Issue

From time to time I clean out the installed packages by running "pip freeze | xargs pip uninstall -y" to make sure I have the necessary packages added to pyproject.toml file via poetry. When I run poetry install, it will install all the dependencies but it also creates a .egg-info and installs my project into the site-packages. I then have to run pip uninstall project-name to uninstall my current project.

This doesn't seem correct since i'm not creating a build. If I run poetry update, only the dependencies are installed, but all package versions are also updated.

Running poetry install should only install the project dependencies, not install the current project into the site packages.

I have run poetry self:update and it will only update to version 0.12.17 and will not update to 1.0.0b1
