Dependency resolver
Poetry comes with an exhaustive dependency resolver, which will always find a solution if it exists.
And get a detailed explanation if no solution exists.
Isolation
Poetry either uses your configured virtualenvs or creates its own to always be isolated from your system.
The behavior is configurable.
Intuitive CLI
Poetry's commands are intuitive and easy to use, with sensible defaults while still being configurable.
It's also extensible with plugin system.
