Issue

I am using docker to build a containerised application. Inside the container, I install poetry as root, whilst I perform the installation of my package as a non-root user. This fails after trying to write to the system site-packages directory. I have disabled virtualenvs for my use case.

This error was introduced between 1.0.10 and the RC release, and I think it likely that the recent change to editable installs was the culprit.
