gyp ERR! find Python You need to install the latest version of Python.
gyp ERR! find Python Node-gyp should be able to find and use Python. If not,
gyp ERR! find Python you can try one of the following options:
gyp ERR! find Python - Use the switch --python="C:\Path\To\python.exe"
gyp ERR! find Python (accepted by both node-gyp and npm)
gyp ERR! find Python - Set the environment variable PYTHON
gyp ERR! find Python - Set the npm configuration variable python:
gyp ERR! find Python npm config set python "C:\Path\To\python.exe"
gyp ERR! find Python For more information consult the documentation at:
gyp ERR! find Python https://github.com/nodejs/node-gyp#installation

解决方案：
1. 管理员权限打开cmd，在项目目录下执行：npm install --global --production windows-build-tools
安装成功会在C:\Users\**（电脑用户名） 目录下创建.windows-build-tools文件夹
2. 必须配置环境变量，将C:\Users\**\.windows-build-tools\python27地址添加到path中
3. 重启VSCode或者cmd窗口，我当时打开了2个VSCode窗口，只重启了一个，结果环境变量地址没有生效，又折腾了好久，一定要把所有VSCode窗口关闭重启。
也可以在python官网下载安装，还是要配置环境变量
在npm install安装期间，电脑又提示了安装.net framework4.8
