我在安装 angular 时遇到问题

Question

我在安装 angular 时遇到此错误。我想可能是 npm 路径的问题，但是如何解决呢。我做了 root 权限然后也得到了认证不受信任的错误。错误低于 -

我认为这是网络问题，如果您使用 Linux 那么；

sudo service network-manager restart

如果 windows 那么重启电脑应该可以解决这个问题。

也可能是 git 版本问题或节点版本问题，如果那是问题的话：

卸载 Git、Node.js、npm
安装Git
使用 npm
安装angular

或者简单地执行以下操作也可以解决问题：

npm uninstall -g angular-cli
npm cache clean
npm install -g rxjs
npm install -g @angular/cli
