--binstubs: Generate bin stubs for bundled gems to ./bin
--clean: Run bundle clean automatically after install
--deployment: Install using defaults tuned for deployment environments
--frozen: Do not allow the Gemfile.lock to be updated after this install
--full-index: Use the rubygems modern index instead of the API endpoint
--gemfile: Use the specified gemfile instead of Gemfile
--local: Do not attempt to fetch gems remotely and use the gem cache instead
--no-cache: Don't update the existing gem cache.
--no-prune: Don't remove stale gems from the cache.
--path: Specify a different path than the system default ($BUNDLE_PATH or $GEM_HOME). Bundler will remember this value for future installs on this machine
--quiet: Only output warnings and errors.
--shebang: Specify a different shebang executable name than the default (usually 'ruby')
--standalone: Make a bundle that can work without the Bundler runtime
--system: Install to the system location ($BUNDLE_PATH or $GEM_HOME) even if the bundle was previously installed somewhere else for this application
--without: Exclude gems that are part of the specified named group.
--jobs: Install gems using parallel workers.
--retry: Retry network and git requests that have failed.
Gems will be installed to your default system location for gems. If your system gems are stored in a root-owned location (such as in Mac OSX), bundle will ask for your root password to install them there.
While installing gems, Bundler will check
vendor/cache and then
your system's gems. If a gem isn't cached or installed, Bundler will try to
install it from the sources you have declared in your Gemfile.
--system option is the default. Pass it to switch back after
--path option as described below.
