I can also confirm that Elm 0.19 elm init
results in the following error.
OS: Windows 10 version 1803 (OS Build 17134.285)
Access violation in generated code when reading 000000000f841bb6
On my MacBook, it works fine. I'd be glad to help post some other info if needs be. Thank you for the great work Elm team. Loving the simplicity of Elm. Elm newbie here.
I can also confirm that installer for windows 0.19.0 results in above error. I had to use Windows Subsystem Linux with Ubuntu on to install Elm 0.19.0.
Same issue for me. I had Elm 0.18 for windows installed and working fine. Then uninstalled everything and started from a clean slate with Elm 0.19 for windows. Any command in the repl gives me the access violation error. Happy to provide system details to help troubleshoot this. So interested to learn more Elm and stopped in my tracks for now
Update: Elm REPL and elm init work fine for me if I run the commands from a regular (not elevated) command prompt. It is only when I run from an Admin command prompt that I get the access violation. I tend to run from an Admin command prompt to make life easier for the other languages and frameworks I use. Given that the Elm installer asks for elevated privileges, I assumed elm itself would work under elevated privileges. I guess not. Curious if this fixes the issues for @soelinn @Worble or @bbecker-inlogik
@phmiller Unfortunately, this issue still occurs for me regardless of elevated command prompt or not, tested on both cmd and powershell. @bbecker-inlogik Do your elm commands work on WSL? I was able to install it, however the commands are not only very slow, but still also error out (and once also bluescreened windows for me)
Thanks @phmiller. It does work for me from windows command prompt non-admin.
@Worble, I had a freshly installed Ubuntu LTS on WSL, did apt-get update and then installed elm and latest nodejs to get it working. You might try updating your node to latest?
@bbecker-inlogik Ah, I didn't think about updating node. It now works on WSL, although it is still rather slow. Thanks!
Same here, get the error with elm init
and elm make
. Access violation in generated code when reading 000000000f841bb4
OS: Windows 10
I'm also experiencing this issue as of 0.19 when running from an admin terminal, and can confirm that it does work when running from a non-elevated terminal.
I completely wiped my PC and started from scratch, installing windows 10 and elm. This fixed the issue so clearly something else was getting in the way.
Update: Installed docker, visual studio 2017 and enabled IIS and BAM: Access violation in generated code when reading 000000000f841bb4
This is occurring on my home pc, work pc and build server. I'm wondering if it's a haskell compiler issue.
Recompiled with GHC 8.4 by upgrading language-glsl
to >= 0.0.2 && < 0.4
. Get the same error.
I think it's a ghc error. I run
stack init
stack build
stack ghci
And I get Access violation in generated code when reading 0000000004b5b91e
. It's a shame because this seems like a fairly common error and I'm guessing it's affected other people on windows who are running other haskell apps.
Alright so it certainly looks like a GHC problem. As a workaround, I rebuilt the elm compiler using GHC 8.0.1, making a few necessary code changes for the old GHC to work, and low and behold no more access violation issues!
For everyone in this thread and anyone in the future reading this, you can download the patched version here.
@Worble you can close the thread if you'd like, as it's an upstream issue.
Just installed elm today and having the same issue. Is it not been patched in the official installer?
@Tvde1 not yet. I think it's been fixed in GHC so expect it to be fixed in the next release. In the mean time try my patch.
Your patch fixes it. Thanks!
Hi. Is it still not fixed? Also, it seems like @Kurren123 's patch is not working for me. Reinstalling elm compiler also didn't solve the problem.
upd: tried to run it from non-admin terminal and it worked....
Are you still using the .msi installer? It's out on npm now, and that one works fine for me.
Can confirm I still get the same exact error when running what is currently the last version of elm on npm (0.19.0-no-deps) in a command prompt in admin mode:
C:\emgsgit\derp (derp@1.0.0)
λ npm install elm --save-dev
> elm@0.19.0-no-deps install C:\emgsgit\derp\node_modules\elm

Hello! Elm projects always start with an elm.json file. I can create them!
Now you may be wondering, what will be in this file? How do I add Elm files to
my project? How do I see it in the browser? How will my code grow? Do I need
more directories? What about tests? Etc.
Check out <https://elm-lang.org/0.19.0/init> for all the answers!
Knowing all that, would you like me to create an elm.json file now? [Y/n]: Y

This is quite annoying. Any clue if this will be fixed anytime soon?
@Worble may I ask why this was closed? Has it been resolved?
I had believed it to be fixed, or at the very least the npm binaries seemed to work regardless, but I can re-open it if it's still an issue.
@aparent-emgs have you tried my patch?
I was really trying to get the npm version of Elm 0.19 to work, as I need to still be able to use the 0.18 version (for older projects) which I installed with the installer back in the day, and which currently sits in my PATH. I wish to be able to use both (0.18 globally, and 0.19 locally through npm scripts), without having them collide with each other.
And yes @Worble, clearly, the issue is still present with any official version of Elm right now (I have also tried the installer on the official website, I get the same result). I feel like if the fix is as easy as rebuilding the compiler with a different version of GHC, why hasn't it yet been included in a bugfix? I don't think this should be left as is.
For now, I found a work-around which is to execute this before running any Elm commands in the command line, and it seems to work for me.
set __COMPAT_LAYER=
@aparent-emgs I've released an npm version too which I am using right now.
As for why this is being left as is, I believe NoRedInk are using linux for development which is why this bug isn't business critical for them.
I have this issue, after updating windows 10 some time this week. I only get this issue I run it from the git bash terminal though and not from cmd.
I installed elm from the installer, and not from npm.
@Neppord try my patch
I have the same problem when I run "elm init" in VSCode's terminal. But I when use Windows Terminal ( cmd from Run... ) I have no problem. ( I use Windows 10 64-bit ) and elm 0.19
the "vscode terminal" is not really the best reference here and that's certainly not elm's fault.
https://code.visualstudio.com/updates/v1_36#_launch-terminals-with-clean-environments
Same issue when running in cmd via IntelliJ's 'Terminal' pane... no issues with running directly via a normal cmd prompt.
Given that it is the same issue for both VScode and IntelliJ's terminal... I would say it might be something worth looking into from the Elm side.
@Stefan-Z-Camilleri @theparitt @Kurren123
Does it still happen with elm 0.19.1?
Hi, if this error still happens with GHCs newer than 8.4.2 please file a bug report and I will take a look.
If using newer GHC also try compiling elm with -rtsopts
and calling it with --install-seh-handlers=no
to see if that works around the issue.
Hi there, after upgrading to elm 0.19, attempting to do elm init causes this error message:
I can ignore this and continue with ‘n’, opting to make the elm.json myself, except that
elm make
gives the same error and code when trying to run it on Main.elm with any valid elm contents (for example, copy and pasting the code from https://guide.elm-lang.org/).elm repl
gives the same error when trying to run any code as well.I was originally using elm 0.18 installed using npm, so I uninstalled that and reinstalled 0.19 with the windows installer to make sure it wasn’t causing any issues and the error still persists.
I am using Windows 10 version 1703, OS build 15063.1266. This is a work machine behind a corporate proxy, and I can confirm a colleague who previously had no version of elm installed also has the same issues as I do.
