Ruby updates

[TheTechRobo]

I'm embarrassed about this, but I still use Mac OS X Lion... I just really like Aqua.
There's one problem... isn't the only way to update Ruby is with Homebrew?
Homebrew drops support for out-of-date OSes... like all the versions of Mac OS I have at home :)
Whenever I try to install, it shows this:
Anfunfun's-MacBook-Air:~ computer$ gem install iStats ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /Library/Ruby/Gems/1.8 directory. Anfunfuns-MacBook-Air:~ computer$ sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install iStats Password: ERROR: Error installing iStats: iStats requires Ruby version >= 1.9.3.

So in other words I'm stuck? Homebrew said it wouldn't have any support on Yosemite, and the install failed for.. even installing Homebrew on Yosemite. Doubt it would work on an even older OS.

MacBook Air (October 2010)
OS X Lion 10.7.5
Build 11G63

Thanks!

Try with more permissions: sudo gem install iStats

Okay, trying that...

Alternatively, you can avoid sudo by installing ruby to your home directory.

Install rbenv using brew. Install and enable any version of ruby, like 2.6.3. Installed versions are located in ~/.rbenv. If you install gems globally like gem install iStats, they will not need sudo, because they will be written to your home directory.
