使用 pip install 并行构建 C Python 模块

Question

我想加快这个Python C 模块的安装阶段。setuptools 可以使用多个内核构建扩展：

python setup.py build --parallel 8

现在我如何告诉pip installsetuptools 并行构建模块？

pip install没有--build-option或失败pip install --install-option并--global-option显示此错误消息：

$ python -m pip install --build-option='--parallel 8' .
