Cause

gem net-http is defined as dependencies for multiple gems for network usages(like faraday, net-ssh, net-protocol). This happen to load the gem multiple times and causing the warnings. As suggested here I explicitly added gem to the Gemfile and issue is fixed.

gem 'net-http', '0.3.2' # explicit added to suppress warnings

You have already activated uri 0.10.0, but your Gemfile requires uri 0.12.0.

/opt/xx/Ruby/2.7.7/x64/lib/ruby/gems/2.7.0/gems/bundler-2.4.6/lib/bundler/runtime.rb:304:in `check_for_activated_spec!': You have already activated uri 0.10.0, but your Gemfile requires uri 0.12.0. Since uri is a default gem, you can either remove your dependency on it or try updating to a newer version of bundler that supports uri as a default gem. (Gem::LoadError)

Cause:

This is caused by collision of two version of gems installed in your machine. (CI in my case).

Fix

To Fix it, I had to specify the uri gem version to 0.10.0 which was default in my machine.

gem 'net-http', '0.3.2' # explicit added to suppress warnings
gem 'uri', '0.10.0'
