前端install出错npm ERR! network request to registry.npmjs.org。。 failed, connect ETIMEDOUT

npm install、vue、idea

背景

小长假复工，处理不同项目切换前后端代码，npm install卡半天，最后失败

问题描述

切换代码后，idea提示重新install，点击其按钮后，依赖安装进度安装了一阵卡住不动了，控制台最后爆出错误如下：

原因分析

控制台的日志还提示看某日志文件，然而其内没有找到有价值信息。

咨询ai助手，却告诉我检查网络，配置代理，这可是公司电脑，胡说啥呢？

bing搜索：npm ERR! network request to https://registry.npmjs.org/jspdf/-/jspdf-2.5.2.tgz failed, reason: connect ETIMEDOUT 104.16.27.34:443
找到这篇博客，其中提到切换镜像地址，
但其地址已失效，好在评论区有人给出了可用地址

解决方案

1. 命令行进入前端项目目录，或在项目目录打开命令行
2. 查看镜像地址npm config get registry，https://registry.npmjs.org/
3. 切换地址npm config set registry https://registry.npmmirror.com
4. 重新查看镜像地址npm config get registry，https://registry.npmmirror.com/
5. 重试install，成功！
