Won't install via homebrew

[brbatwork]

Used this for years on an older mac; now on my new mac I get:

What do I need to check to fix it?

[trodrigues]

I've had exactly the same issue.

The last time I had this, I found a tip elsewhere to run

RUBY=/usr/bin/ruby brew install gitsh

I tried that this time and it didn't work.

I then installed ruby with homebrew, and tried to do

RUBY=/usr/local/opt/ruby/bin/ruby brew install gitsh

and this also didn't work.

But if I download the package and run

RUBY=/usr/local/opt/ruby/bin/ruby ./configure

followed by make && make install everything works fine.

I'm still on High Sierra by the way.

Thanks for the reports. I haven't been able to reproduce on Mojave, but I'll see if I can find a Mac running High Sierra to try.

I'm getting the same issue on Sierra 10.12.6 with ruby 2.4.1. Any workarounds?

[gfontenot]

I'm seeing this on a new machine using Sonoma 14.3 as well. It does seem like the configure script is ignoring the path somehow?
