bundler install RAILS_ENV=test installs all gems again?

I was trying to install just my test gems and suddenly bundler tried to install ALL gems again. Why is this so? shouldn't it be looking at the same gemset as my dev?

bundle install RAILS_ENV=test

TROLOLOL!

apparently bundler install <something> will install all your gems in that folder. I just found out when I saw an uncommitted folder named "RAILS_ENV=test/" when I did git status.

As an added note, it "remembers" the old path so any subsequent bundle installs created that RAILS_ENV=test/ folder again. To reset it, use:

bundler install --system

The command you're looking for is

bundle install --system

Tested on Bundler version 1.0.10
