npm install 出错及其debug办法

执行npm install下载依赖报错:

npm ERR! Unexpected end of JSON input while parsing near '...,"dist":{"shasum":".....'

npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\admin\AppData\Roaming\npm-cache_logs\2019-08-03T06_21_13_023Z-debug.log

解决办法：win+r 输入cmd 执行npm cache clean --force命令
提示: npm WARN using --force I sure hope you know what you are doing.说明操作成功.

其它并行动作：换一下网络。

再次执行npm install,下载依赖成功,问题解决.感谢两位大佬经验,附上博文连接:
