项目场景：
今天从GitHub上拉了一个vue前端项目，也就是人人开源的前端项目。在进行npm install的时候给我报了一大堆错误
D:\Spring-Cloud-Platform-UI-dev>npm install
npm ERR! code CERT_HAS_EXPIRED
npm ERR! errno CERT_HAS_EXPIRED
npm ERR! request to https://registry.npm.taobao.org/@types/semver failed, reason: certificate has expired
npm ERR! A complete log of this run can be found in:

一开始，清理缓存，去官网看一下node和npm的对应版本是否正确，以下是node官网上node和npm的对应版本。
官网地址：
https://nodejs.org/zh-cn/download/releases
对应版本：
试过了 如下办法
- 查看npm镜像设置
npm config get registry
- 将npm设置为淘宝镜像
npm config set registry https://registry.npm.taobao.org
- 再次查看npm镜像设置
npm config get registry
- 重新install
npm install
后面又找了一下别人的解决方法：
- 第一步：解决方法如下：
- 清除npm缓存
npm cache clean --force
- 更换npm镜像源：
npm config set registry https://mirrors.huaweicloud.com/repository/npm/
1、然后 运行 npm install 后报错如下：
gyp ERR! configure error
gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

最后 发现是 node-sass 安装源的问题，运行如下：
npm config set sass_binary_site=https://npm.taobao.org/mirrors/node-sass
2、然后 运行 npm install 后报错如下：
gyp ERR! configure error
gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

3、仔细看了控制台报错，最后发现是因为缺了node-sass 的包。
npm install node-sass
搞定，完结，撒花 ！
