.DS_Store in installed lib

[OrangeDog]

npm install [email protected] creates the file node_modules/extglob/lib/.DS_Store

I'm not using macOS so I'm pretty sure it's not at my end.

@vue/cli has this as a dependency in its dependency tree. Every time stuff changes there it happens. Not the worst error in the world, but one of those "really?" moments. This is still happening

Agreed, it's irritating that NPM picked up this file when I published the lib, despite always being ignored in .gitignore.

[djzara]

I noticed that when I went to investigate. I'm like...ok nobody actually leaves that in. And yeah, it's in there. Maybe got committed by mistake at some point? Who knows. Bet money if you send something you'll get the same error message you always get when something happens with the npm util when something goes wrong
"This is probably not a problem with NPM itself" lol

Remember that NPM doesn't care what is committed to git. It only zips up what you explicitly define in package.json.

I'm mainly thinking out loud, but wouldn't you still need it in there to keep NPM from picking it up when it pulls from the repository listed in package.json?

No worries! I don't mind the questions. Happy to help!

When you run npm publish, NPM doesn't check to see if a .git/ directory even exists (if the CLI does check, it's only to fill in some kind of details that might be useful for metadata, but it's not necessary). Also, if you specify files in package.json, then NPM will only include files specified on that property, while also ignoring any files ignored by .gitignore or .npmignore.

In any case, since the file is ignored, doesn't that address all of the scenarios you're asking about? What's more likely is that NPM's matcher (minimatch) didn't match the file. Perhaps this is a nuance caused by having a * before the . in *.DS_Store (fwiw that pattern was generated, and it should work just fine with a glob matcher).

My hunch is that NPM does not explicitly set minimatch's dot option to true, and instead they rely on testing the first character of a pattern to see if it's attempting to match a dot--which would be incorrect matching behavior for gitignore patterns.

[djzara]

That all makes perfect sense! I'm not in the npm package dev world so it's still got some intricacies I don't understand quite yet. That right there is gonna save some headaches. I never thought about the way the path is defined as being an issue anywhere, honestly, but it makes sense given that pattern in gitignore being kind of critical.

Much appreciated!!

fwiw I will republish to get rid of this file as soon as I have a chance

Everytime I install something with brew this bug pops up like this:

Error: Permission denied @ apply2files - /usr/local/lib/node_modules/expo-cli/node_modules/extglob/lib/.DS_Store
Requirements installation failed with status: 1.

Then I need to manually delete this file and run again.

Damn that's irritating. Sorry you have to do that. I've been swamped, I'll try to push up a patch to fix this.

Here because of the brew apply2files issue in brew. It suffices to delete all of the .DS_Store files in /usr/local/lib/node_modules/:

find /usr/local/lib/node_modules/ -name .DS_Store | while read x; do echo "$x"; sudo rm "$x"; done

@jonschlinkert the simplest way to fix the module is to change the files entry to be a glob:

https://github.com/micromatch/extglob/blob/master/package.json#L23

  "files": [
    "index.js",
    "lib/*.js"
  ],
