npm安装带来了很多错误。

Question

我在我新买的笔记本电脑上安装了windows 11，安装了Nodejs，角Cli，但是当我在我的项目中运行npm安装时，一切都出现了错误，我尝试了很多，但无法解决。

升级降级节点。更新所有节点包。清除缓存等。

注意：

node version: v16.13.0
npm version: 8.1.4
angular cli version: Angular CLI: 10.1.7

所有这些都试过了，但解决不了。

一步一步地帮助我。

Answer 1

这与node.js和package.json中的节点-sass之间的版本不匹配有关。您可以在这里检查所有支持的版本。https://github.com/sass/node-sass

您要么需要更改node.js或node.js版本，然后再进行npm安装。

Answer 2

npm还有多清楚？！

错误:未找到: c:\python27\python.exe

有些包需要python2.7；另一些则需要python，并将接受Python 3。这很痛苦，特别是对于那些不使用Python的人。但是您的问题是基本问题-安装Python，然后再试一次。
