Same problem with iStats

Hello, OSX catalina 10.15.7 on an unsupported Macbook 2011 (via dosdude's catalinaPatcher) here. I know nothing about ruby, so bear with me.

Don't use sudo on macOS. Either use these env variables to instruct the gem command to install somewhere in your user directory: https://stackoverflow.com/a/27677094/322020 Or better install Homebrew and do brew install rbenv and read docs abut using rbenv that will then install gems somehere in ~/.rbenv.

Same problem on Big Sur. I use the gem install iStats and get the same output like above. But I have added the export PATH="$HOME/.gem/ruby/2.6.0/bin:$PATH" export GEM_HOME=$HOME/.gem to my .bash_profile.

Same problem on Big Sur. I use the gem install iStats and get the same output like above. But I have added the export PATH="$HOME/.gem/ruby/2.6.0/bin:$PATH" export GEM_HOME=$HOME/.gem to my .bash_profile.

You can do these to make it work:

First, don't use the gem that Mac provides you, if you use this one, You need 'sudo', and get error.

brew install ruby

Run it to install a gem.

Then add this ruby path and this gem path to your .zshrc files, in my Mac is like this

export PATH="/usr/local/opt/ruby/bin:$PATH"
export PATH="/usr/local/lib/ruby/gems/3.0.0/bin:$PATH"

It may be different in your Mac ! And The istats will install in /usr/local/lib/ruby/gems/(your gem version)/gems/

Finally, run

source ~/.zshrc
gem install iStats
istats

You can find it works well.
