Answer 1

下载并安装 python2。 Python310 将不起作用，因为它们的要求略有不同（例如带括号的 print: print() ）

Answer 2

node-gyp 正在寻找一个 python 工作安装，但在您的 OS.

的 PATH 变量中找不到它

node-gyp 需要安装 python 才能使用。 来自node-gyp-3.8.0

的版本文档

• 您必须安装 Python 2.7
• 您需要安装Windows构建工具

作为附加依赖项。如果你已经安装了python-2.7，你可以使用以下任一命令配置gyp

node-gyp --python /path/to/python2.7

或

npm config set python /path/to/executable/python2.7
