我正在尝试在 Mac 上使用 Poetry v1.7.1 构建一个虚拟环境，通过
poetry install[tool.poetry]
...
[tool.poetry.dependencies]
python = "^3.9"
mlrun = "1.4.1"
torch = "1.13.1"
transformers = "4.20"
sentence-transformers = "2.2.2"
scikit-learn = "1.2.2"
tensorboard = "2.12.2"
tqdm = "4.65.0"
attr = "0.3.2"
attrs = "23.1.0"
cattrs = "23.2.3"
ruamel-yaml-clib = "0.2.2"
ruamel-yaml = "0.16.10"
emoji = "2.4.0"
s3fs = "2023.1.0"
[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"
但是，我总是收到此错误：
Package operations: 38 installs, 2 updates, 0 removals

Note: This error originates from the build backend, and is likely not a problem with poetry but with pyyaml (5.4.1) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "pyyaml (==5.4.1)"'.
按照这个线程，我尝试将此行添加到 toml 文件中，但收到错误：
The Poetry configuration is invalid:
- data.dependencies.PyYAML must be valid exactly by one definition (0 matches found)
我还尝试升级PIP，并通过在toml文件中添加
pyyaml = "6.0.1"我也想尝试这种方式：https://github.com/yaml/pyyaml/issues/736，但似乎无法在pyproject.toml中设置环境变量......有人可以帮忙吗？谢谢
事实证明，您可以下载wheel文件并将其放在工作目录中，并在toml文件中指定文件名：
pyyaml = {file = "PyYAML-5.4.1-cp39-cp39-macosx_10_9_x86_64.whl"}这现在允许我成功安装 PyYaml。
