I’m running on MacOS 13.5.2, but started old and has been upgraded through the years (don’t know if that’s relevant but it might be). I’ve just installed crystal first via `asdf` and then, after that didn’t work, via homebrew.

In both cases, I’ve been trying to run a simple `puts "Hello, world"` via `crystal hello.cr` (and, later, via `crystal eval 'puts "Hello, World"'`). However, I keep getting this error:

```auto

```

Now, I know that `dsymutil` does not live in `/usr/local/bin`. It lives in `/usr/bin`. I see `/usr/local/bin` in my PATH but nowhere else in my environment variables. I don’t see it anywhere in homebrew’s Formula. I don’t know where this is being specified. The question is twofold:

1. Why is crystal assuming it lives in /usr/local/bin instead of trying to locate?
2. How can I change this assumption?

I think is failing because it tries to check if `/usr/local/bin/dsymutil` exists at all and failing in that check.

If you drop or tweak the order in `PATH` you should get pass this I think.

That being said, maybe `Process.file_executable?` should not raise in this case. Is there anything to say regarding the permissions on that folder?

The actual exception comes from `Crystal::System::File.info?` which by its very definition shouldn’t raise an exception. Looking at its implementation confirms this, and `Crystal::System::File.info` just wraps it and re-raises an exception.

Being unable to stat `/usr/local/bin` also doesn’t sound unusual to me as that’s generally a protected directory, but that makes me wonder how this issue hasn’t crept up before on MacOS when running anything with debug. 🤔

Ok, so running `PATH=/usr/bin:$PATH crystal eval 'puts "Hello, World"'` works, which is good to know.

But it does feel odd to have /usr/bin higher in the PATH than /usr/local/bin. Though, I guess, since I know basically nothing is using /usr/local/bin, it should be fine to muck around with the default PATH building in my shell. Ah, well. Thank you both for the answer!
