Rails Bundler Doesn't Install Gems Inside a Group

Rails bundler doesn't install gems inside a group

Within a term session, it remembers the without option. If you first ran

bundle install --without development 

it remembers that you did this and will automatically repeat this for the next

bundle install #remembers and includes --without development

running something else, like bundle install --without nothing should clear the cache. Am I right?

update 20150214: This is fixed in bundler 2.0, according to issue referenced in comment by @Stan Bondi (https://github.com/bundler/bundler/issues/2862). Thanks Stan.

Bundler - updating gems in a particular group

Yes, with

$ bundle update --conservative --group test development

Bundler’s --conservative option is key, because it prevents updates in any "Production" gem that is also a dependency of a "Test" or "Development" gem.

bundler incorrectly trying to install development and test group gems in production

After a lot of digging I found the fix for this issue. All I had to do was run bundle install --without development test before starting the server. This adds a .bundle/config file in the rails root with the line BUNDLE_WITHOUT: test:development . Now whenever you run bundle install or start the server it'll ignore those groups.

From the documentation

The Bundler CLI allows you to specify
a list of groups whose gems bundle
install should not install with the
--without option. To specify multiple groups to ignore, specify a list of
groups separated by spaces.

bundle install --without test bundle
install --without development test
After running bundle install --without
test, bundler will remember that you
excluded the test group in the last
installation. The next time you run
bundle install, without any --without
option, bundler will recall it.

Also, calling Bundler.setup with no
parameters, or calling require
"bundler/setup" will setup all groups
except for the ones you excluded via
--without (since they are obviously not available).

Groups of gems in Bundler

You just need to specify the option. See this too (it saves the option so you only have to specify it once)

bundle install --without production
