Not working in macOS 10.15 Catalina

[Liampor]

Hello,

I have updated to macOS 10.15 Catalina, then iStats does not work any more.

> iStats
zsh: /usr/local/bin/istats: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: no such file or directory

It seems, Rubyl are not included in new macOS.

my Ruby version

>ruby -v
ruby 2.6.4p104 (2019-08-28 revision 67798) [x86_64-darwin18]

Thanks

$ brew install ruby iStats

Try reinstalling the command line tools with xcode-select --install.

Did you try reinstalling iStats? The error is looking for for a ruby executable in the 2.3 folder but from your ruby -v it looks like you have 2.6 installed.

I have tried "sudo gem install iStats" and brew install ruby... not working

I think iStats needs ruby 2.3， but new macOS remove the ruby 2.3 and my user-ruby is Ruby 2.6

[Chris911]

Try gem uninstall iStats and then gem install iStats

[Liampor]

Try gem uninstall iStats and then gem install iStats

still...

[Chris911]

Ah try istats all lowercase instead of iStats.

same error :-)

[Chris911]

I don't know then. Still find it weird that the error is for 2.3 and you have 2.6 installed. I just uninstalled and reinstalled on my machine running Catalina and have no errors. I didn't have to use sudo.

thanks, use "gem install iStats" it gives more errors

@Liampor Inferred from your log, take a look at /usr/local/bin/istats, update first line to 2.6 (or the output of which ruby) maybe can solve this:

➜   which ruby
/usr/bin/ruby
 ➜  cat /usr/local/bin/istats
#!/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/ruby

#!/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/ruby

gives

@Chris911 @phyng

Finally solved! Thank you all!

I have two Ruby path:

1. /usr/local/opt/ruby/bin/ruby (default, installed by Homebrew)
2. /usr/bin/ruby

If set default ruby-path to /usr/bin/ruby und reinstall iStats by sudo gem install iStats then edit /usr/local/bin/istats headline to #!/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/ruby

it works fine !

@Liampor I have same problem, two Ruby path; and I don't know how to set default ruby-path

@Liampor I have same problem, two Ruby path; and I don't know how to set default ruby-path

Step 1:
set ruby-path to /usr/bin/ruby
to do this, you can edit your Terminal profile，for example in ZSH
export PATH="/usr/bin:$PATH"

Step 2:

Quit Terminal and reopen.

run which ruby If anything is right you will see /usr/bin/ruby

Step 3:

reinstall iStats

uninstall: sudo gem uninstall iStats
then reinstall: sudo gem install iStats

worked!

If you want to use other Ruby-path, you can edit the terminal profile later.

ps. 用我的蹩脚英语和中国人对话好奇怪。。

Hi all,
I also got same trouble and reached here.
@Liampor, thank you for giving me the answer!

Did you try reinstalling iStats? The error is looking for for a ruby executable in the 2.3 folder but from your ruby -v it looks like you have 2.6 installed.

I think iStats needs ruby 2.3， but new macOS remove the ruby 2.3 and my user-ruby is Ruby 2.6

I installed ruby 2.3 via mac ports and changed the default ruby and succeeded to install iStats.

% sudo port install ruby23
% sudo port install ruby_select
% sudo port select --set ruby ruby23
% sudo gem install iStats -n /usr/local/bin 

environment : Mac OSX catalina (10.15.7)

When using Homebrew I recommend installing custom Rubies via brew install rbenv and following the instructions.
