使用npm安装node-sass时，或者安装需要python2的依赖时，会报出以下错误。

复制代码解决方案一:
1. 安装python2
- 可以用npm命令安装
npm install -g node-gyp
复制代码- 也可以自行下载安装 Python 2.7
2. 安装完毕后配置环境变量
npm config set python python2.7
复制代码3.再配置一下版本
npm config set msvs_version 2017
复制代码修改完毕，之后就可以正常安装node-sass了，如果还不行就使用淘宝镜像。
解决方案二(推荐)
node-sass实在太坑了，之前遇到安装失败使用方法一完美解决。最近又一次遇到了，但是方法一又无效了。于是我又在网上找到另一个方法，就是用dart-sass来替换node-sass。
正常的替换也会出问题，还要改配置。使用以下方法便可以解决 yarn安装的:文章来源：https://www.toymoban.com/news/detail-538241.html
yarn add node-sass@yarn:dart-sass -D
复制代码npm安装的:文章来源地址https://www.toymoban.com/news/detail-538241.html
yarn add node-sass@npm:dart-sass -D到了这里，关于安装node-sass失败 或 npm install Error: not found: python2 解决方案的文章就介绍完了。如果您还想了解更多内容，请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章，希望大家以后多多支持TOY模板网！
