Ignoring ffi-1.9.13 because its extensions are not built

• Version: Logstash 2.3.4 from Elastic repository

I got the following warning message when installing translate (which installs just fine): "Ignoring ffi-1.9.13 because its extensions are not built. Try: gem pristine ffi --version 1.9.13"

I'm having the same issue installing translate.

When I try gem pristine ffi --version 1.9.13 I get ERROR: While executing gem ... (Gem::Exception) Failed to find gems ["ffi"] = 1.9.13

Is there another way to get the translate plugin working on version 2.3.4?

• version 2.3.4 from deb repo
• Ubuntu 16.04

Same here! Following message while trying to install any plug-in on 2.3.4:

An error occurred while installing ffi (1.9.14), and Bundler cannot continue. Make sure that gem install ffi -v '1.9.14' succeeds before bundling.

Any news for this?
