When installing Ruby with Rbenv in M1 Mac, it throws Build Failed error with message Inspect or clean up the working tree error... Let's look at how we can resolve the error and install the Ruby with Rbenv in our M1 Mac.

Error Message

Let's reproduce the error first:

  1. Install ruby with rbenv

    
      $ rbenv install 2.7.2
    
    
  2. Install error

    You will get the following error message

  - BUILD FAILED (macOS 11.2.3 using ruby-build 20210309)
  - Inspect or clean up the working tree at `/var/folders/.....`
Enter fullscreen mode Exit fullscreen mode

Ruby installation error message

NOTE: In my M1 Mac, I tried installing various ruby versions with rbenv like 2.5.0, 2.6.0, 2.7.0, 2.7.1, 2.7.2 and always ran into this same issue.

Fix

Instead of running the normal ruby install command with rbenv, let's prepend it with RUBY_CFLAGS="-Wno-error=implicit-function-declaration", which will supress all error and warnings and let the ruby installation complete.

$ RUBY_CFLAGS="-Wno-error=implicit-function-declaration" rbenv install 2.5.0
Enter fullscreen mode Exit fullscreen mode

Conclusion

Tada! See the magic? Ruby should install without any issue now.
