test-your-own-ruby-gem-locally

Sometimes you need to do the upgrade to the gem and do test in local. Here is the easiest way to apply the latest gem version to your irb.

• cd to the root dir of your gem project
• rake build
• gem build GEMNAME.gemspec( like gem build to_file.gemspec )
• sudo gem install GEMNAME -l ( like sudo gem install to_file -l )
• run irb and do your test 🕶️
