ERROR: Failed to build ‘airsim’ when getting requirements to build wheel

一、现代pip的默认行为

当存在pyproject.toml时：

pip → 创建临时隔离环境 → 安装 build-system.requires → 执行构建

但是这个临时环境不会集成当前环境的numpy

二、AirSim的问题

在AirSim的setup.py中：

import numpy as np

但是：

• 他没有在pyproject.toml的build-system.requires中声明numpy
• numpy只在install_requires中

install_requires是运行时依赖，而build-system.requires是构建时依赖

因此在构建airsim的时候，会识别不到numpy

这里猜测是AirSim的版本较旧，文件中根本没有pyproject.toml

三、修改方法

采用--no-build-isolation

不在构建临时环境，而是直接在当前的环境构建，而当前环境已经有numpy，所以成功

pip install airsim --no-build-isolation
