我尝试使用角度 CLI github 页面上的说明在我的 Mac 上升级节点和角度 CLI，但升级不起作用。升级后说它安装了 Angular CLI v7.1.4，如果我执行“ng --version”，它仍然显示旧的 6.2.1 版本。有趣的是，看起来 npm install 正在将代码放入节点 10.10，这是节点的旧版本，而不是新版本 11.6。如何安装正确版本的 angular CLI？

The answer is that the n version manager for node was getting in the way of the angular CLI installation. I only had one version of node installed when I used n to list the versions avaiable, but it was doing installations into an old version of node. I uninstalled n because it was causing problems with multiple things on my machine and now the Angular CLI installs correctly.

sudo npm uninstall -g n

Then I installed the Angular CLI

npm install -g @angular/cli@latest

Now the angular CLI works fine.
