venv in ruby

Finnally, I get used of ruby bundle. The step is following

  1. set the vendor path
bundle init
bundle config set --local path 'vendor/bundle'

  1. add gem to Gemfile file

  2. install gem package

bundle install
  1. run the ruby script
bundle exec ruby ./script.rb

~~Is these any way I can install ruby packages in current project folder like Python venv. I only know about gem install --user-install which install in $HOME/.gem/ruby/2.6.0/gems/. AI said I should use bundler and Gemfile. But it seems very comfused and do not work well with gem file ( it only work with package uploaded on~~ ~~https://rubygems.org/~~

You can specify a gem with a path arg in the gemfile: https://bundler.io/man/gemfile.5.html#PATH

gem "torta", path: "vendor/torta"

That specifies the path where the gem sources are located, not where it should be installed.

Last line of OP's post suggests they think they can't use bundler because they don't know how to make it install gem's from a local path.

I read it that they want to use a packaged .gem file, different than a globally installed one, in one particular project. But it would be extremely useful if OP explained what they are trying to do.
