在Ubuntu 21.10上，实际上没有安装Python2.x，当我在一个大项目上执行“npm install”时，我遇到了以下错误（package.json很大，但这两行可能是相关的：

...
  "devDependencies": {
    ...
    "sass": "^1.46.0",
    "sass-loader": "10.1.1",
...

）

$ npm install

特别是，这一行不是有效的Python3.x synthax：import sys; print "%s.%s.%s" % sys.version_info[:3];，所以即使 * 伪造 * 一个名为'python'或'python 2'的符号链接，它指向系统上的-〉'/usr/bin/python3.9'，自然也没有帮助。
npm cache clean --force也没有帮助。
系统信息：

$ npm --version

$ node --version

$ uname -mor

关于我可以做些什么来修复这个错误有什么提示吗？
