可以尝试以下几种方法:

1. 升级node-sass到最新版本,新版本移除了对python 2的依赖。

npm uninstall node-sass
npm install node-sass

2. 如果必须使用旧版本node-sass,可以单独安装python 2,并确保将其路径添加到PATH环境变量中。

3. 在安装node-sass时指定python 2的路径:

npm install node-sass --python=python2

4. 使用node-gyp自定义编译参数,跳过执行python脚本:

npm install --node-gyp-norequire

总体来说,建议尽可能升级到最新版本的node-sass,这样可以避免与python 2的兼容问题。

如果必须使用旧版本,可以尝试指定python 2的路径或者自定义编译参数。
