npm 安装依赖报错解决：npm ERR! Unexpected end of JSON input while parsing near

问题概述

公司里的Jenkins构建某个前端项目一直报错，查看日志发现是在 npm i 阶段，错误如下：

npm WARN deprecated core-js@2.6.11: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.
npm WARN deprecated popper.js@1.16.1: You can find the new Popper v2 at @popperjs/core, this package is dedicated to the legacy v1
npm ERR! Unexpected end of JSON input while parsing near '...RZ9vRZCK58maAT55SsyLT'
 
npm ERR! A complete log of this run can be found in:
npm ERR!     /data/npm/node_cache/_logs/2020-06-22T09_56_13_966Z-debug.log

而在本地，或者其他机器上安装都是正常的，说明代码没问题，最后怀疑是npm的缓存，查询命令解决了问题

解救之法

清空npm的暂存

npm cache clean --force
