Gem install ffi Failed to build gem native extension - ruby-on-rails

Question

I'm having troubles to do bundle install in one project I get to work on in Rails 4.2.10. When I bundle I receive the next error:
An error occurred while installing ffi (1.9.25), and Bundler cannot continue.
Make sure that gem install ffi -v '1.9.25' succeeds before bundling.
In Gemfile:
s3_direct_upload was resolved to 0.1.6, which depends on
sass-rails was resolved to 5.0.7, which depends on
sass was resolved to 3.6.0, which depends on
sass-listen was resolved to 4.0.0, which depends on
rb-inotify was resolved to 0.9.10, which depends on
ffi
When I run gem install ffi -v '1.9.25' also an error occurs:
Building native extensions. This could take a while...

I've been trying many solutions online but cannot resolve this issue.
Seems the issue is with my system as I'm new to the team and the other developers were unable to help me as they do not have this kind of issue.

Answer 1

I was able to successfully install ffi with the following command:
LDFLAGS="-L/usr/local/opt/libffi/lib" PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig" gem install ffi -v '1.9.25'

Answer 2

According to the libffi README, only GCC is a tested compiler on macOS. You are using Clang, which doesn't support the command line option -print-multi-os-directory.
You need to either patch libffi to work with Clang, or use GCC.

Answer 3

Your error is the following Configuring libffi
clang: error: unsupported option '-print-multi-os-directory'
clang: error: no input files because Clang (wich is the C compiler you are using) doesn't support the option '-print-multi-os-directory'.
Could you check that X-Code command line tools are perfectly installed by executing the following command? xcode-select --install
Also would you mind to try brew install automake autoconf libtool libffi to install required dependencies?
