Description

**Describe the bug**
I can't install dependencies with Poetry.

**To Reproduce**
Steps to reproduce the behavior:
1. `poetry env use 3.9`
2. `poetry lock`
3. `poetry install`

**Screenshots**
Poetry reports that numpy is not installed before scipy, which is not true, because I have confirmed numpy is already installed.

```
• Installing scipy (1.6.1): Failed

ChefBuildError

Backend subprocess exited when trying to invoke build_wheel

Error: 'numpy' must be installed before running the build.

Note: This error originates from the build backend, and is likely not a problem with poetry but with scipy (1.6.1) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "scipy (==1.6.1)"'.
