I am trying build a dev-env for my work-stations where i do not have access to the internet. I was hoping to install basic gem offline and transport it over to my work-station however while trying the below command:

```auto
gem install -i tmp logstash-devutils

```

I am getting below response

```auto
ERROR: Could not find a valid gem 'logstash-core' (= 5.1.2.snapshot1) in any repository
ERROR: Possible alternatives: logstash-core

```

PS: I have already installed `logstash-core`
