我怎样才能解决它？有什么问题吗？

我认为问题始于节点安装。 请使用检查节点版本

node -v
npm -v

节点必须是v8.5.0的最新版本，npm必须是5.4.1的最新版本

然后，请使用重新安装angular cli

npm install -g @angular/cli

然后检查版本

ng -v

版本将是1.4.1，如果一切正常，您可以创建项目为

ng new myNewProject

节点6.9.0或更高版本以及NPM 3或更高版本的Angular CLI要求。我当前的节点版本是v6.10.0。如何更新节点？使用nvm或从站点下载最新版本。我不知道您的操作系统，但网站上有一个安装指南。wellcome:Angular CLI对Node 6.9.0或更高版本以及NPM 3或更高版本的要求。我当前的Node版本是v6.10.0。如何更新Node？使用nvm或从网站下载最新版本。我不知道你的操作系统，但网站上有安装指南。你很好：
