Installation log

Bundler and RubyGems.org are free for anyone to use, but maintaining them costs more than $25,000 USD every month. Help us cover those costs so that we can keep the gem ecosystem free for everyone: https://ruby.to/support-bundler</pre>

NOTE : gem server : `​https://rubygems.org` by default

If some of your gems need to be fetched from a private gem server, this default source can be overridden for those gems.

After installing any needed gems to your system, bundler writes a snapshot of all of the gems and versions that it installed to Gemfile.lock.
