但是当我构建另一个使用 Angular 12 的项目时，我没有遇到同样的错误。这很重要，还是我错过了没有它就无法构建的东西？有人可以指导我解决它吗？

【问题讨论】：

你的代码是为 Python 2 设置的，但你只有 Python 3
我已经安装了 Python 2.7.17 但没有发现任何效果。我可以有更多的方法来解决它吗？
尝试将 Node 版本降级到 14.X
将python2 放入您的路径
@sojin 你的想法对我有用！谢谢！

标签： node.js npm npm-install

【解决方案1】：

我也有这个问题，我做了什么：

1- npm 卸载 node-sass

2- npm i -D sass

3- npm i

【讨论】：

【解决方案2】：

这通常是因为您的环境在运行 npm install 后发生了变化。运行 npm rebuild node-sass 下载当前环境的绑定。”

所以我运行npm rebuild node-sass 并且成功了！然后 npm install 一切正常。
