> dependency pathing is a pain in most other languages This has been a solved problem in the Ruby community for nearly a decade thanks to bundler. When I first started writing Ruby it had all the same problems as other languages, there were various attempts to solve it (similar to virtualenvs) but nothing really worked properly. Then bundler came along, and even from early releases it had pretty much figured it out. The way it works is by having a human generated manifest file with a list of libraries you think you need (Gemfile) and the tool will then fetch those libraries (they can be installed in a vendor directory or globally for the specific Ruby version). You don't need to specify versions or deps (but can if required), as when the tool runs it will generate another manifest file (Gemfile.lock) which lists the versions of all libraries and their dependencies. Both files should be committed, so when you coworker checks out the project they know they have the exact same versions as you. There's another command to list outdated libraries, and to upgrade all or a specific library later. The tooling checks the versions of libraries on every execution (unlike npm or yarn) and spits out an error if your local versions don't match the manifest. It automatically creates wrappers around binaries so you don't need to prefix commands from other tooling. There's built in support for installation in a deployment environment, so you don't install testing libraries there. Together with tools like rvm/rbenv, it makes managing multiple Ruby versions and multiple projects, just work. https://www.cloudcity.io/blog/2015/07/10/how-bundler-works-a-history-of-ruby-dependency-management/ https://www.cloudcity.io/blog/2015/07/10/how-bundler-works-a...
