Bundler loads unnecessary environments within Overmind.

[shetty-tejas]

Problem Description and Reproduction Steps

This is a part of my Gemfile. Some of the gems like VCR, WebMock and Mocha are specifically meant to be running while the 'test' environment is loaded.

While running something like rails c, I can see that WebMock or any gems specifically meant to be running for 'test' environment are not present.

However, If I run the same command while using Overmind or Foreman, the gems meant for 'test' environment are loaded as well.

A workaround that I could find to avoid this is running bundle lock before specifically running any command that uses bundle.

Did you try upgrading rubygems & bundler?

Yes.

I can't seem to reproduce. I think this is a environment specific problem and not a bundler issue, which may be be a bit tricky for us to help diagnose. Maybe there is a overmind configuration that somehow requires those gems (not very familiar with overmind)? I'd recommend adding a puts caller_locations inside one of those gems, this will allow to see what code is requiring those files
