Vue.js 命令'；vue'；未找到Ubuntu 18.04

我已经在全球安装了nodejs

v10.19.0

我首先有npm（在我的项目分支和根上）：

valentin@valentin：~$npm i-g@vue/cli
npm警告弃用的内核-js@2.6.11：核心-js@I希望您已经检查了这些线程，@AmitP我已经检查了第一个线程，但是我还没有看到第二个线程。希望这能为我指明正确的方向。我以后会告诉你的。谢谢@AmitP更新我的路径命令确实有帮助。虽然我在这一次之前看到过这条线索，但我更加关注它（在这个问题上提出的解决方案太多了，所以我被许多其他来回的问题分散了注意力）。非常感谢。更新路径变量有帮助
