Logstash 5.2.0 logstash-plugin install produces GemfileNotFound error when run outside of Logstash home directory

[OmarDarwish]

Attempting to run log-stash-plugin install <url> for a .zip file fails if run outside of Logstash install directory:

If run from inside Logstash's install directory, it works as expected:
