Install fails on 10.4.11

[ltpitt]

Hello there,

I write from the past :)

I tried installing this nice software on my eMac using 10.4.11.
I installed ruby via homebrew:
ruby 2.4.1p111 (2017-03-22 revision 58053) [powerpc-darwin8.0]

And tried the command in README.md to install:
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

And then gem install iStats or sudo gem install iStats but I got error anyway:
Building native extensions. This could take a while...

ERROR:  Error installing iStats:

Is there any hope for my dinosaur or I'll have to write my own little stats script?

Thanks for your time and help.

Have you tried (re)installing the xcode command line tools with xcode-select --install?

[ltpitt]

If I try that command I get:
-bash: xcode-select: command not found

I tried removing my xcode and reinstalling from scratch but the error remains identical.

The command provided in your README.md:
sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install iStats

returns:
sudo: ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future: command not found

So I tried to do two commands:
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

and then:
gem install iStats (with or without sudo)

But I always get:

Building native extensions.  This could take a while...

Thanks for your kind help!

I had this issues and fix with following.

Installed zsh
brew install zsh

sudo gem install iStats gave me this

I did the following which got iStats installed:
brew uninstall ruby

then : brew install ruby

then : export PATH="/usr/local/opt/ruby/bin:$PATH"

then : export PATH="/usr/local/opt/ruby/gems/3.1.1/bin:$PATH"
note - your version may depend. Please cd to /usr/local/opt/ruby/gems/XXXto find version that you have.

then : source~/.zshrc

then : sudo gem install iStats
