我正在学习 npm 教程，我们正在学习的一个命令是 npm outdated -g 来检查是否有任何全局包已过期。
每当我运行该命令时，都会收到错误:
npm ERR! Cannot read property 'length' of undefined
npm ERR! A complete log of this run can be found in:
npm ERR! /Users/samlegros/.npm/_logs/2019-03-28T00_46_47_834Z-debug.log
我正在运行 npm 6.9.0 和 node 10.15.2。
这是与之相关的错误日志:

任何帮助将不胜感激。谢谢。
最佳答案
根据 github 上的 npm-cli，npm 存在过时的问题。它已于几周前修复，因此您可能必须等到 npm 的下一次更新发布才能发布修复程序。
关于node.js - 无法检查过时的全局 npm 包，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55388605/
