Question

我尝试使用angular CLI github页面上的说明对Mac上的node和angular CLI进行升级，但是升级无法正常进行。升级说它安装了Angular CLI v7.1.4之后，如果我执行“ ng --version”，它仍显示旧的6.2.1版本。有趣的是，看起来npm install将代码放入节点10.10中，该节点是该节点的旧版本，而不是新版本11.6。如何获得正确版本的angular CLI？

Answer 1

答案是节点的n版本管理器妨碍了角度CLI的安装。当我使用n列出可用的版本时，我仅安装了一个版本的节点，但是它正在安装到旧版本的节点中。我卸载了n，因为它导致我的计算机上发生多件事，现在Angular CLI已正确安装。

sudo npm卸载-g n

然后我安装了Angular CLI

npm install -g @ angular / cli @ latest

现在，角度CLI可以正常工作。

Angular CLI从6升级到7无法正常工作
