NPM过时抛出NPM错误！尚未实施

自从我更新到npm 6.9.0（节点8.12.0）后，我在运行

npm过时时遇到了这个错误：

$ npm outdated
npm ERR! Not implemented yet

当我在一个特定的包上运行
npm-outleted
时，例如
eslint
我得到了正确的输出：

$ npm outdated eslint
Package  Current  Wanted  Latest  Location
eslint    5.15.1  5.16.0  5.16.0

这里发生了什么事？这是由于某些错误软件包还是NPM本身的错误造成的？
作为临时解决方案，您可以安装最新的NPM：

npm i npm -g

npm i
然后
npm update
对我有效。
还遇到与报告相同的问题/错误尝试在本地安装npm，如果没有发现任何错误，尝试npm update，您应该在本地找到相关错误
