我在安装角度时遇到问题

Question

我在安装 angular 时遇到此错误。我认为可能是 npm 的路径问题，但如何解决。 我也获得了 root 权限，然后也得到了证书不受信任的错误。以下错误 -

    npm WARN uninstall not installed in /usr/local/lib/node_modules: "angular-cli"

如果你当时使用 Linux，我认为这是一个网络问题；

sudo service network-manager restart

如果是 windows，那么重启你的电脑应该可以解决这个问题。

如果这是问题，也可能是 git 版本问题或节点版本问题：

• 卸载 Git、Node.js、npm
• 安装 Git
• 通过 npm 安装 Node.js
• 安装角度

或者简单地以下也可以解决问题：

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