Isn’t this what got discussed in: [Development, Test, and Production Environments](https://discourse.julialang.org/t/development-test-and-production-environments/1974)?

with it you can do something like this for REQUIRE:

```julia
gem 'httparty'

group :development, :test do
  gem 'better_errors'
end

group :production do
  gem 'postgres'
end

```

// edit: i just used a gemfile instead of a require file because i had one on hand
