在 M1 和 macOS 上使用 Poetry 安装时 Numpy 安装失败

Question

我有一个 Numpy 作为 Poetrypyproject.toml文件中的依赖项，但安装失败。

          note: This error originates from a subprocess, and is likely not a problem with pip.

• macOS 大苏尔
• 通过 Homebrew 安装 Python 3.9

怎么解决呢？

如果我用 pip 安装 Numpy 它安装得很好。

Answer 1

确保您已从 Homebrew 安装了 OpenBLAS：

\n

brew install openblas\n

\n

然后，在运行任何安装脚本之前，请确保告诉您的 shell 环境使用 Homebrew OpenBLAS 安装

\n

brew install openblas\n

\n

如果出现错误

这个问题应该已经在最近足够多的 Python 打包工具中得到修复。

\n

确保

\n

\n
• 诗是最近的版本
\n
• Numpy 是足够新的版本
\n
• 任何使用 Numpy 的依赖项，例如 Scipy 或 Pyarrow 也是最新版本
\n

\n

例如在你的pyproject.toml

\n

[tool.poetry.dependencies]\n# For Scipy compatibility\npython = ">=3.9,<3.11"\n\nscipy = "^1.8.0"\npyarrow = "^7.0.0"\n

\n

即使这仍然失败，您也可以尝试在 Poetry virtualenv 中运行之前scipy预安装（输入） 这应该会拾取预编译的 scipy 轮子。当预编译轮存在时，Poetry 不应尝试再次安装它，然后导致构建步骤失败。pippoetry installpoetry shell

\n

export OPENBLAS="$(brew --prefix openblas)" \npoetry install\n

poetry install\n
