I am writing a filter plugin for Logstash and I'm following [this guide](https://www.elastic.co/guide/en/logstash/current/_how_to_write_a_logstash_filter_plugin.html).

So, I have finished the code, written everything and done some testing with rspec. Now, I have built the gem with `gem build logstash-filter-e164.gemspec` and sent it to the server where we run Logstash.

But, now running `bin/logstash-plugin install logstash-filter-e164-0.2.0.gem`, I get the following error:

```auto
Validating /tmp/logstash-filter-e164-0.2.0.gem
Installing logstash-filter-e164
ERROR: Installation Aborted, message: undefined method `[]=' for #<Bundler::Settings:0x28e94c2>
Did you mean? []

```

I have no idea what to do here, because it seems to be something from Bundler. I am using jruby-9.2.6.0.

Regards
