报错信息

npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated tar@2.2.2: This version of tar is no longer supported, and will not receive security updates. Please upgrade asap.
npm WARN deprecated core-js@2.6.12: core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js.

升级Node

https://nodejs.org/en/download/

在这里插入图片描述
下载最新版本解压覆盖之前的版本

忘记之前在哪个位置可通过 where node

安装cnpm

1、安装cnpm，输入以下命令：

npm install -g cnpm --registry=http://registry.npm.taobao.org

注意：为了避免每次安装都需要–registry参数，可以使用如下命令

进行永久设置：npm config set registry http://registry.npm.taobao.org

重新安装node-sass

根据报错信息得出是node-sass的版本问题
更新 node-sass

node-sass和node的版本对照： https://www.npmjs.com/package/node-sass

后续参考：
https://blog.csdn.net/qq_37974755/article/details/124604371?utm_medium=distribute.pc_relevant.none-task-blog-2_defaultbaidujs_baidulandingword~default-4-124604371-blog-133519851.235^v39pc_relevant_default_base&spm=1001.2101.3001.4242.3&utm_relevant_index=7

或者

如果node是最新版本，则可以直接使用以下命令安装即可
npm install sass-loader node-sass --save-devcnpm install sass-loader node-sass --save-dev如果node不是最新版本，则需要安装对应的版本号才行
npm install sass-loader@版本号 node-sass@版本号 --save-dev //安装对应的版本cnpm install sass-loader@版本号 node-sass@版本号 --save-dev //安装对应的版本

卸载安装低版本Node

npm install –save-dev node-sass – force

https://www.iotword.com/16158.html

卸载python

根据报错信息

npm ERR! gyp verb `which` failed  python2 Error: not found: python2

可以执行以下命令试试
npm install node-sass --python=python2.7 --force

由于我本机python环境是3.8.4
一直报错找不到python2 索性卸载了 python
