ruby 在任何ruby（bundle）控制台上使用任何gem

Posted 2021-05-15

# Install the gem
system 'gem install <gemname> -v <version>'

# Require its load path (depends on the gem file tree)
$LOAD_PATH << "#{`gem env gemdir`.strip}/gems/<gemname-version>/lib"

# Require the gem file
require '<gemname>'


# For example:
system 'gem install differ -v 0.1.2'
$LOAD_PATH << "#{`gem env gemdir`.strip}/gems/differ-0.1.2/lib"
require 'differ'
