ESLint behaves differently on different system #4540
Description
Recently, @mcmire put up #4537 to address some lint errors he observes locally (ref: #4537 (comment)). These began to appear on his system after my PR #4521. I am unable to observe the same errors. On the other hand, I observe no less than 44 errors from the root yarn lint on current main (b7fa70e):

Comment thread where two more people experienced this: #4506 (comment)
In my case, it was something about my local dev environment that was off. Unfortunately, I didn't document the fix that ended up working, and haven't been able to repro the bug.
It wasn't a complex fix. It might have been removing
node_modulesand reinstalling dependencies, removing eslint cache, or something of the sort.rekmarks commentedon Jul 19, 2024
I did several variations of the following to no effect:

ESLint succeeds in fresh clone of the repo, but only in a different directory on my system. If I delete my original copy of the repo and replace it with the freshly cloned copy, it starts failing again. There are no
.eslintconfigfiles in any parent directory, and the Node versions are the same. This is definitely local to my system, but I don't understand the hell that I'm in.I'll leave this open for other people who are debugging their local ESLint behavior.

I've just run into this problem again. There are two lint issues I see locally. I have tried all of the solutions posted above to remove them without success. I've attempted to fix these here but we shouldn't have to do this: #4545
mcmire commentedon Oct 23, 2024
Still running into this problem as of October 2024 — this time it's the
@typescript-eslint/restrict-template-expressionthat's failing locally for me (but obviously not failing in CI, otherwise CI would be failing onmain). This ESLint rule has failed numerous times in the past for me and is rather unreliable, so it's not a surprise, but still, rather annoying.mcmire commentedon Jan 9, 2025
I've just merged in #4727 which bumped all of the lint packages. I ran
yarn lintlocally and no longer see the false positive I was seeing before (not the one I mentioned above, but a different one with KeyringController). So it's possible that this problem is now solved, but we should keep an eye on it for now.mcmire commentedon Feb 4, 2025
With the upgrade to the ESLint 9, the false positives around the
typescript-eslintrules seem to be gone (in fact there are tons ofeslint-disablelines we can now remove). I think the inconsistencies in behavior we were seeing before are basically gone as well. @mikesposito did report an issue in a recent PR, but I think this was due to an outdated ESLint cache file rather than a bug in any one rule.I'm going to close this ticket for now and we can reopen it if we see it again.
