安装 scipy 时找不到库 mkl_rt、openblas、lapack - 如何更改库的标志

Question

我是 python 和 pip 生态系统的新手。我正在尝试安装 scikit-image 并且我想它正在安装 scipy 作为依赖项。我正在使用 macOS 11.1，并且我知道对该版本的支持不是很好，因为它刚刚发布，但我能够通过更改几个标志（LDFLAGS、CPPFLAGS）来安装 numpy、pillow 等软件包。

谁能告诉我是否可以通过更改一些配置来解决以下安装错误？

我已经安装了 openblas、mkl_rt 库。

(trial) ~/.virtualenvs/trial python -m pip install scikit-image

我在使用通过 pyenv 安装的 Python 时遇到了同样的问题。 它缺少一些依赖项或路径未成功添加。

因此，要么您需要下载所有依赖项并将它们添加到您的 .profile 文件（bash 或 zsh）中，这些文件未使用以下命令安装：

pyenv install (version)

或者，您可以尝试通过 HomeBrew 安装，它会下载所有依赖项/库并将它们添加到使用以下命令成功运行 python 程序所需的默认路径：

brew install python

这是一个不错的链接，您可以按照该链接获取详细说明：https://docs.python-guide.org/starting/install3/osx/

然后我注意到您正在使用虚拟环境。我建议在全新安装完成后创建一个新的虚拟环境。 （我知道这很明显）；）

希望这能解决您缺少库的问题。
