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%2fsemver failed, reason: certificate has expired

npm ERR! A complete log of this run can be found in:

pm-cache_logs?4-07-26T01_13_03_869Z-debug.log

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

1. 查看npm镜像设置

   npm config get registry

2. 将npm设置为淘宝镜像

   npm config set registry https://registry.npm.taobao.org

3. 再次查看npm镜像设置

   npm config get registry

4. 重新install

   npm install

后面又找了一下别人的解决方法：

1. 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

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 ！
