无法在 Ubuntu Focal (Python 3.8.10) 中从源代码安装 Scipy（找不到 `./scipy/_lib/highs/CMakeLists.txt`）

Question

我目前正在尝试从源代码安装 SciPy，但我一直遇到问题。 我正在按照https://scipy.github.io/devdocs/building/linux.html上的说明进行操作。

我做了什么：

1. 克隆了 github 仓库。
2. 使用sudo apt-get install gcc g++ gfortran python3-dev libopenblas-dev liblapack-dev下载依赖项。

什么不起作用：

python3 setup.py build和python3 setup.py install都不起作用，有或没有sudo 。 此外，通过键入 pip3 install 尝试使用pip安装它pip3 install. 也不起作用。

该问题似乎与无法找到名为./scipy/_lib/highs/CMakeLists.txt的文件有关。 这个文件应该是自动生成的吗？

pip3 install. :

Answer 1

正如您在 git上看到的那样，文件夹highs包含在那里，但作为一个子模块，您在克隆 repo 时可能没有下载它。

Go 到 repo 主目录并运行

git submodule init
git submodule update

然后确认指定的文件夹存在并被填充
