Mojave compatibility issues

[KernelPanicAUS]

This gem seems to have some compatibility issues with Mac os x Mojave.

$ sudo gem install rubocop

current directory: /Library/Ruby/Gems/2.3.0/gems/jaro_winkler-1.5.1/ext/jaro_winkler
/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby -r ./siteconf20181104-27213-qfkou.rb extconf.rb

make failed, exit code 2

Any ideas how this can be fixed?

Thanks for reporting, unfortunately, I am not able to reproduce with ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin18]. Can you give more details about your environment?

It may have something to do with building environment. I wonder if you are able to install any C-extension like nokogiri? For example gem install -f nokogiri.

[KernelPanicAUS]

that seems to have blown up as well

I'm using a new Mac and have only just upgraded to Mojave, so its a very clean environment and have not installed these gems at all prior to the upgrade.

I have double checked and I definitely have the xcode command line tools installed...

I'm also having this issue. I have Xcode Command Line Tools installed. Related to https://github.com/rubocop-hq/rubocop/issues/5989.

It happens when I try to install either rubocop or jaro_winkler.

rubocop installation error


jaro_winkler installation error

It seems like a lot of people are affected by the issue.

Would be nice to see a fix in the near future. Thanks

@rodrigobdz The images you gave does not contain informations, you have to provde the contents ofgem_make.out file. Since I am not able to reproduce, I need your help, thanks!

[rodrigobdz]

gem_make.out does not contain any additional information.

I'm also getting this error:

make: *** No rule to make target `/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0/universal-darwin18/ruby/config.h', needed by `adj_matrix.o'.  Stop.

I don't have a dir named universal-darwin18 there, I have universal-darwin17. Guessing that's an Apple issue with Mojave?

[KernelPanicAUS]

I've managed to overcome this issue with the following steps:

• Use chruby and ruby-install to install a clean version of ruby.
• Install the full xcode package and its cli tools.

Since then I've managed to install a whole bunch of gems with native extensions without any issues.

This leads me to suspect that the version of ruby shipped with Mojave is missing a bunch of C headers that make installing any gems with native extensions a massive pain in the rear.

It might be worth adding something to the Readme for Mojave users 🤔

The problem is that Apple can't decide whether to keep that include directory around…

• 10.11: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include exists.
• 10.12: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include does not exist.
• 10.13: ^ that directory ^ does exist.
• 10.14: ^ that directory ^ does not exist.

Strange.
