Uncaught Error: EEXIST: file already exists, mkdir 'C:\Users\jony\AppData\Local\Temp\linter-elm-make4760ZVKuSHmBWFXR\node_modules\electron\dist\resources\default_app.asar'

I'm using Atom 1.11.2 and Windows 10
This error _only happens when i use electron with elm_ - it doesn't happen when i use Elm alone in a project - to clarify:
This folder structure - doesn't give me any Atom errors - and the linter works fine by shows all Elm errors.
`
myProject

     -- elm-stuff
     -- elm-package.json
     -- Main.elm

`

_But the following folder structure:_
`
myProject

     -- elm-stuff
     -- node_modules  // as soon as i add the node folder my editor stops working and throws
     -- elm-package.json
     -- Main.elm
     -- other .js electron files...

`
_this error :_

Uncaught Error: EEXIST: file already exists, mkdir 'C:\Users\jony\AppData\Local\Temp\linter-elm-make4760ZVKuSHmBWFXR\node_modules\electron\dist\resources\default_app.asar'
Also, even if the Main.elm has Elm errors - it default's to No Issues green tag..

Here is an image with the error
And here, a faulty - no issues - green tag is shown

Can't be just an Electron problem either. The electron app - with no .elm - files works just fine.
It's the combination of both, that raises this issue.

Electron & Elm - truly is the best combination I've ever seen so far, I hope this issue is not something serious and it will get fixed soon :) Tank's a lot!

Hi! Can you also tell us your linter-elm-make settings, elm-package.json (specifically source-directories), and linter-elm-make.json (if existing)? Thanks!

[AionDev]

Linter-elm-make Settings :

- Settings: 
   -- Lint On the Fly - checked
   -- Report Warnings - checked
   -- Log Debug Messages - checked

- Keybindings:
    -- Enable -> Escape and Enter.. = ( the default ones..)

-- all the other are not selected..

elm-package.json :

{
    "version": "1.0.0",
    "summary": "helpful summary of your project, less than 80 characters",
    "repository": "https://github.com/user/project.git",
    "license": "BSD3",
    "source-directories": [
        "."
    ],
    "exposed-modules": [],
    "dependencies": {
        "elm-lang/core": "4.0.5 <= v < 5.0.0",
        "elm-lang/html": "1.1.0 <= v < 2.0.0"
    },
    "elm-version": "0.17.1 <= v < 0.18.0"
}

linter-elm-make.json - i don't have this file

Thanks for the fast reply 👍 !

I found another thing that can be helpful.
The Linter works with no problem if i disable "Lint On The Fly" option..
So the problem now becomes: Lint On The Fly + Electron package (in node_modules).. i'm still in the dark but maybe you find this more on point.

Unthil this get's fixed i will use the default linting on save. Good thing I'm able to continue the project now..

Hi @AIon-Gbbe, sorry for the late response.

What's happening in your case was that the library linter-elm-make is using to copy files was also looking at the files inside default_app.asar (it's an archive file https://github.com/electron/asar). I haven't dug deeper yet, but maybe the library treated the file like a directory and wanted to create a similar directory (mkdir) in the work directory.

I'm glad that you submitted this issue :-) While debugging, I noticed that non-elm files were also copied to the work directory. It should not try to copy default_app.asar in the first place 😝

Can you check if the latest version (0.17.8) resolves this? Thanks!
