在 VS 代码上安装 numpy 时出现“准备元数据 (pyproject.toml) ... 错误”（Fantasy Football Data Pros：Data Munging with Pandas）

Question

所以我试图在 VS Code 上安装 numpy 1.20.3，当它显示：

我是这样安装的：

\n

(venv) PS C:\\Users_\\OneDrive\\Desktop\\VOR-Models\\2021-VOR-Model> pip install -r requests.txt

\n

因为我很迷茫，所以我给你看requirements.txt。这个函数实际上安装了 numpy 之前的所有内容，然后失败了。

\n

clearbeautifulsoup4==4.9.3\ncertifi==2021.5.30\nchardet==4.0.0\nidna==2.10\nnumpy==1.20.3\npandas==1.2.4\npython-dateutil==2.8.1\npytz==2021.1\nrequests==2.25.1\nsix==1.16.0\nsoupsieve==2.2.1\nurllib3==1.26.5\n

\n

任何帮助表示赞赏。我这样做的原因是因为我参加了在线课程（https://www.fantasyfootballdatapros.com/），并且正在尝试用 pandas 进行数据处理。为此我需要 NumPy。我也尝试查看其他问题，但他们没有给我我需要的答案，或者根本没有答案。请帮忙。

Answer 1

它在错误消息中说了这一点。

RuntimeWarning：NumPy 1.20.3 可能尚不支持 Python 3.10。

两次快速尝试：

1. 在不查看每个包的情况下，尝试从需求中删除 numpy，然后再次运行“python -m pip install -rrequirements.txt”。然后在命令行中，尝试输入此命令以查看它是否因为其他软件包而安装（例如 Tensorflow 自动安装 numpy，以及它所依赖的版本）。

蟒蛇-m numpy

2. 尝试较低的 numpy 版本。在requirements.txt中尝试输入1.20.3以下的内容

numpy==1.19.2
