Issue

I'm wondering why it takes 13-30 seconds to install my package (on two different machines).
This occurs when the package and it's dependencies are already installed.
`$ time poetry install -vvv
Using virtualenv: /Users/apayne/Envs/smithers
Installing dependencies from lock file

Nothing to install or update

Smithers is the name of the package I'm installing with poetry. The installing smithers step takes the majority of the time. Is poetry doing anything but creating a symlink? I don't understand why this should take so long. If the package is already installed in editable mode, why does poetry try installing it again?

Much thanks!
