Getting an "illegal instruction" error

[ThinkByDesign]

What were you trying to install (or what else went wrong)?

curl -sS https://webi.sh/nerdfont | sh

What exactly did you do?

I ran "curl -sS https://webi.sh/nerdfont | sh" as instructed on this page: https://webinstall.dev/nerdfont/

What went wrong?

Here's the output from the command:

I realized after submitting that this is probably a case where another project is using this project, so I've submitted the bug there. (ryanoasis/nerd-fonts#1522)

It's the other way around. Nerd Fonts is not using Webinstall - but Webinstall uses Nerd Fonts artifacts.

I would strongly recommend to use one of the officially mentioned Nerd Font installation methods:

https://github.com/ryanoasis/nerd-fonts?tab=readme-ov-file#font-installation

Also ... Webinstall installs a very old version of the font... Currently Nerd Fonts in on v3.1.1, and see here:

They do it on purpose, according to the commit message but do not document it anywhere.
Also no reason is given. ¯\_(ツ)_/¯

[HacDan]

Looks like NerdFonts was pinned at v2.3.3 in response to some repo restructuring around the time that v3.0.1 of NerdFonts came out. This is referenced in issue #606. From what I can tell, this was put in place as a stop gap and not revisited. At least that's how the issue and subsequent PR reads. I was not apart of said discussion, however, so I may be off base. @coolaj86 may be able to shed more light on the subject.

This installer should probably be revisited to make sure we're installing the latest release of NerdFonts.

As for the issue at hand, I'm not able to reproduce on Linux or MacOS Sonoma in ZSH. What shell are you using @ThinkByDesign?

Something to try, however, would be to run

webi webi

to make sure you have the latest version of webi installed, in case you had an older version from a previous webi install.

We have two independent issues here:

• sed illegal instruction
• NerdFont installer is old

sed Illegal Instruction

@ThinkByDesign Seeing that sed has illegal instructions makes me think that you're using brew, and that something installed sed, and that a recent upgrade didn't go well.

command -v sed

macOS sed is located here:

/usr/bin/sed

macOS sed is POSIX-only, and doesn't even have a version:

sed -V

sed: illegal option -- V
usage: sed script [-Ealnru] [-i extension] [file ...]
	sed [-Ealnu] [-i extension] [-e script] ... [-f script_file] ... [file ...]

To fix that I'd recommend that you install brew conflict-free: https://webinstall.dev/brew

Brew has official instructions for how to install conflict-free, but they don't do it by default - ostensibly because they can't generically "bottle" up many of the C libs and apps, so it makes the install process slower for old code that relies on hard-coded paths (though I don't think I've ever had any issues directly related to conflict-free installs). The webi brew installer automates those instructions.

NerdFont installer installs an old version

I would accept a PR for a fix for this, but I don't think I'll have the time to invest in it otherwise.

If you don't care about installing NerdFont in an automated fashion, then doing the download and figuring out the right path and such to put it in is going to be the best bet.

If you do want to be able to install it in an automated fashion, I'd be willing to help to get it on Webi, but I myself only use it to get some folder icons and whatnot with lsd.

[coolaj86]

I'm going to close this out since I believe it's related to a system tool that's broken the default macOS installation, and not anything to do with Webi (nor anything that Webi can fix or advise on in an automated fashion).

However, we can reopen this if that turns out not to be the case.

Just to mention, this does not look like a typical Apple-sed versus normal-sed problem

     72256 Illegal instruction: 4  | sed "s:^${my_rel}:~:"

s/^xxx/~/ is a perfectly valid sed instruction for all seds. The contents of my_rel must be strange (contain characters that mess up the sed command).

I assume my_rel and my_abs contain some paths fro the user setup. Probably the path in this concrete situation contains some regex control characters and there is no code to fortify the assembled sed command (obviously, because the env var is used directly).
On the other hand I can not imagine any contents of my_rel that would cause the encountered error message. And that error message does not seem to be a sed error message. ... Is 4 the exit code or the sed call? Who knows.

IO error? Points again to some peculiarity of the user setup.
