# 捉虫
既然是 npm 的问题,那首先去 github 的源码中找找问题
npm 的源码在 https://github.com/npm/cli (opens new window),找到以下 Issue
# 解决方案
这是因为本地 npm cache
的问题,清除掉本地的 cache 即可成功,如下所示
$ npm cache clean --force
npm WARN using --force I sure hope you know what you are doing.
$ npm i -g serverless
另外可以通过 npm cache verify
去查看缓存位置
$ npm cache verify
