#### Installing unsafe dependencies
There are several packages that cannot be installed from the lockfile because they are
excluded by Poetry itself. As a result these packages cannot be installed by this plugin
either as test environment dependencies passed directly to `locked_deps` or as a transient
dependency. When one of these packages is encountered by the plugin a warning will be
logged to the console and
**the unsafe package will not be installed to the test environment**.
This list can be found in the Poetry source code
[here](https://github.com/python-poetry/poetry/blob/master/poetry/puzzle/provider.py). As
of [Poetry 1.1.6](https://github.com/python-poetry/poetry/releases/tag/1.1.6) there are
four packages classified as "unsafe" by Poetry and excluded from the lockfile:
- `setuptools`
- `distribute`
- `pip`
- `wheel`
#### Using with an unmanaged Poetry installation
In CI/CD systems, automation environments, or other Python environments where the loaded
site packages are not managed by Poetry, it can be useful to manage the local installation
of Poetry externally. This also helps to avoid problems that can be caused by the
`--no-root`, `--no-dev`, or `--remove-untracked` arguments to the `poetry install` command
which, in some situations, can cause Poetry to uninstall itself if Poetry is specified as
a dependency of one of the packages it is managing (like this plugin). To support these
use cases, this plugin specifies the `poetry` package as an optional dependency that can
be installed using a setuptools extra also named `poetry`.
