Cannot install Crystal .pkg files completely broken on macOS.

[pateljoel]

I tried to install Crystal 1.16.1, specifically crystal-1.16.1-1.universal.pkg

and I get this error:

The command line gives me the same thing.

sudo installer -pkg ~/Downloads/crystal-1.16.1-1.universal.pkg -verbose -target /
installer: Error - Crystal can’t be installed on this computer.

I've tried searching what the issue maybe before submitting this issue to no avail on what could be causing this.

I installed other .pkg files just fine, but it looks like crystal's .universal.pkg installer is broken.

I would install crystal via homebrew but LLVM takes up massive GBs and way too much space on my machine just to install crystal, I do have ample space though but not to let LLVM take too much space.

Help would be appreciated.

Reproduce:

1. Download crystal-1.16.1-1.universal.pkg
2. Get past the macOS installer warnings in System Settings > Privacy & Security > Security > (Open Anyway)
3. Get to the installer screen and I am presented with the "Crystal can’t be installed on this computer." message.

You could try the tarball instead: https://github.com/crystal-lang/crystal/releases/download/1.16.1/crystal-1.16.1-1-darwin-universal.tar.gz
It should be the same thing, just without the automatic installer.

Have you tried the installer for any older version?

According to GitHub stats the pkg is barely downloaded for any release. So we might not have noticed if the build process for that got broken at some point.
Everyone seems to use the tarball instead 🤷

installer with -dumplog option might show more information why it's failing.
