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

Question

我在 Poetry pyproject.toml 文件中有一个 Numpy 作为依赖，但它安装失败。

macOS 大苏尔
Python 3.9 通过 Homebrew 安装

如何解决？

如果我用 pip 安装 Numpy，它安装得很好。

Answer 1

确保从 Homebrew 安装了 OpenBLAS：

brew install openblas

然后在运行任何安装脚本之前，确保你告诉你的 shell 环境使用 Homebrew OpenBLAS 安装

export OPENBLAS="$(brew --prefix openblas)" 
poetry install

如果出现错误

                File "/private/var/folders/tx/50wn88yd40v2_6_7fvfr98z00000gn/T/pip-build-env-uq7qd2ba/overlay/lib/python3.9/site-packages/wheel/bdist_wheel.py", line 252, in get_tag
                  plat_name = get_platform(self.bdist_dir)
                File "/private/var/folders/tx/50wn88yd40v2_6_7fvfr98z00000gn/T/pip-build-env-uq7qd2ba/overlay/lib/python3.9/site-packages/wheel/bdist_wheel.py", line 48, in get_platform
                  result = calculate_macosx_platform_tag(archive_root, result)
                File "/private/var/folders/tx/50wn88yd40v2_6_7fvfr98z00000gn/T/pip-build-env-uq7qd2ba/overlay/lib/python3.9/site-packages/wheel/macosx_libfile.py", line 356, in calculate_macosx_platform_tag
                  assert len(base_version) == 2
              AssertionError

这应该已经在最近的 Python 打包工具中修复了。

确保

诗是最近的版本
Numpy 是足够新的版本
任何使用 Numpy 的依赖项，如 Scipy 或 Pyarrrow 也是最新版本

例如在你的 pyproject.toml

[tool.poetry.dependencies]
# For Scipy compatibility
python = ">=3.9,<3.11"

scipy = "^1.8.0"
pyarrow = "^7.0.0"

即使这仍然失败，您可以尝试在 Poetry virtualenv 中运行宁 poetry install 之前用 pip 预安装 scipy （输入 poetry shell）这应该选择预编译的 scipy 轮。当存在预编译轮时，Poetry 不应尝试再次安装它然后在构建步骤中失败。

poetry shell
pip install scipy

此后运行诗歌正常：

poetry install
