Create the virtualenv inside the project's root directory.
If not set explicitly, `poetry` by default will create virtual environment under
`{cache-dir}/virtualenvs` or use the `{project-dir}/.venv` directory when one is available.
If not set explicitly, `poetry` by default will create a virtual environment under
`{cache-dir}/virtualenvs` or use the `{project-dir}/.venv` directory if one already exists.
If set to `true`, the virtualenv will be created and expected in a folder named
`.venv` within the root directory of the project.
{{% note %}}
If a virtual environment has already been created for the project under `{cache-dir}/virtualenvs`, setting this variable to `true` will not cause `poetry` to create or use a local virtual environment.
In order for this setting to take effect for a project already in that state, you must delete the virtual environment folder located in `{cache-dir}/virtualenvs`.
You can find out where the current project's virtual environment (if there is one) is stored
with the command `poetry env info --path`.
{{% /note %}}
If set to `false`, `poetry` will ignore any existing `.venv` directory.
