes with Haskell syntax highlighting. Unless you’re specifically looking for advanced auto-complete you don’t need a package for this. In any case it looks like your options are to use a different package or an older version of Haskell.

Thank you!
It appears my best bet is just uninstall SublimeHaskell and go with “plain” Sublime text.
Do I need to uninstall hsdev? Do i need a newer IDE-plugin, and if so, which one would you recommend. My aim is just trying to teach myself Haskell, just to keep my my brain from rusting over too fast.

I don’t use Haskell, so I don’t have any recommendations. I’ve never found IDE-like functionality particularly useful and for learning I’d personally consider it a negative. If you do want IDE-like functionality a good thing to look at would be LSP.
@bscaaf,
Thank you for your insight!
I will make do without an IDE-plugin.
Cheers,
L
